Your history is toast. Stop burning cycles. Lock your working server, Take clean working copies of the important branches if you can get them, the clean working copies, import them to a new server, and start with a much lighter working repository.
And *stop* putting binaries in the same repository as source code. History is usually much more important for source, binaries harshly burden all source control systems, and even the smallest errors corrupt them irretrievably. If you *must* store binaries, be sure to commit them in entirely distinct commits from the source code, to avoid precisely this problem, Sent from my iPhone
