A RAID array isn't a backup. Your data is still live on it, an "rm -rf" away from destruction. HDDs fare poorly when shelved for a long time, RAID are even worse in that regard. OTOH a tape on a shelf is perfectly safe for 5 to 10 years or more (I recently restored 1998/99 sensitive data from LTO2 tapes written in 2003).

- wazoox 4y agoUnless you store your tapes right next to your cache of neodymium magnets, that should be pretty easy. Writing to a tape is very deliberate generally. Much more than writing to disks.
