Some of the tenants about backup is that we need to have one to backup to. Another with the copy in a write protected state and the last copy not in the same building or city.
That means we need 3 drives. And they need a write protect switch to keep the contents safe.

I am looking at purchasing an external drive for backup purposes. What is a recommended size for a backup drive. My hard drive is 55G and with about 29 used.
