I have one b&r repository as target for testing endpoint backups. Repository is encrypted.
Only two disk from 24 is showed as encrypted in b&r console "disk (encrypted)". Why not all 24? try several times rescan repository
ddpeval tool show only 3.8gb saving for total 24vbk, 36vib files, total .1.45tb.
Repository have disabled "align backup file data blocks" but this is not relevant in this test? Option "use per-vm backup files is checked.
PS C:\Users\user> ddpeval "f:\Endpoint Backup"
