      Not wanting to be a "me too" but I'm seeing exactly the same thing.

      Some VM's (unfortunately in my case large ones) and doing daily fulls rather than deltas.

      Backup taking 14 hours instead of 2 or 3.

      Similar etup to @S-Pam with nfs as the remote target.

          @pnunn @S-Pam If you use the sources, can you try to use this branch feat-add-debug-backup it's master with additionnal debug and a potential fix ( potential , because I can't reproduce it regularly in our lab)

          Then you can activate more debug by this

          [logs]
          # Display all logs matching this filter, regardless of their level
          filter = 'xo:backups'
          
          # Display all logs with level >=, regardless of their namespace
          level = 'debug'
          

          in your config file ( should be in ~/.config/xo-server/config.toml

            @florent unfortunately not. We use XOA.

              @s-pam it's a great choice 🙂
              If you can launch a backup , I can connect through a support tunnel and deploy the fix

              then you can launch the backup and we can celebrate the success of this fix

                Do you mean a second XOA? I already have a support ticket+tunnel open on it. Originally due to failed incremental backups, but now it includes this issue with full backups being made when they shouldn't.

                        We seem to experience the same issues. We are on commit d3071. It seems that xoa mislables the backups as well.
                        Even though we enforced a full backup through the schedule option, it is labled as a delta in the restore process menu.
                        The xoa backup "log" in the interface shows full as well instead of delta and the amount of data transferred is clearly a full.

                            I'm not sure if mine is an edge case or another "me too", but d3071 has partially fixed the always a full backup issue on my end.

                            I'm not sure exactly what's going on, but this morning I did wonder if it's to do with having two delta backup jobs (backing up to two different remotes), and whether something strange was happening with the snapshots between the two jobs.

                            For example, from my backup report for the first backup to a local NFS remote:

                            f2136443-ab35-4881-ab3e-8ac3f9c8bf31-image.png

                            Half an hour or so later, that same VM yields a full backup-sized transfer:

                            6f6bf1a5-418e-4d8f-9508-c45ce9014338-image.png

                            (Which, incidentally, I don't understand how it's a 3.33GiB transfer, when the VHD size on the SR is ~111MB and the output of df -h on the VM shows 1.8GB used. I'm confused!)

                            I'll roll onto feat-add-debug-backup and see what that yields!

                              @andrewreid XO team has released a new version 5.66.2 for XOA and new sources for the XO community that should fix most of the recent backup issue, so please update to latest and report back if needed.
