Hi Alexandre,

I had the exact same issue:

https://forum.proxmox.com/threads/partial-sync-job-pre-prune.106441/

Here is the bugzilla:

https://bugzilla.proxmox.com/show_bug.cgi?id=3701

So no AFAIK there's no way to do a partial sync. A tool to sync a
specific backup (instead of a group) and a bit of scripting would do
the job.

Sincerely,

Laurent
