Drive failures are really rare until they happen when your data is personal experience of a few devices. When you worry about a data centre or n and or rather a lot of other systems with storage then you realise that it happens with monotonous regularity. Now keeping a few short copies is also fine provided you don't make mistakes. Have you ever wanted to recover from a cock up you did six months ago or three years ago? You do offsite (Tarsnap), so you have covered off local failures - cool. Everyone's needs are different and the value they place on their data is different but I would respectfully suggest that you think really hard about how important some bits of your data are and protect them appropriately. Fuck ups are hard to recover from 8)
