Does anyone know of good solutions to this issue?

   I'm basically running off a raspberry pi right now.  I don't have a lot
   of finances.  I do have a number of external drives, but they tend to
   break faster than I can recover my files from them, resulting in a big
   queue of "to image/analyse" .
   I've been using git-annex, but I'm running into the issue that `git
   annex repair` seems to wipe my git history when I run into object
   corruption.
   What kinds of solutions exist already for large hash-addressed data
   integrity with history, that will work when the storage media are
   failing quickly?
