      It looks like this issue occurs only when saving the backup to non-block storage. When saving to block storage ("Store backup as multiple data blocks instead of a whole VHD file: ON"), it does not, at least in my environment.

          I've had this issue for months with XOA and I've been told to not worry about it. Surely there is some way to recalculate the size of the VM backup to address this warning.

              The problem with this issue are not the message, but each incremental backup have a full size backup on small infrastructure (2/3To of VMs) this is a little problem, but on more larger (10To) it's beginning to be boring.

                @noritaka971 You sure it does always a full backup. I have this isuue for ages and looking at the backup protocols it's only doing the deltas, never a full backup when not supposed to.

                  I'm sure all my backup since this bug was appear in my system is Full backup, I don't know if the two issues are related but they appeared at the same time.

                    I am seeing this message, too. This is the first time I try out delta backups. I only did one backup so far, so this is a full backup. Storage is NFS.

                        I got bored by this "cleanVm: incorrect backup size" warnings. See https://github.com/vatesfr/xen-orchestra/pull/9637 So far, the fix works fine in our infra, no more warnings.

                        Keeping @florent and @olivierlambert in the loop.

                        jhoustek opened this pull request in vatesfr/xen-orchestra
