Starting the assistant version 5.20140613 on my repository (~60GB), it performed a merge with an offline-repository, deleting a large part of the files. Since the repo is in direct mode, I cannot do a git revert. The other repo is not available anymore
Any way of getting them back? Also, du shows me that the .git/annex/objects folder has approximately the size of my repo before the incident.
All your files are still there..
You can either use
git annex indirectto switch to indirect mode and thengit revert, or you could git clone the repo to someplace else, do the revert there, and then rungit annex syncin first the clone and then in the direct mode repo to sync the reversion back.
