I have multiple computers for which I would like to keep files in sync.
I also happen to have a account on DreamHost as a webhosting company. There hosting plan includes a 50GB backup user so why not take advantage of that.
My first toughts was to use the very useful tool Unison, which I used at other occasions. The problem with the DreamHost backup user is that this account is limited to use only ftp, sftp, rsync and/or rdist. So Unison was out of the question.
So starting to look at rsync it was clear that rsync could not provide the same functions as Unison.
What I ended up using was this small script.
