I have a RAID 1 configuration (or will have when I set it up) but I am still concerned about losing important data. So just how safe is RAID1 as a backup strategy? I know it's not a true backup solution since deleting a file off one will be mirrored in the other, but that's not a likely scenario (I only add to my important repositories, never delete from them).
The thing that worries me is that both HDDs will be in the same box in close proximity and therefore prone to the same type of failure at the same time, such as overheating or being subject to a power surge. How likely is this in reality? Am I worrying about nothing? Would you always recommend an offsite backup for critical data as well?
