*General* rule of thumb: greater use = greater risk of wear = greater
risk of failure. But any BU is generally better than no BU at all.

If your sole backup (emphasis on 'sole', hence my A/B comment) is a HD
being run 24/7, I'd personally consider that risky. Most advocate an A/B
approach, with off-site rotation - regardless of storage media.

Risk assessment would include how valuable the data in question is.
