Note: The agaric git repository is not public, but this approach will work on your own server.
Stefan explained: copy your folders to your home dir on the server, cd to /srv/git and then run git clone --bare folder folder.git
cd ~
scp -r customhome ben@grassrootsconnection.org:~/customhome
On the server:
ben@server:/srv/git/agaric$ git clone --bare ~/customhome customhome.git
Initialized empty Git repository in /srv/git/agaric/customhome.git/
And don't forget!
