Please describe the problem.
git annex export --fast main --to <remote> deletes existing files on a rsync ssh remote. My mental model was that --fast usually instructs git-annex to not do (slow) network connections.
My use-case for a fast export is to add an existing ssh-accessible non-git directory on a HPC system as a potential data source for a git-annex repository. The repository has additional information like how to retrieve the files from a third-party, while the directory on HPC only has the files (which were downloaded without git-annex involvement already). My plan was to add the directory as an exporttree remote, make git-annex think that the current main branches tree should be available there via the fast export, and then do a git annex fsck --from <remote> to discover what's actually there. Obviously it is very undesirable to loose those files on export then.
From what I understand I could hack around this if I graft the tree into the git-annex branch and write export.log myself, but I am wondering if I am just encountering a bug and this should work the way I wanted it to.
What steps will reproduce the problem?
- Create a git-annex repository and add some files
- Create a plain directory with (a subset of) the same filenames in the repository
- Add this directory as an rsync export remote:
git annex initremote <remote> type=rsync rsyncurl=<host>:<path> exporttree=yes encryption=none git annex export --fast main --to <remote>- Observe files being deleted on the remote
