Whats going wrong?

Free space on harddrives are enought.

Whats going wrong?

You can't copy the snapshot into the snapshot - that is an endless loop!

Please use another disk to save the result (--dumpdir).

Thanx for answer. I have setup the backup over the web interface. I have a second hdd in the proxmox server. Can i setup the second hdd as a fixed "snapshot drive" ?

LVMs snapshots are always on the same volume group as the original volume - you cannot change that.

But you can mount the second hdd somewhere and use the --dumpdir option (configure in /etc/vzdump.conf - see 'man vzdump')
