I screwed up one of my repositories, so I decided to start from clean slate. I have a remote bup repository that has all of my previous repository data. Now, I want to get it back. How I can do this?

If your bup repository is a git-annex special remote, it contains only the contents of annexed files, but not the rest of the git repository data (no filenames, no pointers to git-annex keys, etc).
Also, the files in it may be encrypted in a variety of ways depending on how you set up that git-annex special remote. If encryption was used, most likely it needs information that was stored in the git repository to decrypt it.
So, your best bet is to restore your git-annex repository from a backup or a clone of that repository. Then you can just
git annex enableremotethe bup special remote and usegit-annex getas usual. If you didn't have a backup or a clone of the git-annex repository, then important information is lost.Without the git-annex repository, you can manually get the contents of the files from the bup repository. In the bup repository, run
git branch; this will print out the names of all the git-annex keys that were stored there. Then you can usebup jointo extract the content of each key:Without the git-annex repository, there's no record of what the filename was, but you can extract the content this way.
But, if the key names start with "GPG" the the data is stored in bup encrypted and you are probably out of luck (although if you used encryption=pubkey when setting up the bup special remote, you can use gpg to decrypt the files after
bup join).
