Security should be paramount concern with cloud-based e-mail recovery

June 30, 2009, 08:13 PM —  Network World — 

Cloud-based disaster recovery has become a viable option for safeguarding e-mail, but IT shops need to ask tough questions about data security and resiliency before committing to a vendor, analysts say.

IT shops should stick with service providers that have multiple Tier 4 data centers, and can promise replication between sites for redundancy, Forrester analysts Stephanie Balaouras and Christopher Voce write in a June report titled "Protecting Email with the Cloud." 

"If you do an Internet search for 'online backup,' you will find dozens of providers," Forrester says. "But not all providers have 'telco-class' data centers, and some don't even bother to have alternative sites of their own."

Forrester says its clients typically say security is the biggest roadblock to adoption of software-as-a-service. "Beyond ensuring that your data will be encrypted in flight and at rest, you should also ask your service provider if it has a SAS 70 Type II certification as well as certifications for ISO standards … that spell out specific auditing requirements for hosting and security customer information," Forrester advises.

That being said, there are several advantages to using cloud-based e-mail continuity and recovery services, particularly for companies that lack a second data center, the financial resources to make new up-front and ongoing investments, or the expertise to implement and manage a new disaster-recovery rollout.

E-mail recovery services are being offered by several types of companies, such as hosted mailbox providers; e-mail supporting service vendors such as Dell MessageOne, Global Relay and Symantec/Message Labs; disaster-recovery service vendors such as IBM and SunGard; and online backup vendors such as AmeriVault, i365 and Iron Mountain.

"Traditional methods [of ensuring e-mail recovery and continuity] carry heavy facility, hardware, software and personnel requirements, and the capital and operating expenditures can be significant," Forrester writes. "Cloud-based message continuity offerings are a compelling alternative because they offload cost and responsibility to a provider."

Where Google Chrome security fails: the password
I heard mention that the Chrome OS will have some sort of encryption available a la bitlocker. If it's possible to encrypt personal data using another password or key, then it may have potential for very secure data.... And Ubuntu has an 'encrypt home directory' option, perhaps google should follow suit.
