backup & bitlocker

Thread solved

Hello. My task is to make a backup copy of the system, in case it crashes. So that in the future it would be possible to recover if some program or driver fails (or a virus).
But the task is complicated by the fact that my disks are encrypted with a bitlocker. Do I need to suspend bitlocker protection before creating a backup or is it not required?
Will I be able to restore the system with the help of such a copy? In what condition will the disks be after recovery? With bitlocker turned on, or will I have to reconfigure it?

thank

Max, welcome to these public User Forums.

If you have ATI 2020 installed in Windows, then it can create a backup of your disk drive from that application while the drive is unlocked for Bitlocker.  The backup will be of the unlocked drive with no encryption, so you would need to either store it on an unlocked Bitlocker drive or else use the password encryption option for the backup (in the Advanced Options).

For recovery, if you have a backup as above, then it would recover the unlocked drive and you would then need to enable Bitlocker again.

ATI cannot backup encrypted drives unless they have been unlocked first, and the ATI rescue media does not have support for Bitlocker unless this is added by the user.

The MVP Custom PE Builder tool can create WinPE rescue media and inject BitLocker support to it during the build process.  You would still need to unlock the encrypted drive from the WinPE standalone environment.
