Verileri Korumak İçin Gerekli Temel Yapıtaşları Nelerdir?

WEBVTT 00:00:01.641 --> 00:00:04.801 Was sind die grundlegenden Bausteine, die zum Schutz von Daten erforderlich sind? 00:00:09.384 --> 00:00:13.766 Es gibt 5 Hauptkriterien, die wir im Zusammenhang mit Datensicherung im Auge behalten müssen. 00:00:13.906 --> 00:00:21.928 Durch diese Hauptkriterien haben wir die Möglichkeit, Maßnahmen zu ergreifen, um zu bestimmen, wie wir Backups erstellen und die Sicherheit auf welchem Niveau halten können. 00:00:21.969 --> 00:00:27.511 Erstens die Regelmäßigkeit des Backups, also das Backup-Intervall, der Zeitrahmen. 00:00:28.011 --> 00:00:29.612 Zweitens die Zeitplanung. 00:00:30.839 --> 00:00:31.900 Wie sollen wir sagen? 00:00:32.560 --> 00:00:37.064 Zum Beispiel einmal pro Woche im Juni. 00:00:37.244 --> 00:00:38.124 Wenn wir ein Beispiel geben. 00:00:39.284 --> 00:00:40.546 Speicherplatz. 00:00:41.287 --> 00:00:51.134 Ich möchte im Juni einmal pro Woche eine bestimmte Aufzeichnung auf einem externen USB-Laufwerk machen. 00:00:51.293 --> 00:00:52.395 Ich möchte ein Backup machen. 00:00:55.014 --> 00:00:56.394 Ich habe viele Fotos. 00:00:56.514 --> 00:01:03.076 Deshalb muss ich einige Daten komprimieren, damit mein externes USB-Laufwerk ausreicht. 00:01:03.477 --> 00:01:07.697 Denn ich werde bereits einmal pro Woche im Juni ein Backup machen. 00:01:07.958 --> 00:01:11.339 Deshalb werde ich ziemlich viel Platz benötigen. 00:01:12.279 --> 00:01:15.340 Priorisierung von Daten und Informationen nach Wichtigkeit, Qualität und Quantität. 00:01:15.440 --> 00:01:21.882 Was wir damit meinen, ist, dass diejenigen Daten, Dateien und Programme, die wichtiger sind, zuerst gesichert werden. 00:01:22.808 --> 00:01:28.351 Es ist sinnvoll, ein Backup zu haben, da der Wert hier wahrscheinlich größer sein wird. 00:01:28.531 --> 00:01:39.696 Zum Beispiel, wenn wir eine verschlüsselte Datei haben, in der wir unsere Bankpasswörter speichern, sollte das Sichern dieser Datei immer Priorität haben. 00:01:39.896 --> 00:01:43.538 Denn höchstwahrscheinlich ist es wichtiger als unser Familienurlaubsfoto. 00:01:50.069 --> 00:01:56.594 Es ist immer von Vorteil, die Maßnahmen zum Schutz unserer Daten zu ergreifen, bevor ein Notfall eintritt. 00:01:57.015 --> 00:02:01.899 Je früher wir handeln, desto höher ist die Chance, unsere Daten in hohem Maße wiederherzustellen. 00:02:02.739 --> 00:02:07.263 Es ist erforderlich, regelmäßig Backups zu erstellen und sie später in bestimmten Abständen zu überprüfen. 00:02:07.903 --> 00:02:12.367 Es ist sehr schwierig, genügend Zeit in unserem hektischen Leben für die Sicherung unserer Daten zu finden. 00:02:13.448 --> 00:02:19.413 Es ist eine kluge Entscheidung, Aktivitäten wie Datensicherungsmaßnahmen in einen Zeitplan zu integrieren. 00:02:21.226 --> 00:02:23.468 Welche Art von Daten und Informationen sollten gesichert werden? 00:02:27.953 --> 00:02:28.913 Was haben wir gerade gesagt? 00:02:28.994 --> 00:02:34.899 Zum Beispiel, wenn es rechtliche oder finanzielle Daten gibt, müssen wir sie 7 Jahre lang aufbewahren. 00:02:35.180 --> 00:02:39.083 Deshalb müssen diese Daten während dieser 7 Jahre kontinuierlich gesichert werden. 00:02:39.844 --> 00:02:43.648 Dies erfordert ernsthaft Platz. 00:02:45.252 --> 00:02:47.534 Wie können wir also diesen Platz schaffen? 00:02:47.734 --> 00:02:52.677 Auch wenn wir keinen Speicherplatz erstellen können, können wir den vorhandenen Speicherplatz effizient nutzen, indem wir einige Maßnahmen ergreifen. 00:02:52.757 --> 00:02:57.719 Zum Beispiel ist es möglich, auf die meisten von uns verwendeten Anwendungen und Programme über das Internet zuzugreifen. 00:02:57.839 --> 00:03:00.641 Deshalb ist es nicht notwendig, Anwendungen und Programme zu sichern. 00:03:01.501 --> 00:03:06.083 Anwendungen nehmen nicht nur Speicherplatz ein, sondern stellen auch eine zusätzliche Belastung und Kosten für Virenscans dar. 00:03:06.264 --> 00:03:10.946 Es ist die richtige Entscheidung, Online-Anwendungen zu nutzen. 