Hello word,
I have a proxmox 8 cluster with no problem. I can backup my VM (windows, linux...) on NFS or Proxmox backup server with no problem.
Yesterday i created a new Debian 12 VM with one ext4 disk --> No problem. Backup was normal.
I added a second disk on my VM, and i formatted this second disk with ZFS (because i want AUTOEXPAND fonctionnality), and i saw that the backup are extemily slow in write action. (240 B/s !!)
I dont see anything special in VM (no cpu or memory saturation). I can write data on it with SAMBA normaly.
Any idea why disk with ZFS have a problem on backup ?
best regards
GE

It's only the fact when you backup a disk of16 TB, the 1% achievment take 9 minutes to arrive, and i had the bad perception than the backup did not work well.
