No, Backup is separate and needs properly managed, not included in every "corporate" purchase.
I'm an IT infrastructure designer and implementer, so I'm not completely in the dark here.
What about smaller businesses? Tools prices starts at "free" (open source).
Free cheese exists only in mousetraps. Or TANSTAAFL, if you prefer it. However, we don't discuss such businesses. We're talking about writers and, possibly, other home non-business users. Of course, any business needs a much better backup system than a thumb drive regardless of its size, no arguing here.