00:03:12.950 --> 00:03:18.675 Wenn wir Online-Anwendungen verwenden, ist es wahrscheinlicher, dass wir vor Viren und schädlicher Malware geschützt sind. 00:03:19.416 --> 00:03:28.725 Auf diese Weise können wir mögliche Übertragungen von Viren oder schädlicher Malware in unsere Datensicherung verhindern. 00:03:29.642 --> 00:03:34.205 Deshalb reicht es für uns hauptsächlich aus, nur Dateien und Ordner zu sichern. 00:03:34.725 --> 00:03:44.290 Wir können uns fragen, ob wir dieses Programm oder diese Anwendung wirklich benötigen, um zu entscheiden, ob Programme und Anwendungen gesichert werden müssen. 00:03:46.952 --> 00:03:49.513 Welche Tools können wir also für die Sicherung verwenden? 00:03:51.894 --> 00:03:56.617 Spezielle Backup-Software erleichtert die Sicherung erheblich. 00:03:57.341 --> 00:04:03.108 Mit automatischen Befehlen besteht die Möglichkeit, dass unsere Dateien in Bluetooth-Netzwerken automatisch hochgeladen werden. 00:04:03.769 --> 00:04:08.054 Deshalb wird es für uns in der Regel ausreichen, hauptsächlich nur Dateien und Ordner zu sichern. 00:04:08.435 --> 00:04:14.529 Dafür wird in der Regel ein Verknüpfungsordner auf dem Desktop vorhanden sein. 00:04:15.110 --> 00:04:20.851 Wir dürfen nicht vergessen, dass unsere in die Cloud übertragenen Daten nicht mehr nur unter unserer Aufsicht stehen. 00:04:21.311 --> 00:04:23.071 Was meinen wir damit? 00:04:23.211 --> 00:04:27.932 Wir werden später etwas ausführlicher auf dieses Thema eingehen. 00:04:28.572 --> 00:04:34.873 Aber auch wenn die Daten in die Cloud übertragen werden, bedeutet dies nicht, dass sie einfach verschwinden. 00:04:34.973 --> 00:04:41.014 Diese Daten werden physisch an einem anderen Ort auf der Welt gespeichert und aufbewahrt. 00:04:42.335 --> 00:04:42.895 Was bedeutet das? 00:04:43.575 --> 00:04:52.197 Die Personen in dem Unternehmen, das diesen Service zur Speicherung dieser Daten an einem anderen Ort auf der Welt anbietet, können auf diese Daten zugreifen. 00:04:53.357 --> 00:05:00.339 Auf der anderen Seite könnten gelöschte Daten, da sie von ihnen gesichert wurden, möglicherweise nicht vollständig gelöscht werden, auch wenn wir sie nicht sehen. 00:05:00.519 --> 00:05:12.959 Deshalb, obwohl unser Leben durch die Cloud-Computing-Technologie erleichtert wird und Daten manchmal automatisch mit automatischen Befehlen gesichert werden, sollten wir nicht vergessen, 00:05:13.119 --> 00:05:16.821 dass die in die Cloud übertragenen Daten auch unter die Aufsicht anderer geraten können. 00:05:20.122 --> 00:05:22.022 Wo werden die gesicherten Dateien gespeichert? 00:05:22.222 --> 00:05:25.483 Wie können wir Speicherplatz in dem Bereich, in dem die Daten gespeichert sind, sparen? 00:05:28.803 --> 00:05:32.505 Das Backup-Medium muss groß genug sein, um alle Daten zu speichern. 00:05:33.446 --> 00:05:38.988 Die gesicherten Dateien werden entweder auf einem USB-Stick oder in einer Cloud-Computing-Umgebung gespeichert und aufbewahrt. 00:05:39.844 --> 00:05:47.626 Manchmal reicht möglicherweise nur ein USB-Stick oder eine externe Festplatte aus, entgegen unserer Annahmen. 00:05:48.126 --> 00:05:57.008 Aber wir dürfen nicht vergessen, dass die physischen USB-Sticks oder externe Festplatten, die wir verwenden, uns später Kosten verursachen werden. 00:05:57.068 --> 00:05:58.428 Was wir damit meinen, ist folgendes. 00:05:58.609 --> 00:06:04.430 Angenommen, der Speicherplatz der Festplatte unseres Computers beträgt 1 TB. 00:06:06.380 --> 00:06:08.861 Wir haben diesen 1 TB vollständig belegt. 00:06:09.722 --> 00:06:15.504 Und sagen wir, wir möchten jedes Mal die Hälfte davon, also 500 GB, sichern. 00:06:16.445 --> 00:06:25.269 Wenn wir zweimal ein Backup machen, besteht eine hohe Wahrscheinlichkeit, dass wir einen USB-Stick mit der gleichen Kapazität von 1 TB benötigen, um diesen zu füllen. 00:06:25.389 --> 00:06:28.410 Was passiert, wenn wir ein drittes oder viertes Backup machen? 00:06:28.450 --> 00:06:30.711 Kaufen wir einen neuen USB-Stick? 00:06:30.772 --> 00:06:32.812 Oder eine externe Festplatte? 00:06:33.273 --> 00:06:34.962 Das ist sehr kostspielig. 