Maintaining archive devices
All archive disks need to be backed up just as you do working disks. Archive devices are usually spinning disks so are susceptible to failure over time if frequently used, and are even more likely to fail if they are not used for long periods of time.
Because archive devices are left inactive for long periods of time, they need to be spun up occasionally. I spin my archive devices at the end of every year as part of my housecleaning activities over the festive holiday period.
