       git-annex-export - export content to a remote

       git annex export treeish --to remote

       git annex export --tracking treeish --to remote

       Use this command to export a tree of files from a git-annex repository.

       Normally files are stored on a git-annex special remote named by their
       keys. That is great for reliable data storage, but your filenames are
       obscured. Exporting replicates the tree to the special remote as-is.

       Mixing key/value storage and exports in the same remote would be a mess
       and so is not allowed. You have to configure a special remote with
       exporttree=yes when initially setting it up with git-annex-initremote(1).

       The treeish to export can be the name of a git branch, or a tag, or any
       other treeish accepted by git, including eg master:subdir to only export
       a subdirectory from a branch.

       Repeated exports are done efficiently, by diffing the old and new tree,
       and transferring only the changed files, and renaming files as necessary.

       Exports can be interrupted and resumed. However, partially uploaded files
       will be re-started from the beginning.

       Once content has been exported to a remote, commands like git annex get
       can download content from there the same as from other remotes. However,
       since an export is not a key/value store, git-annex has to do more
       verification of content downloaded from an export. Some types of keys,
       that are not based on checksums, cannot be downloaded from an export.
       And, git-annex will never trust an export to retain the content of a key.


              Specify the special remote to export to.

              This makes the export track changes that are committed to the
              branch. git annex sync --content and the git-annex assistant will
              update exports when it commits to the branch they are tracking.

       --fast This sets up an export of a tree, but avoids any expensive file
              uploads to the remote. You can later run git annex sync --content
              to upload the files to the export.

        git annex initremote myexport type=directory directory=/mnt/myexport
           exporttree=yes encryption=none
        git annex export master --to myexport

       After that, /mnt/myexport will contain the same tree of files as the
       master branch does.

        git mv myfile subdir/myfile
        git commit -m renamed
        git annex export master --to myexport

       That updates /mnt/myexport to reflect the renamed file.

        git annex export master:subdir --to myexport

       That updates /mnt/myexport, to contain only the files in the "subdir"
       directory of the master branch.

        git annex export --tracking master --to myexport

       That makes myexport track changes that are committed to the master

       If two different git-annex repositories are both exporting different
       trees to the same special remote, it's possible for an export conflict to
       occur.  This leaves the special remote with some files from one tree, and
       some files from the other. Files in the special remote may have entirely
       the wrong content as well.

       It's not possible for git-annex to detect when making an export will
       result in an export conflict. The best way to avoid export conflicts is
       to either only ever export to a special remote from a single repository,
       or to have a rule about the tree that you export to the special remote.
       For example, if you always export origin/master after pushing to origin,
       then an export conflict can't happen.

       An export conflict can only be detected after the two git repositories
       that produced it get back in sync. Then the next time you run git annex
       export, it will detect the export conflict, and resolve it.