00:06:35.142 --> 00:06:42.126 Deshalb ist es ratsam, zu lernen, wie man Daten komprimiert, um Speicherplatz freizugeben. 00:06:42.306 --> 00:06:49.249 Zwei, wir müssen uns darauf konzentrieren, wie wir Cloud-Computing sicher nutzen können, und dazu detaillierte Recherchen durchführen, 00:06:49.309 --> 00:06:51.089 um unser Wissen zu erweitern. 00:06:53.931 --> 00:06:55.551 Wann sollten wir ein Backup machen? 00:06:57.572 --> 00:07:03.415 Wenn wir ein automatisches Backup-System haben, sollte täglich ein Backup durchgeführt werden. 00:07:04.605 --> 00:07:13.147 Was wir damit meinen ist, wenn wir Cloud-Computing haben, sollte der Computer im Hintergrund Backup-Prozesse im Computer selbst 00:07:13.187 --> 00:07:13.607 durchführen. 00:07:14.667 --> 00:07:20.888 Wenn im Datenspeicher nur geringfügige Änderungen vorgenommen wurden und der manuelle Aufwand groß ist, kann auch eine wöchentliche Sicherung ausreichen. 00:07:26.529 --> 00:07:29.430 Wie können wir sicherstellen, dass die Daten wiederhergestellt werden können? 00:07:32.199 --> 00:07:38.342 Wenn unser Mobilgerät oder Computer beschädigt ist, können wir die verlorenen Daten aus dem Backup-System wiederherstellen. 00:07:38.822 --> 00:07:41.444 Dieser Vorgang erfordert bestimmte Infrastrukturanforderungen. 00:07:42.164 --> 00:07:49.808 Zum Beispiel, wenn bei einer Naturkatastrophe das Internet beschädigt wird oder die mit dem Internet verbundenen Systeme beschädigt werden, können wir die Daten möglicherweise nicht auf die neuen Computer übertragen, 00:07:49.848 --> 00:07:52.649 die die beschädigten Computer ersetzen. 00:07:53.790 --> 00:08:00.553 Besonders in Unternehmen und offiziellen Organisationen ist es äußerst wichtig, sicherzustellen, dass die erforderliche Infrastruktur sicher funktioniert. 00:08:01.718 --> 00:08:07.683 Deshalb ist es manchmal sinnvoll, sowohl physische als auch Online-Backup-Methoden gleichzeitig zu verwenden. 00:08:10.525 --> 00:08:14.468 Was sind also die zusätzlichen Informationen, die wir zu diesem Thema wissen müssen? 00:08:17.947 --> 00:08:21.972 Das vollständige Wiederherstellen von Unternehmensdaten ist ein kostspieliger Vorgang. 00:08:22.092 --> 00:08:24.535 Nicht nur kostspielig, sondern sehr kostspielig. 00:08:24.655 --> 00:08:32.886 Je nach Komplexität des Computers oder Systems ist es ratsam, für einen Wiederherstellungsvorgang eine Zeit von 5-10 Stunden einzuplanen, 00:08:32.986 --> 00:08:35.089 was im besten Fall ist. 00:08:36.539 --> 00:08:37.219 auffällig ist. 00:08:37.820 --> 00:08:42.160 Es kann nützlich sein, ein Abbild aller Festplatten zu erstellen. 00:08:42.501 --> 00:08:47.482 Auf diese Weise können wir den Computer auch nach einem Festplattenausfall wie beim Backup wiederherstellen. 00:08:47.763 --> 00:08:49.124 Was wir damit meinen, ist folgendes. 00:08:49.604 --> 00:08:52.865 Stellen Sie sich vor, wir machen ein Foto von allem, was auf unserer Festplatte lesbar ist. 00:08:53.225 --> 00:09:01.929 Das bedeutet, dass alles, was auf unserer Festplatte lesbar ist, fotografiert und auf andere Weise übertragen wird, also geklont wird. 00:09:02.469 --> 00:09:02.970 Was machen wir? 00:09:03.010 --> 00:09:06.556 Wir erstellen sozusagen ein Zwilling unserer Festplatte. 00:09:07.117 --> 00:09:12.206 Auf diese Weise können wir jedes Gerät weiterhin wie unseren eigenen Computer verwenden.

WEBVTT 00:00:01.641 --> 00:00:04.801 What are the essential building blocks to protect data? 00:00:09.384 --> 00:00:13.766 There are 5 main criteria to keep in mind regarding data backup. 00:00:13.906 --> 00:00:21.928 Thanks to these main criteria, we have the chance to take some measures on how to perform data backup and maintain security at what level. 00:00:21.969 --> 00:00:27.511 The first one is the regularity of backups, the backup interval, time interval. 00:00:28.011 --> 00:00:29.612 The second is time planning. 00:00:30.839 --> 00:00:31.900 How should we say? 00:00:32.560 --> 00:00:37.064 For example, let's say once a week in June. 00:00:37.244 --> 00:00:38.124 For example. 