Encrypted volumes may get corrupt just like regular volumes. Therefore, it is always a good idea to have a backup.
There are two types of backups:
- Encrypted Backup
Sector-level backup that is performed when the volume is dismouned. - Unencrypted Backup
File-level backup that is performed if the encrypted volume is mounted.
Some backup programs report that they cannot backup 'bcldr.bin' file that is the file with encryption key and it is locked by BCVE. You should configure the backup program to skip this file.
Note: The volume that hosts the OS is only dismounted when your PC is powered off. Hence, to create a backup of the system volume in encrypted state you will need to use backup software that supports creating backups from a bootable USB. One example is Acronis True Image.
