SimpleDB作为备份？

Question

Is there any solution (RDBMS or NoSQL) that can use SimpleDB as a backup?

Thanks, A.

Answer 1

I'm pretty sure no RDBMS can be configured to do this, and I doubt they ever will. First, SimpleDb is a quasi-competitor to commercial databases so it wouldn't make sense for most companies to build this. Second, it would have a huge negative effect on transaction performance since writing transactions to SimpleDB would probably take at least 100 times as long as writing them to disk.