00:00:39.284 --> 00:00:40.546 Data storage area. 00:00:41.287 --> 00:00:51.134 I want to make a specific recording on an external USB once a week in June. 00:00:51.293 --> 00:00:52.395 I want to back up. 00:00:55.014 --> 00:00:56.394 I have a lot of photos. 00:00:56.514 --> 00:01:03.076 Therefore, I should compress some data to store it so that my external USB can be enough for me. 00:01:03.477 --> 00:01:07.697 Because I will already back up once a week throughout June. 00:01:07.958 --> 00:01:11.339 That's why I will need quite a lot of space. 00:01:12.279 --> 00:01:15.340 Selection of data and information, priority, quality, and quantity. 00:01:15.440 --> 00:01:21.882 What we mean is to prioritize the data, files, and programs that are more important first. 00:01:22.808 --> 00:01:28.351 It is beneficial to back up because most likely the value will be greater here. 00:01:28.531 --> 00:01:39.696 For example, if we have an encrypted file where we store our banking passwords, backing up this file should always be a priority. 00:01:39.896 --> 00:01:43.538 Because most likely it will be more important than our family vacation photos. 00:01:50.069 --> 00:01:56.594 It is always advantageous to implement the measures we need to take to protect our data before an emergency occurs. 00:01:57.015 --> 00:02:01.899 The earlier we act, the higher the chance we have of recovering our data to a significant degree. 00:02:02.739 --> 00:02:07.263 We need to repeat backups and check them at specific intervals later on. 00:02:07.903 --> 00:02:12.367 It is quite difficult to create enough time in our busy lives to ensure data security. 00:02:13.448 --> 00:02:19.413 Scheduling activities like data backup for data security will be a wise decision. 00:02:21.226 --> 00:02:23.468 What types of data and information should be backed up? 00:02:27.953 --> 00:02:28.913 What did we just say? 00:02:28.994 --> 00:02:34.899 For instance, if there is legal or financial data, we need to keep it for 7 years. 00:02:35.180 --> 00:02:39.083 Therefore, this data needs to be backed up continuously for these 7 years. 00:02:39.844 --> 00:02:43.648 This will require a significant amount of space. 00:02:45.252 --> 00:02:47.534 So, how can we create this space? 00:02:47.734 --> 00:02:52.677 Even if we cannot create space, we can take some measures to use the space properly and efficiently. 00:02:52.757 --> 00:02:57.719 For example, it is possible to access most of the applications and programs we use via the internet. 00:02:57.839 --> 00:03:00.641 Therefore, there is no need for us to back up applications and programs. 00:03:01.501 --> 00:03:06.083 Applications both take up space and create an additional burden and cost for virus scanning. 00:03:06.264 --> 00:03:10.946 Using applications online will be the most correct decision. 00:03:12.950 --> 00:03:18.675 When we use online applications, it becomes more possible for us to stay away from viruses and harmful malware. 00:03:19.416 --> 00:03:28.725 In this way, it will be possible for us to prevent a possible transfer of virus or malicious software within our data backup. 00:03:29.642 --> 00:03:34.205 Therefore, mainly backing up only files and folders is sufficient for us. 00:03:34.725 --> 00:03:44.290 We can search for an answer by asking ourselves how much we need this program or this application in terms of whether programs and applications need to be backed up. 00:03:46.952 --> 00:03:49.513 So, what tools can we use for backup? 00:03:51.894 --> 00:03:56.617 Special backup software allows us to easily fulfill the purpose of backup. 00:03:57.341 --> 00:04:03.108 With its automatic commands, there is a chance for our files to be uploaded to Bluetooth networks, that is, Bluetooth exchange networks. 00:04:03.769 --> 00:04:08.054 Therefore, it will be sufficient for us to mainly back up only files and folders. 00:04:08.435 --> 00:04:14.529 For this, there will generally be a connected folder on the desktop. 00:04:15.110 --> 00:04:20.851 We must not forget that with cloud computing, our transferred data is no longer solely under our supervision. 