Delta restore to encrypted drive

[Keith Weisshar]

Why is delta restore not working when restoring to bitlocker encrypted drive.  It automatically does a full restore in windows re even if I leave delta restore checked when initiating restore from windows. After restore bitlocker is automatically disabled and I must encrypt the drive again.

I would assume its because of the encrypted drive. In order to image an encrypted drive any imaging application must do a forensic image; meaning that every block on that drive must get images and not just the used ones. The encryption prevents then from knowing what's used and what's not. As a result delta is not used.

Bitlocker encryption is still a little tricky unfortunately. There was a little discussion in December about the possibilities that might work to fix backups with Bitlocker:

@admin then picked up that discussion and said they're gonna look into it if possible:

Could be that Bitlocker will be supported fully in a future HBS update but currently that's not the case.

Yes, the current version still does not support BitLocker. We will conduct a technical feasibility analysis as soon as possible. If technically feasible, we will provide this feature in 2026.
