@olivierlambert, Why would this issue be related to my NFS share? I can access the share without any problems, read and write operations work fine. Other NFS shares with multiple applications running are also functioning normally. I checked the XO logs and found the following: xo-server[679]: 2025-04-29T21:45:58.276Z xo:api WARN | backupNg.listFiles(...) [114ms] =!> Error: Command failed: vgchange -ay vg_iredmail xo-server[679]: File descriptor 22 (/var/lib/xo-server/data/leveldb/LOG) leaked on vgchange invocation.

Use '--activationmode partial' to override. To me, this looks more like an issue with file restore than the NFS itself. It seems similar to what's reported here: https://github.com/vatesfr/xen-orchestra/issues/7029 andrew64k created this issue in vatesfr/xen-orchestra open File level restoration not working on LVM partition #7029