00:04:21.311 --> 00:04:23.071 What do we mean by this? 00:04:23.211 --> 00:04:27.932 We will delve into this topic in more detail at a later time. 00:04:28.572 --> 00:04:34.873 But even though the data goes to the cloud, it doesn't mean it disappears into thin air. 00:04:34.973 --> 00:04:41.014 These data are physically stored and kept in a different location in the world in a certain way. 00:04:42.335 --> 00:04:42.895 What does this mean? 00:04:43.575 --> 00:04:52.197 It means that the individuals at the company providing services related to storing these data in a different part of the world can access this data. 00:04:53.357 --> 00:05:00.339 On the other hand, since they back up the data we delete, even if we don't see it, it may not be completely erased. 00:05:00.519 --> 00:05:12.959 Therefore, although our lives may be facilitated by cloud computing and data is sometimes and generally backed up automatically with automatic commands, let's not forget 00:05:13.119 --> 00:05:16.821 that the data we transfer with cloud computing also falls under the supervision of others. 00:05:20.122 --> 00:05:22.022 Where are the backed-up files stored? 00:05:22.222 --> 00:05:25.483 How can we save space in the storage area? 00:05:28.803 --> 00:05:32.505 The backup media should be large enough to store all the data within it. 00:05:33.446 --> 00:05:38.988 The backed-up files will either be stored on a USB flash drive or in a cloud computing environment. 00:05:39.844 --> 00:05:47.626 Sometimes, contrary to what we might think, maybe just a USB flash drive or an external hard drive will suffice for the task. 00:05:48.126 --> 00:05:57.008 But we must not forget that the physical USB flash drives or an external hard drive we use will incur costs in the future. 00:05:57.068 --> 00:05:58.428 What we mean by this is as follows. 00:05:58.609 --> 00:06:04.430 For example, let's say the memory of our computer's hard drive is 1 TB. 00:06:06.380 --> 00:06:08.861 Let's say we have completely filled this 1 TB. 00:06:09.722 --> 00:06:15.504 And let's say we want to back up half of it, which is 500 GB, each time. 00:06:16.445 --> 00:06:25.269 When we back up twice, we most likely have the possibility of filling a USB flash drive with the same capacity as this 1 TB. 00:06:25.389 --> 00:06:28.410 So what will happen when we do the third, fourth backup? 00:06:28.450 --> 00:06:30.711 Will we buy a new USB flash drive? 00:06:30.772 --> 00:06:32.812 Or will we buy an external hard drive? 00:06:33.273 --> 00:06:34.962 This is very costly. 00:06:35.142 --> 00:06:42.126 Therefore, it is beneficial for us to learn how to compress the data in order to allocate storage space. 00:06:42.306 --> 00:06:49.249 Two, we need to focus on how to use cloud computing securely and conduct detailed research on this topic to increase our knowledge. 00:06:49.309 --> 00:06:51.089 When should we back up? 00:06:53.931 --> 00:06:55.551 If we have an automatic backup system, a backup operation should be run daily. 00:06:57.572 --> 00:07:03.415 What we mean by this is if we have cloud computing, the computer in the cloud computing should perform the backup operation on its own in the background processes. 00:07:04.605 --> 00:07:13.147 If there are only small changes in the data stock, and manual effort is significant, weekly backup may be sufficient. 00:07:26.529 --> 00:07:29.430 How can we ensure that the data can be restored? 00:07:32.199 --> 00:07:38.342 When our mobile device or computer is damaged, we can recover the lost data by copying it back from the backup system. 00:07:38.822 --> 00:07:41.444 This process requires certain infrastructure requirements. 00:07:42.164 --> 00:07:49.808 For example, in the event of a natural disaster, if the internet is damaged or systems related to the internet are damaged, we may not be able to restore the data to the new computers that will replace the damaged computers. 00:07:53.790 --> 00:08:00.553 Especially in corporate and official organizations, it is extremely important to ensure that the adequate infrastructure operates securely. 