Backing up with rsync
Rsync copies data to another directory, another disk volume, or another machine. It only copies what needs to be copied; that is, if a file hasn't changed since the last time you backed it up, rsync won't bother copying it again. Even better, if only part of a large file has changed, rsync only copies those bytes.
I don't see any point in calling rsync from Applescript, but if you must, you can. I'd just write a Terminal bash script. For my system, it looks like this:
cd $HOME rsync -av -e ssh . firstname.lastname@example.org:ibook
The 192.168.3.237 is a Linux server. I'm using ssh as the transport protocol. This backs up my home directory to the "ibook" directory under "tonyl"'s account on the Linux box.
If I were backing up to another directory or drive here, I might instead do:
cd $HOME rsync -av . /Otherplace
If I were concerned about including resource forks, I'd add "-E":
rsync -aEv . /Otherplace
Some like to use "-aEv --delete" to remove files on the archive that no longer exist here. I deliberately do not do that. I have plenty of space on the Linux box.
If you must do this with Applescript, use "do shell script", but it's really silly to waste that overhead.
