Git supports pushing via the ssh protocol, and since you have already
set up the ssh connection, the rest is rather simple.

On the backup machine, create a bare repository:

$ mkdir -p /path/to/backup-repo.git
$ cd /path/to/backup-repo.git
$ git init --bare

Then you can push from your work machine:

$ git push --all ssh://[user@]<backup>/path/to/backup-repo.git
$ git push --tags ssh://[user@]<backup>/path/to/backup-repo.git

where "<backup>" is the hostname of your backup machine, and "user" is
your login name there (which you can usually omit).  You probably also
want to add the backup repository as a remote, so that you do not have
to write the long URL every time you push.