00:08:01.718 --> 00:08:07.683 Therefore, sometimes it is beneficial to use both physical and online backup methods simultaneously. 00:08:10.525 --> 00:08:14.468 So, what are the additional information we need to learn about the subject? 00:08:17.947 --> 00:08:21.972 Completely reloading corporate data is a costly process. 00:08:22.092 --> 00:08:24.535 Not only costly, but a very costly process. 00:08:24.655 --> 00:08:32.886 Depending on how complex the computer or systems are set up, it is advisable to allocate a time frame of 5-10 hours for a restoration process, 00:08:32.986 --> 00:08:35.089 which is the best-case scenario. 00:08:36.539 --> 00:08:37.219 stands out. 00:08:37.820 --> 00:08:42.160 Backing up an image of the entire disk drive can be useful. 00:08:42.501 --> 00:08:47.482 This way, we can restore the computer just like during the backup process even after a disk failure. 00:08:47.763 --> 00:08:49.124 What we mean by this is as follows. 00:08:49.604 --> 00:08:52.865 Let's imagine that we took a photo of everything readable on our hard drive. 00:08:53.225 --> 00:09:01.929 This is like taking a photo of everything that can be read on our hard drive and transferring it in another way, like cloning it. 00:09:02.469 --> 00:09:02.970 What are we doing? 00:09:03.010 --> 00:09:06.556 We are creating a kind of twin of our hard drive. 00:09:07.117 --> 00:09:12.206 This way, it is possible to continue using any device as if we are using our own computer.

WEBVTT 00:00:01.641 --> 00:00:04.801 Verileri korumak için gerekli temel yapı taşları nelerdir? 00:00:09.384 --> 00:00:13.766 Veri yedekleme ile ilgili aklımıza tutmamız gereken 5 tane ana kriter var. 00:00:13.906 --> 00:00:21.928 Bu ana kriter sayesinde bizim veri yedeklemeyi nasıl yapabileceğimiz ve güvenliği nasıl seviyede tutabileceğimize dair bazı önlemler alma şansımız bulunur. 00:00:21.969 --> 00:00:27.511 Bunlardan birincisi yedeklemenin düzenliliği yani yedekleme aralığı, zaman aralığı. 00:00:28.011 --> 00:00:29.612 İkincisi zaman planlaması. 00:00:30.839 --> 00:00:31.900 Yani nasıl diyelim? 00:00:32.560 --> 00:00:37.064 Haziran ayında haftada bir gün mesela diyelim. 00:00:37.244 --> 00:00:38.124 Örnek verirsek. 00:00:39.284 --> 00:00:40.546 Veri depolama alanı. 00:00:41.287 --> 00:00:51.134 Ben haziran haftada bir, bir harici USB belli kayıt yapmak istiyorum. 00:00:51.293 --> 00:00:52.395 Yedekleme yapmak istiyorum. 00:00:55.014 --> 00:00:56.394 Çok fazla fotoğrafım var. 00:00:56.514 --> 00:01:03.076 Bu yüzden bazı verileri sıkıştırarak saklamalıyım ki benim harici USB beldeyim bana yetebilsin. 00:01:03.477 --> 00:01:07.697 Çünkü zaten haftada bir yedekleme yapacağım Haziran ayı boyunca. 00:01:07.958 --> 00:01:11.339 Bu sebeple oldukça fazla yere ihtiyacım olacak. 00:01:12.279 --> 00:01:15.340 Veri ve bilgi seçimi öncelik, nitelik ve nicelik. 00:01:15.440 --> 00:01:21.882 Bundan kastettiğimiz şey hangi veriler ve dosyalar ve programlar daha önemli ise onları ilk olarak. 00:01:22.808 --> 00:01:28.351 Yedeklememizde fayda var çünkü büyük ihtimalle daha büyük değer burada olacaktır. 00:01:28.531 --> 00:01:39.696 Örneğin bankacılık şifrelerimizi sakladığımız eğer bir şifrelenmiş dosyamız varsa bu dosyayı yedeklememiz her zaman öncelikle olmalıdır. 00:01:39.896 --> 00:01:43.538 Çünkü büyük ihtimalle aile tatili fotoğrafımızdan daha önemli olacaktır. 00:01:50.069 --> 00:01:56.594 Verilerimizi korumak için almamız gereken önlemleri acil bir durum gerçekleşmeden devreye sokmamızda her zaman fayda var. 00:01:57.015 --> 00:02:01.899 Ne kadar erken davranırsak o kadar yüksek derecede verimizi kurtarma şansına sahip oluruz. 00:02:02.739 --> 00:02:07.263 Yedeklemeleri tekrarlamamız ve daha sonra belirli aralıklarla kontrol etmemiz gerekmektedir. 00:02:07.903 --> 00:02:12.367 Gün delik hayatımızda veri güvenliğimizi sağlamak için yeterince zaman yaratmak oldukça zordur. 00:02:13.448 --> 00:02:19.413 Veri güvenliğine dair yedekleme gibi aktiviteleri, etkinlikleri bir zaman planına oturtmamız yerinde bir karar olacaktır. 