This backup is now used for the backup server.

Workstations back up to the backup server, which then backs up to disk.
Add revised workstation backup script.

Instead of going to a removable drive, they now backup pertinent files
(namely /etc) to the server. Note that all relevant user directories
are backed up via unison because it does double duty as an
asynchronous synchronization host between machines.
Revise backup script to be appropriate for the server.

This is the same as the original script "backup", except that it now
backs up /mnt/time_machine and /var.
Added periodic mysql backup script.

This will create periodic versions of the DB over time.
Add mysql backup for hiro.

This is a little interesting because mysql doesn't run all the
time. So, start it, back it up, then stop it.
Make etc backup less verbose.
Change server_backup to account for amahi not running an automounter.

 1. Manually mount the drive
 2. Make sure it succeeds.
