git-annex has a notion of "number of copies" of data that can be on
any number of remotes/backends, it's not automatically replicated.
Basically what it means is that I can do a "git annex copy -t library
*" where library can be a tahoe-lafs remote or rsync or whatever
git-annex is configured to use.  I can have copies of data on
different remotes/backends, i.e. one copy of data on tahoe-lafs and
one copy on an external hdd and git annex will keep track of it for
me.

I think git-annex does take abit of reading up before one understands
how its supposed to work and i miss used the term "data replication"
since i enforce replication of my data via shell scripts and cronjobs.