00:02:21.226 --> 00:02:23.468 Hangi tür veri ve bilgiler yedeklenmelidir? 00:02:27.953 --> 00:02:28.913 Az önce ne demiştik? 00:02:28.994 --> 00:02:34.899 Mesela hukuksal veya mali bir veri varsa bunu 7 yıl boyunca tutmamız gerekiyor. 00:02:35.180 --> 00:02:39.083 Bu yüzden bu 7 yıl boyunca verinin sürekli yedeklenmesi lazım. 00:02:39.844 --> 00:02:43.648 Bu da ciddi anlamda bir alan gerektirecektir. 00:02:45.252 --> 00:02:47.534 Peki bu alanı nasıl oluşturabiliriz? 00:02:47.734 --> 00:02:52.677 Alanı oluşturamasak bile alanı düzgün ve verimli kullanmak için bazı önlemler alabiliriz. 00:02:52.757 --> 00:02:57.719 Mesela kullandığımız uygulama ve programların çoğuna internet yoluyla erişmemiz mümkün. 00:02:57.839 --> 00:03:00.641 O yüzden uygulama ve programları yedeklememize gerek yok. 00:03:01.501 --> 00:03:06.083 Uygulamalar hem yer tutar hem de virüs taraması için bize ek bir külfet ve maliyet oluştururlar. 00:03:06.264 --> 00:03:10.946 Çevrim için uygulamaları kullanmak en doğru karar olacaktır. 00:03:12.950 --> 00:03:18.675 Çevrim içi uygulamaları kullandığımız zaman virüsler ve zararlı kötücül yazılımlardan uzak kalmamız daha mümkün olur. 00:03:19.416 --> 00:03:28.725 Bu şekilde de bizim veri yedeklememiz içerisinde olası bir virüs veya kötücül yazılım transferini engellememiz mümkün olacaktır. 00:03:29.642 --> 00:03:34.205 Bu nedenle ağırlıklı olarak sadece dosya ve klasörleri yedeklemek bizim için yeterlidir. 00:03:34.725 --> 00:03:44.290 Program ve uygulamaların yedeklenip yedeklenmemesi gerekne dair kendimize bu programa veya bu uygulamaya ne kadar ihtiyacımız var diye sorarak bir yanıt arayabiliriz. 00:03:46.952 --> 00:03:49.513 Peki yedekleme için hangi araçları kullanabiliriz? 00:03:51.894 --> 00:03:56.617 Özel yedekleme yazılımları yedekleme amacını oldukça kolay yerine getirebilmemizi sağlar. 00:03:57.341 --> 00:04:03.108 otomatik komutlarıyla blut ağlara yani blut değişimi ağlarına dosyalarımızın kendinden yüklenme şansı vardır. 00:04:03.769 --> 00:04:08.054 Bu nedenle ağırlıklı olarak sadece dosya ve klasörleri yedeklemek bizim için yeterli olacak. 00:04:08.435 --> 00:04:14.529 Bunun için de genellikle masa üstünde bir bağlantı klasörü bulunacaktır. 00:04:15.110 --> 00:04:20.851 Unutmamalıyız ki bulut bilişimi aktardığımız verilerimiz artık sadece bizim gözetimimiz altında değildir. 00:04:21.311 --> 00:04:23.071 Bundan kastettiğimiz şey nedir? 00:04:23.211 --> 00:04:27.932 Bu konuya ilerleyen vakitte biraz daha detaylı bir şekilde değineceğiz. 00:04:28.572 --> 00:04:34.873 Ama veri her ne kadar buluta gitse de buluta gitmesi havaya uçtuğu anlamına gelmiyor. 00:04:34.973 --> 00:04:41.014 Bu veriler belirli bir şekilde fiziksel olarak dünyanın farklı bir yerinde depolanıyor ve saklanıyor. 00:04:42.335 --> 00:04:42.895 Bu ne demek? 00:04:43.575 --> 00:04:52.197 Dünyanın farklı yerinde bu verilerin bu şekilde saklanmasıyla ilgili hizmet veren firmadaki kişiler bu verilere erişebilir demek. 00:04:53.357 --> 00:05:00.339 Diğer bir yandan sildiğimiz veriler onlar verileri yedeklediği için biz görmesek bile tamamen silinmeyebilir. 00:05:00.519 --> 00:05:12.959 Bu sebeple bulut bilişimle ilgili her ne kadar hayatımız kolaylaşsa da otomatik komutlarla otomatik olarak bazen ve genellikle veriler yedeklense de Unutmayalım 00:05:13.119 --> 00:05:16.821 ki bulut bilişimi aktardığımız veriler başkalarının gözetiminin altına da girer. 00:05:20.122 --> 00:05:22.022 Yedeklenmiş dosyalar nerede saklanır? 00:05:22.222 --> 00:05:25.483 Veri saklanan alandan nasıl tasarruf edebiliriz? 00:05:28.803 --> 00:05:32.505 Yedekleme ortamı içindeki tüm verileri depolayacak kadar büyük olmalıdır. 00:05:33.446 --> 00:05:38.988 Yedeklenen dosyalar ya bir USB bellekte ya da bulut bilişimi ortamında depolanacak ve saklanacaktır. 00:05:39.844 --> 00:05:47.626 Bazen düşündüğümüzün aksine belki sadece bir USB bellek veya harici bir sabit sürücü yeterli olarak görevi yerine getirecektir. 00:05:48.126 --> 00:05:57.008 Fakat unutmamalıyız ki kullandığımız fiziksel USB harici bellekler veya bir sabit sürücü bize ilerleyen zamanlarda maliyet getirecektir. 