You don’t need them … until you really need them.
This week, I nearly lost several days’ work. A corrupted computer file threatened multiple hours of effort.
I checked my primary backup. But without realizing it, I had copied to my external hard drive the version with a hidden, crippling error. The same with the high-capacity flash drive I always carry.
Fortunately I had a third backup: my spare laptop. On its screen I found the most recent, uncorrupted version of a six-page feature article.
Is keeping three separate backups, in three locations, excessive? Usually. But not when you really need them.
