“At last here are the final two parts of this series. Today we
learn how to tell rsync which files to include or exclude, set up
passwordless login on the backup server, and safely test
everything. Tomorrow we put it all together and completely automate
wakeup, backup, and shutdown.

“The first three parts:
Antec 300 Computer Case Quick Review
Arch Linux Backup Server– Headless Administration
Linux Backup Server: Remote Wakeup, Automatic Shutdown

“Prequisite: SSH Everywhere

“You need SSH already set up, tested and working on all your
computers. At a minimum you need the SSH daemon running on the
backup server, user accounts on the server, and logins tested from
the client PCs.

“Rsync Backup Script

“While rsync has a huge number of options, there are just a few

installed on all the PCs that I want backed up. My backup server is
named “backup_server”, and why don’t we call this backup script
“backup_script”.