00:05:57.068 --> 00:05:58.428 Bundan kastettiğimiz şey şu. 00:05:58.609 --> 00:06:04.430 Mesela diyelim ki bilgisayarımızın sabit sürücüsünün hafızası 1 TB olsun. 00:06:06.380 --> 00:06:08.861 Biz bu 1 TB'ı tamamen doldurmuş olalım. 00:06:09.722 --> 00:06:15.504 Bunun içerisinde de diyelim her seferinde yarısı yani 500 GB'ı biz yedeklemek istiyoruz. 00:06:16.445 --> 00:06:25.269 İki kere yedekleme yaptığımızda büyük ihtimalle bizim bu 1 TB'a denk gelecek aynı kapasitedeki bir USB bellek doldurma ihtimalimiz var. 00:06:25.389 --> 00:06:28.410 Peki biz üçüncü, dördüncü yedekleme yaptığımızda ne olacak? 00:06:28.450 --> 00:06:30.711 Yeni bir USB bellek mi alacağız? 00:06:30.772 --> 00:06:32.812 Veya harici sabit sürücü alacağız? 00:06:33.273 --> 00:06:34.962 Bu Çok maliyetlidir. 00:06:35.142 --> 00:06:42.126 Bu sebeple depolama alanından tahsaf etmek için bir, verileri nasıl sıkıştıracağımızı öğrenmemizde fayda vardır. 00:06:42.306 --> 00:06:49.249 İki, bulut bilişimi güvenlikli olarak nasıl kullanabileceğimize odaklanmamızda ve bu konuyla ilgili detaylı araştırma yapmamıza, 00:06:49.309 --> 00:06:51.089 bilgimizi artırmamıza gerek vardır. 00:06:53.931 --> 00:06:55.551 Ne zaman yedekleme yapmalıyız? 00:06:57.572 --> 00:07:03.415 Otomatik bir yedekleme sistemine sahipsek günlük olarak bir yedekleme çalıştırması gerçekleştirilmelidir. 00:07:04.605 --> 00:07:13.147 Bunun alkası ettiğimiz şey eğer bulut bilişim varsa bulut bilişimde bilgisayar, arka plan işlemleri içerisinde yedekleme işlemini bilgisayarın kendi kendine 00:07:13.187 --> 00:07:13.607 gerçekleştirmesi gerekir. 00:07:14.667 --> 00:07:20.888 Veri stokunda yalnızca küçük değişiklikler varsa, manuel çaba çok büyükse haftalık yedekleme de yeterli olabilir. 00:07:26.529 --> 00:07:29.430 Verilerin geri yüklenebileceğinden nasıl emin olabiliriz? 00:07:32.199 --> 00:07:38.342 Mobil cihazımız ya da bilgisayarımız hasar gördüğünde kayıp verileri yedekleme sisteminden geri kopyalayarak kurtarabiliriz. 00:07:38.822 --> 00:07:41.444 Bu işlem belirli altyapı gereksinlerini doğurmaktadır. 00:07:42.164 --> 00:07:49.808 Örneğin bir doğal afet anında eğer internet hasar görürse veya internetle ilgili sistemler hasar görürse, hasar gören bilgisayarlarının yerine gelecek 00:07:49.848 --> 00:07:52.649 yeni bilgisayarlara verileri geri yükleyemeyebiliriz. 00:07:53.790 --> 00:08:00.553 Özellikle kurumsal ve resmi kuruluşlarda yeterli altyapının güvenli bir şekilde işleyeceğinden emin olmamız son derece önemlidir. 00:08:01.718 --> 00:08:07.683 Dolayısıyla bazen hem fiziksel hem de çevrim içi yedekleme yöntemlerini aynı anda kullanmakta fayda vardır. 00:08:10.525 --> 00:08:14.468 Peki konuyla ilgili öğrenmemiz gereken ek bilgilenmelerdir. 00:08:17.947 --> 00:08:21.972 Kurumsal verilerin tamamen yeniden yüklenmesi maliyetli bir işlemdir. 00:08:22.092 --> 00:08:24.535 Sadece maliyetli değil, çok maliyetli bir işlemdir. 00:08:24.655 --> 00:08:32.886 Bilgisayarın ya da sistemlerin ne kadar karmaşık kurulduğuna bağlı olarak bir geri yükleme işlemi için 5-10 saat arası bir süre hesaplarınızda fayda vardır 00:08:32.986 --> 00:08:35.089 ki bu iyi ihtimal olarak. 00:08:36.539 --> 00:08:37.219 göze çarpar. 00:08:37.820 --> 00:08:42.160 Sabit disklerin yani bütün diskin bir görüntüsünü yedeklemek faydalı olabilir. 00:08:42.501 --> 00:08:47.482 Bu şekilde bilgisayarı bir sabit disk arzasından sonra bile yedekleme sırasında olduğu gibi geri yükleyebiliriz. 00:08:47.763 --> 00:08:49.124 Bundan kastettiğimiz şey şu. 00:08:49.604 --> 00:08:52.865 Gördüğümüz şey neyse bunun fotoğrafını çektiğimizi düşünelim. 00:08:53.225 --> 00:09:01.929 Bu da bizim sabit sürücümüz içerisinde okunabilen ne kadar şey varsa bunun fotoğrafının çekilip başka bir şekilde aktarıldığını yani klonlandığını düşünelim. 00:09:02.469 --> 00:09:02.970 Ne yapıyoruz? 00:09:03.010 --> 00:09:06.556 Biz sabit sürücümüzün bir nevi ikizini yaratmış oluyoruz. 00:09:07.117 --> 00:09:12.206 Bu şekilde herhangi bir cihazı kendi bilgisayarımızı kullanıyormuş gibi kullanmaya devam etmemiz mümkün.
