      We've just merged a potential fix, if you could try it that would be great 🙂

        @julien-f Unfortunately, my experience with this latest fix has not been a positive one --

        • GUI is unresponsive (spinning graphic only)
        • Backup job kicks off improperly (scheduled for midnight)
        • Weekly XO report has been generated multiple times
        • Timeout show in logs

                @julien-f Much better, thanks!

                Only minor issue I observed is that there appears to be a minute delay between the time the job starts and the UI is updated to reflect that the job is active.

                  @Danp Probably unrelated, do you mind creating an issue on GitHub for this? We'll investigate.

                        Hi

                        I had exatly the same problem when I upgrade one of my four server from xenserver 7.1 to xcp-ng 8.0, one backup failed with error: job already running and the other finish normaly later!

                        I upgrade Xo from 5.51 to 5.54 and it's Ok for this problem BUT I have a new problem, the cold backup to NFS and the Continuous replication to a Xcp-ng 8 server are REALLY slow !! One exemple:

                        I try to upgrade debian OS, upgrade VM (4cpus 3Go ram) but same problem for the moment

                        Thanks in advance

                        Edit: I do a manual test by copy an iso of 2G locally on the virtual machine Xen orchestra, to the same connected NFS for backup, and the performance is normal, 10 seconds for 2Go, it seems to be a problem with Xen orchestra system backup?
