Riverbed Whitewater adds replication, data-pinning features

Latest Riverbed Whitewater cloud backup appliances ingest data faster and pin it to cache for immediate access.

Riverbed Technology Inc. today refreshed its Whitewater cloud backup appliances with three new models and a new operating system that includes pairwise replication to secondary appliances and data pinning to keep hot data in an on-site cache.

The new models -- the 3030, 2030 and 730 -- support 10 Gigabit Ethernet (GbE) for faster ingest rates to the cloud. The new features are part of the Whitewater Operating System (WWOS) 3.0 software.

Whitewater is designed as an alternative to tape backup for remote offices. The appliance is not intended to be a backup target, but uses the cloud as the target.

"If we have people asking, 'I just want to back up to the device,' that is not an option. You have to back up to the cloud," said Rich Faris, Riverbed's director of product management for Whitewater. "We are not forcing them to get rid of their backup server because it gives you the ability to catalogue. We are preserving the investment in the backup server. We just remove the cost of the tape expense."

The Whitewater 3030 includes 32 terabytes of cache in the 2U appliance, and scales to 96 TB with two expansion shelves. Riverbed claims the 3030 can ingest 2.5 TB per hour of deduplicated data and move 14.4 petabytes (PB) of data to the cloud, assuming a 30-1 deduplication rate.

The 3030 can hold three times as much capacity as the previously largest Whitewater appliance, the 3010. The 3010 had a 1.5 TB-per-hour ingest rate.

The 2030 gateway can handle 16 TB to 48 TB of cache capacity and move 7.2 PB of deduped data in the cloud. The device can ingest 2 TB of deduped data per hour.

To achieve these ingest rates, the 3030 and 2030 require 10 GbE connectivity.

The 730 holds up to 8 TB of cache capacity, supports 1.2 TB of data in the cloud and can ingest 1.5 TB per hour.

The pairwise replication -- also known as parallel replication -- lets customers replicate to another Whitewater appliance at a secondary location as well as the cloud. In the case of an outage, they can recover immediately at the secondary site. The data-pinning feature lets customers tier backup sets. They can make certain data available on the Whitewater cache for immediate access while less-critical data is stored in the cloud.

"They are adding parallel replication between the secondary site and the cloud so you have instantaneous recovery because it is cloud-based," said Ashish Nadkarni, IDC's research director for storage systems. It's almost like they put an intermediary between the primary site and the cloud."

Riverbed supports public cloud service providers including Amazon, Microsoft Windows Azure, Rackspace, Google, EMC Atmos, Savvis and AT&T Synaptic. With the new release, Riverbed added support for Symantec Enterprise Vault, as well as Amazon GovCloud for compliance data.
