      I'm running xo-server 5.74.0 community edition.
      I have a delta back up job set up as follows for 3 VMs:
      Full backup interval 2
      Weekly Backup
      Backp Retention 3
      SMB remote

      When I run the backup initially it will succeed on subsequent runs it will have the following errors.

      VM 1 Error:

      I have other Full backup jobs that run sucessfully before it which writes to the same target SMB remote.

      What could be the problem?

          @olivierlambert OK so now I'm testing on a XOA trial with the same remote and back up settings and I still get this error.

          I have 3 VMs, the initial run for the full back up runs fine.
          Then I ran the backup manually again, this time it's the delta backup and I get the following error for one VM with a 200GB disk. The delta back up for the other two were fine.

              I need to take a look at the raw log to understand what's going on here (there is a button to download it at the top of the run status modal).

              Usually EINVAL indicates a system error in the communication between the XOA and the remote.

                  @deoccultist Not much I can add there, it looks like a system error between your XOA and the remote.

                  1. What kind of remote are you using?
                  2. Does this happen often?
                  3. Have you tried restarting xo-server or the OS?
