Yes, I commend you for going for the command line tools like that.
Tackling rsync is no slouch by any means. Frankly, I can rarely
remember all the command line options for rsync and have to either
constantly look at the man page or previous working examples. I would
also create little one or two line shell scripts with these commands
in them and then just run the script each month or whenever. That's
why Joseph's script example had the '$1' and '$2' thingies in there.
those can then be substituted by just putting in the names of the
paths and run the script. Also, I believe Joseph's example included
the --delete option. However, I don't recall what is actually being
deleted at that point. Might wanna check to be sure there.
Also, if you get more adventuresome in the future, you might wanna
look at a program called rdiff-backup. It uses rsync under the hood
and allows for optional inclusions and exclusions like rsync does but
allows for staging different backup sets over time and yes, each
subsequent backup is just the differences. Plus then if you need to
restore a file from the most recent backup, it is merely a mirror of
your current environment so you can just copy the desired item to be
restored. But rsync is a good start and an excellent way to sync up
two computers over a network too.
