NAME
git-annex-sync - synchronize local repository with remotes

SYNOPSIS
git annex sync [remote ...]

DESCRIPTION
This command synchronizes the local repository with its remotes.

The sync process involves first committing any local changes to files that have previously been added to the repository, then fetching and merging the synced/master and the git-annex branch from the remote repositories, and finally pushing the changes back to those branches on the remote repositories. You can use standard git commands to do each of those steps by hand, or if you don't want to worry about the details, you can use sync.

The content of annexed objects is not synced by default, but the --content option (see below) can make that also be synchronized.

Note that syncing with a remote will not normally update the remote's working tree with changes made to the local repository. (Unless it's configured with receive.denyCurrentBranch=updateInstead.) However, those changes are pushed to the remote, so they can be merged into its working tree by running "git annex sync" on the remote.

OPTIONS

[remote]

    By default, all remotes are synced, except for remotes that have remote.<name>.annex-sync set to false. By specifying the names of remotes (or remote groups), you can control which ones to sync with.

--fast
    Only sync with the remotes with the lowest annex-cost value configured.

--commit, --no-commit
    A commit is done by default (unless annex.autocommit is set to false).

    Use --no-commit to avoid committing local changes.

--message=msg
    Use this option to specify a commit message.

--pull, --no-pull
    By default, git pulls from remotes. Use --no-pull to disable all pulling.

    When remote.<name>.annex-pull or remote.<name>.annex-sync are set to false, pulling is disabled for those remotes, and using --pull will not enable it.

--push, --no-push
    By default, git pushes changes to remotes. Use --no-push to disable all pushing.

    When remote.<name>.annex-push or remote.<name>.annex-sync are set to false, or remote.<name>.annex-readonly is set to true, pushing is disabled for those remotes, and using --push will not enable it.

--content, --no-content
    Normally, syncing does not transfer the contents of annexed files. The --content option causes the content of files in the work tree to also be uploaded and downloaded as necessary.

    The annex.synccontent configuration can be set to true to make content be synced by default.

    Normally this tries to get each annexed file in the work tree that the local repository does not yet have, and then copies each file in the work tree to every remote that it is syncing with. This behavior can be overridden by configuring the preferred content of a repository. See git-annex-preferred-content(1).

    When a special remote is configured as an export and is tracking a branch, the export will be updated to the current content of the branch. See git-annex-export(1).

--content-of=path -C path
    While --content operates on all annexed files in the work tree, --content-of allows limiting the transferred files to ones in a given location.

    This option can be repeated multiple times with different paths.

--all -A
    This option, when combined with --content, makes all available versions of all files be synced, when preferred content settings allow.

    Note that preferred content settings that use include= or exclude= will only match the version of files currently in the work tree, but not past versions of files.

--jobs=N -JN
    Enables parallel syncing with up to the specified number of jobs running at once. For example: -J10

    When there are multiple git remotes, pushes will be made to them in parallel. Pulls are not done in parallel because that tends to be less efficient. When --content is synced, the files are processed in parallel as well.

--resolvemerge, --no-resolvemerge
    By default, merge conflicts are automatically handled by sync. When two conflicting versions of a file have been committed, both will be added to the tree, under different filenames. For example, file "foo" would be replaced with "foo.variant-A" and "foo.variant-B". (See git-annex-resolvemerge(1) for details.)

    Use --no-resolvemerge to disable this automatic merge conflict resolution. It can also be disabled by setting annex.resolvemerge to false.

--cleanup
    Removes the local and remote synced/ branches, which were created and pushed by git-annex sync.

    This can come in handy when you've synced a change to remotes and now want to reset your master branch back before that change. So you run git reset and force-push the master branch to remotes, only to find that the next git annex merge or git annex sync brings the changes back. Why? Because the synced/master branch is hanging around and still has the change in it. Cleaning up the synced/ branches prevents that problem.
