Please describe the problem.

I would like to make multiple copies of precious data and I would like these copies to run simultaneously to minimise the elapsed time taken. Ideally, I would like to specify multiple --to options to git annex copy. I have tried running multiple processes simultaneously but these start to fail with lock contention on .git/config.

What steps will reproduce the problem?

Running four simultaneous git annex copy --to= commands.

What version of git-annex are you using? On what operating system?

OS is debian jessie, using git-annex-standalone from NeuroDebian.

Please provide any additional information below.

What I have is a python script and its output which I can't imagine is that helpful, but if you want it I'll upload it.

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Usng it regularly and like it - many thanks. This is a wishlist item, not a bug, as far as I'm concerned.

done, no response to my question... --Joey
