I can sort of agree with the RAID issue for a hosted setup, but at home after trying both software RAID 1 and hardware RAID 1, I much prefer having a secondary disk that I can rsync data to, thus being able to keep more multiple revisions instead of only duplicating the current data on the disk. backuppc is good at this, as well as other customized rsync/rsnapshot scripts. Worse case scenario I have to reinstall my OS, but losing everything is less likely.
I plan on updating this as things move forward. Thanks for the kind words.
