I use rsync to basically make a copy / mirror of /home directory from one 
machine to another. This should do it:

rsync -avzu -e ssh user a net:/home /backup_dir/

If you run that from a1.net, for the first time run, this will copy the home 
directory of a.net to /backup_dir/ in a1.net. Subsequent run will only copy 
the new files, or updated files in a.net /home directory. That's the beauty 
of rsync.

Make sure 'user' has permission to read /home, so you may want it to login as 

You can also set that as a cron job, but you may need to use SSH key so that 
you don't need to login, here's how (there are many other similar HOWTO):

Right now I'm taking a look at mondo (mondorescue.org), planning todo it 
tomorrow. It seems to be a good solution for regular backup.

Hope that helps.
