The Cloud, Not Deduplication Alone, Will Lead To The Demise Of Tape
Friday, Iron Mountain and Microsoft announced a new partnership. Customers of Microsoft's backup offering, Data Protection Manager (DPM) 2007 service pack 1, can electronically vault redundant copies of their data to Iron Mountain's CloudRecovery service. This is welcomed news for DPM customers. Customers will continue to backup locally to disk for instant restore but rather than vault data to tape and physically transport tape to an offsite storage service provider, customers will vault data over the Internet to Iron Mountain. For disaster recovery purposes and long-term retention services, you need this redundant copy of your data offsite. By eliminating the physical tape transport you eliminate the risk of lost or stolen tapes or the need to deploy some kind of tape encryption solution. Microsoft DPM hasn't taken the backup world by storm since its introduction in 2005, but each subsequent release has added critical features and application support. Additionally, because it is often bundled in with Microsoft System Center, I expect adoption will increase among small and medium businesses (SMBs) and small and medium enterprises (SMEs).
There are dozens of online backup services and new ones emerge everyday. I took the time note the Microsoft and Iron Mountain announcement because I think it's one example of a many partnerships to come between a commercial backup application vendor and a cloud storage service provider. Other examples include partnerships such as Zmanda and Amazon S3. Symantec has built its own "cloud" with Symantec Protection Network (SPN) and existing Symnatec Backup Exec customers can vault their data to SPN. Whether it's partnerships between commercial backup vendors and cloud storage service providers or vendors that build their own cloud storage target, these partnerships will help you eliminate physical tape.
Deduplication in backup software and disk targets such as VTLs has helped customers reduce their reliance on tape and for companies that have less data and shorter retention periods, to eliminiat tape. But deduplication didn't bring about the demise of tape as quickly as many thought. First, while dedupe certainly reduces the capital acquisition cost of disk (because you need far less disk), it's not removable so you still need some way of getting the data offsite, and that means you have to buy two disk systems, locate them at different sites, buy a license for replication, and potentially increase your bandwidth between sites. Not to mention, that until MAID (massive array of idle disks) technology becomes mainstream, spinning disk consumes a lot more power than tapes sitting on a shelf.
But now combine cloud storage with deduplication, and a far greater number of SMBs and SMEs can eliminate tape. Cloud storage services such as Iron Mountain's CloudRecovery service gives customers their alternate site and remote disk target without the capital investment in a second site and system and deduplication greatly reduces the capital acquisition cost of the local disk but also the bandwidth required to transmit the data. And of course, with the data offsite, not on your premise, it reduces your power and cooling costs and the footprint for backup infrastructure.
I'm interested in your feedback. Do you have any secruity concerns with online backup and cloud storage services? What are your adoptions plans for these types of services? Are you seriously considering them today or is your organization not quite comfortable with the idea?
