If you’re a regular reader, you might have noticed that I’ve been on a quest for the perfect backup program, and ended up writing my own encryption layer over bup.
While writing encbup, I wasn’t very satisfied with having to download the entire huge archive just to restore a file, and still wished that I could use EncFS together with rdiff-backup to have true remote-mountable, encrypted, deduplicated, versioned backups.
Trying obnam again (spoiler: it’s still pretty slow), I noticed that it included a
mount command. Looking at it, I discovered fuse-python and fusepy, and realized that writing a FUSE filesystem in Python is pretty much trivial.
The astute observer will have already realized where I’m going with this: I decided to write an encrypted filesystem layer in Python! This layer would be very similar to EncFS, with a few crucial differences:
