DVD-RAM has built-in hardware error checking and a 30 year shelf life. Its also 11 bucks for 9.4 gigs at compusa. I wouldn't use other RW fomats just because they are marketed better- they can't go the distance (-RAM has 100,000 rewrites,-RW jsut has 1000)
Another neat thing- linux thinks its a standard harddrive, you can do scheduled backups with a 1 line cron job.
An overview on the formats is here
