Hello guys, I have TrueNas as a VM and i added the storage as NFS to proxmox and i installed LXC on that storage. i had auto backup as snapshot everything worked fine but i wanted to redo it so i deleted the LXC and removed the truenas storage and remounted it and tried to make another LXC now i keep getting:
Code: 
INFO: starting new backup job: vzdump 108 --notes-template '{{guestname}}' --remove 0 --node dayroxy --mode snapshot --compress zstd --notification-mode auto --storage TrueNasStorage

INFO: starting first sync /proc/1858/root/ to /mnt/pve/TrueNasStorage/dump/vzdump-lxc-108-2024_05_07-04_02_29.tmp

Although it used to work and i had more than 30 backups before while having snapshot on, also if i use tmp/zv it will work but problem is i wanted as the default without using tmp/zv any idea what it could be / how to fix it?

Hi,

snapshots are not supported on NFS storage with RAW disks:
https://pve.proxmox.com/wiki/Storage

You could change/migrate your 108 disk to a qcow2 format for snapshot support.

Hey thank you! yeah i found a way around if i change the tmp zv directory but im confused as of why it used to work and all of the sudden it stopped also how can i change from raw to qcow2 via gui if i may ask?
Thank you so much for your reply!
