Hi!
Using bup for storing seems a good idea to save space, but I still have a problem when trying to copy files to my local git repo.
I have two partitions:
- /Data (NTFS)
- / (ext4)
I turned the directory /Data/Audio into a git-annex repo, and cloned it into /home/me/AudioClone.
I added the remote bup to AudioClone by doing:
git annex initremote mybup type=bup encryption=none buprepo=
But when I try to copy some files that I have previously got by "git annex get" by doing:
[~/AudioClone]$ git annex copy someartist/somealbum --to mybup
it fails and tells me:
copy Order To Die/01 Morituri Te Salutant.flac (to mybup...)
fatal: Cannot lock the ref 'refs/heads/WORM-s7351771-m1318841909--01 Morituri Te Salutant.flac'.
Traceback (most recent call last):
File "/usr/lib/bup/cmd/bup-split", line 170, in <module>
git.update_ref(refname, commit, oldref)
File "/usr/lib/bup/bup/git.py", line 835, in update_ref
_git_wait('git update-ref', p)
File "/usr/lib/bup/bup/git.py", line 930, in _git_wait
raise GitError('%s returned %d' % (cmd, rv))
bup.git.GitError: git update-ref returned 128
for each file, **except for the album cover file**, which is a simple JPG that bup doesn't try to split. This one gets copied nicely but the big FLAC files don't.
I tried to restart my session, in case bup adds my username to a group or something.
(I'm using Ubuntu 11.10)
