Linux Back up questions. (Fedora C2)

1) Is there available software to back up data from a raid 1 to DVD using encryption?

2) I read adds from an Internet Backup ISP offering a compression of 10/1 using blowfish algorithm, how can I reach maximum compression and what ratio would that be?
3)  Could I obtain the result wanted in 1) and 2) using software from the distro and a script or commands?

4) How can I find the speed of DVD writing (figuring out how long the backups will take)?

Your advices are most welcome.
