[[!meta title="what git-annex is not"]] * git-annex is not a backup system. It may be a useful component of an [[archival|use_case/bob]] system, or a way to deliver files to a backup system. For a backup system that uses git, take a look at [bup](http://github.com/apenwarr/bup). * git-annex is not unison, but if you're finding unison's checksumming too slow, or its strict mirroring of everything to both places too limiting, then git-annex could be a useful alternative. * git-annex is more than just a workaround for git limitations that might eventually be fixed by efforts like [git-bigfiles](http://caca.zoy.org/wiki/git-bigfiles). * git-annex is not some flaky script that was quickly thrown together. I wrote it in Haskell because I wanted it to be solid and to compile down to a binary. And it has a fairly extensive test suite. (Don't be fooled by "make test" only showing a few dozen test cases; each test involves checking dozens to hundreds of assertions.)
