Question
Although RAID may be utilised to enable live backups of physical hard drives, it is possible that doing so will restrict the amount of space that can be used by the backed-up discs. Do you believe that it is necessary to sacrifice half of your disc space in order to ensure that you always have a backup? Which configuration of RAID should be used to safeguard the hard discs of a home computer that has frequent interruptions in its power supply?
