All you need is a clone of the repository that is not using direct mode.
(The assistant normally sets up repositories using direct mode.)
So either stop the assistant and run "git annex direct" inside ~/annex,
or `git clone` the backup repository to a temporary location.
In that clone, you can use regular git commands to check out past versions
of the tree. Inside such a checkout, you can use `git annex get` to get any
of the files in that checkout from your backup repository or wherever the
content of the file has been stored.
For example, using the git-annex repository that I use to publish builds of
git-annex:
# git clone https://downloads.kitenet.net/.git/ downloads
# cd downloads
# git log --stat git-annex/linux/current/
(shows a whole lot of past versions of files in that directory)
(I decide I want one from a few months ago)
# git checkout 81a0d7d
HEAD is now at 81a0d7d... publishing git-annex 5.20150731
# git annex get git-annex/linux/current/git-annex-standalone-i386.tar.gz
get git-annex/linux/current/git-annex-standalone-i386.tar.gz (from origin...) ok
Your backup repository can be used the same way.
Deleted and old versions of files will be retained in it, as long as the
assistant was able to send them to the backup repo in the first place
before they got deleted or modified. When direct mode is used, if you
change a file before it gets copied to the backup, its old contents are gone
for good. To avoid that and make sure that all annexed files always get
backed up, switch your ~/annex to use indirect mode.
