Definitely. That's the whole point of even investing in a NAS in the first place isn't it. ?
Personally I don't scrimp on such stuffs because I have the technical know how to make machines work for me, and if I measure the cost of losing my data to an undetectable situation, I would have invested in a solution that give me a piece of mind. Enterprise or Consumer is totally beside the point, because the perspective of COST is different.
Also as another poster have suggested, switch on your documents versioning on your NAS if such a feature is available. HyperBackup also support backup versioning, so use it if you can.
However so, the ultimate decision is the owner of his/her data. If you value your data, you know what to do. If you think you are adequately protected, good for you.
That's all I have to share.
