That's a regular theological debate round here, and some people will say yes, and others an emphatic no. I'm personally happy with ZFS raidz, others prefer UFS + mirroring + journalling. Speaking with far too many years of experience as a sysadmin, no single backup solution is ever truly adequate. You want off site backups as well as on site. For the off site backups, take a look at tarsnap: http://www.tarsnap.com/ -- "Although the wombat is real and the dragon is not, few know what a wombat looks like, but everyone knows what a dragon looks like." -- Avram Davidson, _Adventures in Unhistory_
