By now, you've probably heard that Microsoft's (NASDAQ:MSFT) aptly named Danger subsidiary didn't properly back-up server-stored data for users of T-Mobile Sidekick phones. The outage raises questions about the reliability of cloud-computing environments, as did earlier outages of Google's (NASDAQ:GOOG) Gmail service.

Can we get past this? Outages happen. They will continue to happen. As reliable as it is, the Internet is neither efficient nor 100% reliable. If it were, Web content delivery services wouldn't exist.

As investors, we need to recognize this outage as profit opportunity. The Danger data drain was more than a miscue; it illustrates a vulnerability in the cloud computing value chain, a hole that can only be filled with new and better data management and backup tools.

Backup?
Right, backup. If we're honest with ourselves, we'll admit that we like cloud computing. We like that it's cheap, and we like that we don't have to manage much of what's under the hood. This is why salesforce.com (NYSE:CRM) continues to be a massive-growth winner.

Therein lies the opportunity. See, if we aren't about to abandon cloud computing, running from the data center like a screaming teenager fleeing some horror-movie killer, then we're left with only one choice: Fix what remains by making cloud computing more reliable. Data management and backup software can copy, replicate, and store information where it can never be lost.

Have you checked the vault?
The technology is in demand. Ask EMC (NYSE:EMC) and NetApp (NASDAQ:NTAP), which got into a bidding war over backup specialist Data Domain over the summer. EMC prevailed after agreeing to pay $2.1 billion for the company.

Thanks to acquisition, attrition, and the Darwinian cycle of innovation that defines the tech industry, few public data-management pure plays remain. VMware (NYSE:VMW) is close, but its virtualization technology offers efficiency more than protection -- though data protection and preservation is part of its pitch.

If not VMware, whom? CommVault (NASDAQ:CVLT) could be the best remaining opportunity, even if our 140,000-strong Motley Fool CAPS community has mixed feelings about the stock:

They're right to be skeptical. CommVault has just about tripled from its 52-week low, and consequently may be priced for unsustainable growth. There's just one problem: Evidence points to accelerating growth in cloud computing, and Danger's miscue could create commensurate demand for data management and backup technology.

But that's also just my take. What would you do? Would you buy CommVault at today's prices? Let us know by signing up for CAPS today. It's 100% free to participate.
