I have a large repository that is backed up to hubiC with the special remote that I wrote. When I created this repository I used the WORM backend. But as I have some duplicated files I'd like to migrate to SHA256E to avoid storing them twice. However, when migrating a file, its location on the remote is not kept:
% git annex whereis "2015-07-25 12.28.16.jpg" whereis 2015-07-25 12.28.16.jpg (2 copies) 23fa590d-682d-43be-9851-8ba47186d763 -- [hubic] f6642b89-2a0f-4788-8e13-be540fdfec58 -- baldr [here] ok % git annex migrate "2015-07-25 12.28.16.jpg" --backend SHA256E migrate 2015-07-25 12.28.16.jpg ok (recording state in git...) % git annex whereis "2015-07-25 12.28.16.jpg" whereis 2015-07-25 12.28.16.jpg (1 copy) f6642b89-2a0f-4788-8e13-be540fdfec58 -- baldr [here] ok
Is there any way to store in the git-annex branch that migrated files are still available on remotes without having to re-upload all of them? hubiC is quite slow and I don't really want to re-upload 90 GB from a DSL connection…
Or would it be possible to add something in the special remote protocol to "move" a key without re-uploading it?
