Backup Advise

[glennbtn]

Hi All

I have a 1tb ssd in my proxmox and use a synology to store the lxc data as I have 14Tb on there. I have come accross the issue when backing up /mnt/pve/netdrive-nfs/dump/tmp/vzdumptmp5054: Cannot open: Permission denied

Now the onboard SSD is not big enough to house a backup. If I set the temp directory in /etc/vzdump.conf to the SSD, does the whole backup go to the ssd before the synology on NFS? Bit confused how it works as can't hold that sort of data on there.

Thanks

What command are you using exactly to perform your backup? Did you use the GUI? Please provide the full log using [code]your log[/code]. In addition, please give us the output of the following commands:

cat /etc/pve/storage.cfg
cat /etc/vzdump.conf
ls -lah /mnt/pve/netdrive-nfs/dump

Please review the permissions of your NFS. Additionally, you can try to backup a smaller container to the NFS but using something different as tmpdir.
