Simple is good.  I also use 3 external eSATA drives.  I haven't tried 
this yet but I was considering using a cron job to run the command line 
command that generates a large tar file of the backup.  I had a complete 
hard disk failure 7 months ago and this was how I moved the data from 
the backuppc machine to the new replacement drive on my server.  The 
only thing I would have to do is remember to cycle the disks.

Any comments on pros/cons to this method?

Thank you,
