It would seem that a traditional backup solution as we know it is changing its meaning.

A regularly scheduled backup is a great thing to offer. However, there are more and more companies that go toward RAID solutions, data mirrowing and cloud computing - which makes your website data dynamic. So it makes me wonder whether a company that offers shared web hosting on cloud architecture should worry about daily backups since its so hard to lose data, if it is shared between X number of servers...

Or am I missing the point?
