Hi,

I'm testing proxmox for a couple of months now and i'm very happy.
At the moment I have 3 disks, 2 internal and 1 usb-hdd.

I already set the backup job to backup the VM's from internal disk 1 to disk 2.
Now I want "something" to copy the backup-files from disk 2 to the usb-hdd when I connect it.

This because I plan to use this usb-hdd as an offsite-backup.
The usb-hdd will be connected every 2 weeks or so, so most of the time it will not be present for the system.

I think there are many ways to achieve this it all just depends on the amount of time you want to spend. I use ansible to do backup automatically but may not be worth the effort for you? idk... Can you just not like schedule a backup let us say every 2 weeks at 9 pm or something and insert that drive before?
And question, why not get the backup from the working vm/lxc rather than getting it from you backup? Reason i asked is this: what if your main backup is corrupted or something and you do not know about it? Then you do a backup of the corrupted data?
