More Backup Automation

This linux box also had a script (running at 2AM) that would ftp to my web server, retrieve all of the database dumps, download them, add a date stamp to the file name, and then copy the resulting files out to the RAID array. The entire process was automatic, transparent, and for a long time was quite robust.
