NEW! Top 10 Storage Startups to Watch: Page 21 of 24

Teneros competes most closely with block-based replication from Double-Take Software, Neverfail, and XOsoft (now part of CA), as well as with hosted disaster-recovery services. But at least one analyst thinks it has a clear differentiator.

"To me, there is a big difference between data recovery and application recovery," says Arun Taneja of the Taneja Group. He says Teneros, along with a handful of other vendors, including Sonasoft and Cemaphore, maintain "transactional integrity" in applications instead of just replicating block-level chunks of data.

So far, Teneros has managed well, even though it is not yet profitable. The company, founded in 2003, claims to have about 300 customers and 92 employees. And in January, the startup scored $40 million in VC funding, bringing its total to $84.5 million.

That's a big chunk of change. And if progress keeps up at Teneros, it may prove to be a solid investment.
