If I enable the BitLocker device encryption on my disk, will it prevent Backblaze from backing up the disk?

Question

I use Windows 10 and Windows 11 24H2. I use Backblaze on it. If I enable the BitLocker device encryption on my disk, will it prevent Backblaze from backing up the disk?

Answer 1

Will BitLocker prevent Backblaze from backing up the disk?

BitLocker or VeraCrypt are full disk encryption (FDE) solutions, individual files are not encrypted. Backblaze works at the file system level (uploading individual files to the cloud), which requires a user to be logged into the system for it to function. Once a user logs into Windows, files are not encrypted, and BitLocker is unlocked.

Only Encrypted File System (EFS) would result in Backblaze uploading encrypted files. EFS nor BitLocker would prevent Backblaze from uploading a file into the cloud.

Answer 2

If I enable the BitLocker device encryption on my disk, will it prevent Backblaze from backing up the disk?

Based on https://redd.it/1hx0jq0 and Frank Thomas's comment, the answer is no: enabling the BitLocker device encryption on my disk will not prevent Backblaze from backing up the disk.
