Hello,

I am not able to restore backups from my NFS share (Synology NAS) and I really do not know what to do anymore. It all started with my server randomly crashing without obvious reason or hint in the log files. The problem also occurred during the backup process, but not every time, so that when I tried it three times, I was able to do one backup. So I decided to do a fresh installation of Proxmox. With really having changed nothing, only updated proxmox, added the nfs share and created a zfs raid 1 for two storage hdd's I am still not able to restore my backup of my nextcloud container. The container is nearly 4TB in size. I am able to restore smaller containers or vm's in 9/10 cases, but not every time and I think the underlying issue is the same, as I also receive the connection timeout error. During the restore process of the containers backup file, at some point sooner or later, I get a connection timeout error and the server is not reachable anymore. I can only reboot the server, nothing else works anymore and the NAS also shows no upload anymore.

What I have tried so far:
  1. Fresh installation of Proxmox (several times)
  2. New HDD's, SSD's and RAM
  3. HPE sent me a new Motherboard
  4. Tried Proxmox 7.3, 7.2 and 6.x?
  5. Tried it with all available NFS versions
  6. Firmware upgrades and downgrades
  7. Installed Ubuntu on the server and moved the ct zst file from the NAS to Ubuntu - worked without a problem

Please if anyone has an idea what to do, I am going mad!!!
