Backup on encrypted, exchangable disks

[dave]

Hi,
in small environments with a single host, we often use https://github.com/NAUbackup/VmBackup for backup to USB Disks encrypted with LUKS.

This basically does a "xe vm-export" and works well.

We wrap this into a small shell script, that identifies the currently attached USB drive, mounts it, backups, and then unmounts it.

Everything is handled by the hosts itself.

Now i was thinking about using a XO VM fur such Tasks, the following questions came into my mind:

• What would be the best way to expose the attached USB drives to a XO VM? NFS, USB Passthrough or udev SR or such?

• How to configure XO for Backup Remotes that get Plugged or unplugged?

• What backup Strategy would be best suited for such a Task?
