Box Backup Filesystem

Box Backup is a great secure on-line backup system. It comes with a CLI (bbackupquery), but it's not as full featured as your favorite shell for browsing, and you must restore files before you can view them...

Conveniently, most operating systems that support Box Backup also support FUSE, which lets various data sources be viewed as native filesystems.

Combine the two and you get a very nice snapshot-filesystem capability...
