Another [[special_remote|special_remotes]] that git-annex can use is a [[special_remotes/bup]] repository. Bup stores large file contents in a git repository of its own, with deduplication. Combined with git-annex, you can have git on both the frontend and the backend. Here's how to create a bup remote, and describe it. [[!template id=note text=""" Instead of specifying a remote system, you could choose to make a bup remote that is only accessible on the current system, by passing "buprepo=/big/mybup". """]] # git annex initremote mybup type=bup encryption=none buprepo=example.com:/big/mybup initremote bup (bup init) Initialized empty Git repository in /big/mybup/ ok # git annex describe mybup "my bup repository at example.com" describe mybup ok Now the remote can be used like any other remote. # git annex move my_cool_big_file --to mybup move my_cool_big_file (to mybup...) Receiving index from server: 1100/1100, done. ok Note that, unlike other remotes, bup does not really support removing content from its git repositories. This is a feature. :) # git annex move my_cool_big_file --from mybup move my_cool_big_file (from mybup...) content cannot be removed from bup remote failed git-annex: 1 failed See [[special_remotes/bup]] for details.
