RAID is not
a backup solution.
Right, it isn't a proper backup in the sense that it isn't "off site" or stored in another location that is secured against a fire in the same room as the computer.
Oh, lets go buy a NAS box. Oh look, a bunch of drives in raid being used to back up your data.
Only difference is it isn't in the same case, positive benefits include not having to do a damn thing to maintain it. Lower risk of data loss, precisely zero effort involved in backing anything up, as every bit is backed up on more than one drive automatically. Looks like a backup solution to me. But I guess it makes more sense to just use the NAS and burn up a bunch of effort transferring everything over the network every Sunday at noon.
As far as home use goes, it most certainly is a backup solution. The only increased risk over not using a NAS would be if your power supply went to hell and nuked everything at once, or you dump your morning coffee on the pc. Otherwise, unless you are keeping everything off site, it is just as valid a backup solution as buying a nas and putting it in the closet.
If you have a problem with your PSU frequently burning up your hard drives, then you may have other, more pressing issues.
The only remaining argument is that any changes that are made happen across the board, and you don't have an older backup to fall back on. In terms of media, this is entirely irrelevant. When it comes to documents, and things which get changed and revised, a traditional backup solution of course is ideal. The correct way to back up work like that isn't even an option in home versions of windows is it?
I forget how it all works, but something involving shadow copy correct? Been a few years since I did my network admin thing in school, and wound up not working in the field anyways.Edited by Masta Squidge - 5/21/13 at 11:04am
