Backing up to the cloud started mainly as an option for smaller companies, but enterprise backup vendors see it moving up into the enterprise.
CommVault and Symantec have made their backup software more cloud friendly for larger companies, and now enterprise virtual tape library (VTL) vendor Sepaton is preparing to help customers back up to private and public clouds.
Sepaton director of advanced technology Dennis Rolland said the vendor will have products that fulfill a cloud model. He’s not yet ready to talk about any specific cloud products, but he said Sepaton is putting together a cloud strategy built around two of its key capabilities.
“The main thing is that deduplication and low-bandwidth replication really make a cloud deployment possible,” Rolland said. “Our customers typically have short backup windows and a large amount of data to move. Deduplication reduces the cost of that storage footprint and replication sends only unique data after the first backup. Those are really the enablers. Cloud solutions today that don’t have dedupe, I don’t know how viable they will be in the enterprise to move large amounts of data.”
Rolland said organizations backing up to private clouds also need the ability to allocate performance and capacity according to business needs, and a multi-tenant model. He said many companies also want to use the public cloud to seamlessly create another tier of data protection.
Using the cloud for backup isn’t the only change Sepaton sees in enterprise data protection. Rolland said the rise of Ethernet in storage, the proliferation of virtual machines and emergence of OST for Symantec NetBackup customers is leading to more unified storage devices. This is changing Sepaton’s model because it started as a Fibre Channel-only VTL vendor before adding NAS and file-based interfaces.
“Ten-gigabit Ethernet is driving consolidation,” he said. “Ethernet is easier to manage that Fibre Channel. Users are asking for Ethernet support in every vendor’s roadmap. We can run Ethernet in same system simultaneously over FC. We can run a VTL emulation over Fibre Channel and OST to a disk device over Ethernet to the same system.”
