So far in this walkthrough, git-annex has been used with a remote
repository on a USB drive. But it can also be used with a git remote
that is truly remote, a host accessed by ssh.
Say you have a desktop on the same network as your laptop and want
to clone the laptop's annex to it:
desktop# git clone ssh://mylaptop/home/me/annex ~/annex
desktop# cd ~/annex
desktop# git annex init "my desktop"
Now you can get files and they will be transferred (using `rsync` via `ssh`):
desktop# git annex get my_cool_big_file
get my_cool_big_file (getting UUID for origin...) (from origin...)
SHA256-s86050597--6ae2688bc533437766a48aa19f2c06be14d1bab9c70b468af445d4f07b65f41e 100% 2159 2.1KB/s 00:00
ok
When you drop files, git-annex will ssh over to the remote and make
sure the file's content is still there before removing it locally:
desktop# git annex drop my_cool_big_file
drop my_cool_big_file (checking origin..) ok
Note that normally git-annex prefers to use non-ssh remotes, like
a USB drive, before ssh remotes. They are assumed to be faster/cheaper to
access, if available. There is a annex-cost setting you can configure in
`.git/config` to adjust which repositories it prefers. See
[[the_man_page|git-annex]] for details.
Also, note that you need full shell access for this to work --
git-annex needs to be able to ssh in and run commands. Or at least,
your shell needs to be able to run the [[git-annex-shell]] command.
For details on setting up ssh remotes, see the
[[tips/centralized_git_repository_tutorial]].
