I've had my BackupPC installation backing up to an external encrypted
USB2 hard-drive for a few months now. Works great. I'm not using
cryptoloop, but instead using DeviceMapper.
I followed Ubuntu's Encrypted File System Howto
(https://wiki.ubuntu.com/EncryptedFilesystemHowto) to set up the

Option 1: symlink /var/lib/backuppc to your backup drive.
Option 2: mount your backup drive to /var/lib/backuppc

Worth noting, I use a Maxtor USB2 hard drive for BackupPC. Whenever my
system gets rebooted, the hard drive doesn't automatically mount, and
as a result backuppc can't find /var/lib/backuppc, so BackupPC doesn't
start either.
I think Ubuntu tries to mount hard drives before detecting USB
devices.
