[TriLUG] SATA and Linux RAID

[jbrigman at nc.rr.com]

Dean - Do both, if you can. As cheap as the 250GB SATA drives are, put 
two in a mirror in the system and use one to do the nightly backup to. 
Mirroring gets you protection against drive failure, and the nightly 
backup gets you a 24 hour window of protection against deleted data. 

Alan was right about rsync: it's a great way to do nightly backups, 
you can do incremental rsync and speed things up dramatically over a 
full nightly dump.
