Thanks a lot, it's very good.
Be carreful with Promox 6.2.4, you must rename backup template filename's with this format "vzdump-qemu-xxx-yyyy_mm_dd-hh_mi_ss.vma.lzo" !
Else you will an error "TASK ERROR: ERROR: couldn't determine archive info from '/var/lib/vz/dump/vzdump-qemu-xpnology-ds918-62.clean.vma.lzo'.
I think it can help you
