Deduplication factor always at 1.0

[MajorD]

Allo,

I have been using PBS for many months and I still see the Deduplication factor as 1.0.

I do not encrypt the backups and my VMs usually do not have snapshots. My datastore is using iSCSI volumes formatted with ZFS.

Should I expect better deduplication and if yes, what can I do to enable it?

Thanks.

Just to ask, more than one backup of each VM?

PBS automatically stores one copy of each unique chunk. It can actually be encrypted with the same key, and still work.

How are your GC and prune jobs set?
