      Hi

        XFS? That might be the reason why, I don't remember that we support XFS for file level restore.

          Here is no XFS 😉

            @badrAZ or someone else of XO team will try to reproduce the issue. They are under heavy lot for a bunch of new exciting features, so it might take time to test.

                    I tested this functionality on ext4 and xfs and it works for me.

                    6dab6902-06e6-4e59-a70e-1dd1b56704aa-image.png

                    Unfortunately, i need to reproduce this issue in our lab to be able to investigate more.

                          @othmar Install XOA in trial mode and then retest to see if the issue is present with it.

                              It's same here. Problem is in community version and in xoa trial.

                                There's obviously something different between the VMs you use and ours for tests. Would you be able to provide a VM export so we can deploy it on our side, backup it and see why file restore doesn't work?

                                  I am seeing the same issue with LVM restores. Exists between Trial and Community editions.

                                    Do you have a VG using multiple PVs?

                                      That one does not. I assumed that was the case for another one that had the issue, and working to move the VMs to VHDs that are not on LVM.

                                        Same problem on XOA latest?

                                        edit: ping @julien-f and/or @badrAZ

                                          Both the built community edition and the XOA appliance seem to have this issue.

                                            A little more info... I'm also having this problem, but it seems only non-Linux file systems have a problem on my side. Let me know if I can run/supply anything on this side that might be useful?

                                            Debian, CentOS and Ubuntu files recoveries are all fine, but Windows Server, Windows 10 and pfSense drives are throwing the same error others have posted previously. Error seems to start a step earlier than what has been previously suggested though?

                                            Server is XO Community on Debian, NFS remote (Synology NAS) all LVMs I think.

                                            Selecting backup date is fine. Selecting drive from the backup gives this error:
