That is why you need frequent backups. RAIDs with parity are to ensure continuous operation without loss of data if a drive in the RAID should fail while in use. For most home users, a shutdown due to a disk failure would just be an inconvenience as long as the data is properly backed up. RAID will not protect your data if your HDDs all fail due to a virus, PSU failure, fire, theft, user error (we all have our Murphy moments), etc. For that kind of protection, redundant backups kept both onsite (but not connected to the computer) and offsite are essential. Backing up a RAID requires the backup be on a single volume which requires a RAID box of some sort. It is much simpler and less expensive to backup individual HDDs than RAIDed ones.
