There should be a backend where the file content is stored.. in a git repository!

This way, you know your annexed content is safe & versioned, but you only have to deal with the pain of git with large files in one place, and can use all of git-annex's features everywhere else.

Speaking as a future user, do very, very much want. -- RichiH

Might also be interesting to use bup in the git backend, to work around git's big file issues there. So git-annex would pull data out of the git backend using bup. --Joey

Very much so. Generally speaking, having one or more versioned storage back-ends with current data in the local annexes sounds incredibly useful. Still being able to get at old data in via the back-end and/or making offline backups of the full history are excellent use cases. -- RichiH

done, the bup special remote type is written! --Joey

Yay! -- RichiH
