You can’t have a conversation about IT transformation or data protection modernization that doesn’t include “the cloud” somewhere in it. And today, there are a wide range of cloud services that offer data protection capabilities:
- Backing up SaaS offerings like Office365, Google Apps for Work, or Salesforce – see my earlier blog about SaaS backup.
- Backup-as-a-service (BaaS).
- Disaster Recovery-as-a-service (DRaaS).
- Augmenting an on-premises backup solution with a tertiary Storage-as-a-service (STaaS) tier.
I covered BaaS, DRaaS, and tertiary cloud in late 2013 in an ESG research report and am in the process of updating some of those research points, but it is interesting to see how diverse the offerings are in even just the STaaS market:
- Cloud-gateway solutions such as NetApp SteelStore or EMC’s Maginatics.
- Every backup software vendor's flocking to a variety of public-cloud storage providers as a tier.
- Every backup hardware vendor's effort to somehow get its appliances in an IaaS scenario or hosted by MSPs, so that its appliances can replicate to a cloud solution.
Last week, Google may have changed everyone’s math.
“Math,” meaning not just the dollars and cents, but the expectations of how cloud storage can be consumed as part of a data protection architecture. Before now, almost every cloud-extended storage offering that was leveraged for data protection utilized the same grade of public-cloud storage that was suitable for either protection or production usage. As such, while you could certainly trade the CapEx requirements of owning and running your own secondary storage at your own secondary site with the OpEx model of storing data in the cloud, you could certainly find economic scenarios where well-managed, self-owned storage beats cloud-based storage and vice versa as well. There wasn’t always an absolute economic winner because your data was on disk – yours, theirs, or otherwise.
Google Cloud Storage Nearline is designed specifically for providing low-cost storage for archiving, backup, and BC/DR. From a solution perspective, this lines up with several key industry trends:
With Nearline’s performance for retrieval being measured in single-digit seconds (with predictable SLAs) and an economic model that looks closer to tape economics than typical cloud-storage (disk) economics, it should not be a surprise to see early support from names like Symantec (with NetBackup 7.7 support), NetApp (SteelStore), Geminare (DRaaS), etc. Perhaps the only surprises are 1) Why didn’t Google do it sooner? and 2) Why hasn’t anyone else cracked the code to offer “warm” cold storage?
That being said, while most data protection technology modernization conversations have already included cloud considerations, those IT professionals’ managers who are balancing solution benefits/tradeoffs with economics in data protection may now be more interested.
