Backup encryption – double protection for your data
We all know how important it is to make a data backup. When something bad happens, you can restore it from backup. However, it is not enough to have a single backup. For example, you may worry someone may steal your backup and get the data on it.
Anyone can access to the image file, someone may modify or destroy it with intention. In order to protect your server from unauthorized access, you still need to set Windows Server backup encryption.
Encryption, by itself, can protect the confidentiality of data. Only the one who knows the password can access the image while others can not.
In short, you need to back up your files. You also need to encrypt the ones containing sensitive information. Backup and encryption offer you double protection for your data.
Set up Windows Server backup encryption on your server
There is a feature in Windows Server 2008/2012 named BitLocker Drive Encryption (can be also called BitLocker). It is a data protection feature that protects against data theft or exposure on data stored on fixed and removable data drives.
Let’s see how to set Windows Server 2008/2008 R2 backup encryption.
First, you should manually add this feature in the Server Manager.
1. Click Start, select Administrative Tools, and then click Server Manager.
2. In the Server Manager navigation pane, click Features, and then Add Features
3. Find out BitLocker Drive Encryption, and then click Next.
4. Click Install. When the wizard finishes, click Close, and then click Yes to restart the server if required.
Second, you should assign a drive letter to the backup hard disk drive
1. In the Server Manager navigation pane, click Storage, and then click Disk Management.
2. Right-click the backup drive, and then click Change Drive Letter and Path.
3. Click Add, choose a drive letter from the drop-down menu, and then click OK.
4. Click Yes, and then close Server Manager.
Third, to turn on BitLocker
1. Click Start, then Control Panel. Select System and Security, and then choose BitLocker Drive Encryption.
2. Click Turn on BitLocker for each of the drives that you want to protect, and then click Yes.
3. Choose the method that you want to use to unlock the drive after it is encrypted. If you choose to use a password, you can print it or save it in a file.
4. Click Start Encrypting. Depending on the size of the drive and the amount of data, it might take several hours to encrypt the drive.
5. When encryption is finished, unlock the backup drive using the BitLocker password that you created. Server backup, and file and folder restore should work as expected.
When drives, folders, and files are backed up by the server, an unencrypted version is saved to the server. During full system restore, this unencrypted version is copied to the computer. After a successful full system restore, you have to reactivate BitLocker on the server.
BitLocker Drive Encryption is only available in some editions of Windows 7/8/8.1/10, Windows Server 2008 and later.
Setting Windows Server 2012/2012 R2 backup encryption is quite similar to 2008 edition.
You cannot set encryption during backup with BitLocker Drive Encryption. There is another way which allows you to set encryption during backup.
