1. Don't automount disks (dconf changes) this breaks backups
2. Rewrite the entire backup script to handle mounting, decrypting,
many use cases, etc
3. Update main.yaml to not create mount location for backup drive,
script will handle it
There were occasions where removing the backup drive would confuse luks
and prevent re-mounting. This fixes the issue by attempting to luks
close and open the drive before mounting, thereby correcting any issues
where the drive would stick.
