Is it possible to use LUKS on external backup drives with USB Backup plugin? I like the auto-mount and notification of USB Backup plugin a lot, up till now my backups are unencrypted, so I want to plug my drive into USB, maybe unlock the drive through SSH and then the normal procedere of USB Backup plugin should do its job. When done, drive should be unmounted as usual.
I not aware of the auto unlock options of LUKS, maybe there is an option which still provides enough security.
