NAME
git-annex copy - copy content of files to/from another repository
SYNOPSIS
git annex copy [path ...] [--from=remote|--to=remote]
DESCRIPTION
Copies the content of files from or to another remote.
OPTIONS
--from=remote
Copy the content of files from the specified remote to the local repository.
Any files that are not available on the remote will be silently skipped.
--to=remote
Copy the content of files from the local repository to the specified remote.
--to=here
Copy the content of files from all reachable remotes to the local repository.
--jobs=N
-JN
Enables parallel transfers with up to the specified number of jobs running at once. For example:
-J10
--auto
Rather than copying all files, only copy files that don't yet have the desired number of copies, or that are preferred content of the destination repository. See git-annex-preferred-content(1)
--fast
When copying content to a remote, avoid a round trip to check if the remote already has content. This can be faster, but might skip copying content to the remote in some cases.
--all
-A
Rather than specifying a filename or path to copy, this option can be used to copy all available versions of all files.
This is the default behavior when running git-annex in a bare repository.
--branch=ref
Operate on files in the specified branch or treeish.
--unused
Operate on files found by last run of git-annex unused.
--failed
Operate on files that have recently failed to be transferred.
--key=keyname
Use this option to move a specified key.
file matching options
The git-annex-matching-options(1) can be used to specify files to copy.
--batch
Enables batch mode, in which lines containing names of files to copy are read from stdin.
As each specified file is processed, the usual progress output is displayed. If a file's content does not need to be copied or it is not an annexed file, a blank line is output in response instead.
Since the usual output while copying a file is verbose and not machine-parseable, you may want to use --json in combination with --batch.
--json
Enable JSON output. This is intended to be parsed by programs that use git-annex. Each line of output is a JSON object.
--json-progress
Include progress objects in JSON output.
--json-error-messages
Messages that would normally be output to standard error are included in the json instead.

Hi,
I want to back up all my files including previous versions on an external drive. I’ve tried these two commands – both of them exited instantly without producing any output:
Commenting on a man page is not the right way to report a problem. File a bug report.
FWIW, copy --all works fine in my tests. Of course, there are certianly situations where it copies nothing. Eg, if there are no files with ontents in the repository for it to copy.
If you run
git annex copy --from slowremote1
in one terminal and at the same time rungit annex copy --from slowremote2
in another terminal, the two processes will cooperatively get the files, spreading the load amoung the remotes. This works because git-annex avoids downloading a file if the same file is already being downloaded by a different process.
