I decided not to use Bacula because the maintenance of the MySQL db got really out of hand backing up a filesystem that had over 10million files on it, the db grew 7gb+ additionally for every full backup of this FS I had in the retention period.

Soft error count since last status=0 General status bits on (41010000): BOT ONLINE IM_REP_EN Dustin -- the output of the hardware I had provided initially was from the 'lshw' utility.
