“If you're basing your existing disaster recovery plans around tapes that you're shipping back and forth between your local sites and one or more offsite storage facilities, then you already know that using tapes for recovery leads to days' worth of data loss, recovery times that can take from days to weeks, and recovery reliability issues that (for whatever reason) mean you can't always get back the data you need.”

Interesting product.  I wonder if it works.  I’ll do some more investigation..
