[SOLVED] Prune & GC & Verify on encrypted Backups and are the Backups still incremental

[Pablo1732]

Hello,
I want to store the backups of my PVE encrypted on my PBS. I am now wondering whether the pbs can still run a prune/verify/gc on the backups, since the pbs does not have an encryption key? My second question is whether the backups are still incremental at all?

yes

yes

Can it be that the encrypted backups are "not as incremental" as unencrypted ones?

 

[dcsapak]

to clarify a bit, the verify on the pbs only checks the crc checksum of the chunks not the content + chunk hash (for obvious reasons) so there is some downside to this,
but as the client does the incremental tracking, this still works

Ok,
Thanks for the explenation.
