Backup Ideas? (was Re: [geeks] Big Blue Smoke)

[Ryn]

I bougth 4 100GB IDE hard drive for backups at home. Each
drive is connected to a separate IDE controller. I created 2
200GB volumes (RAID 0) and run a dd job nightly to sync 
the two volumes. I wanted to use two volumes in case the 
data ever gets hosed on volume I. At least volume II is 
consistent as of my last backup.
