Start-up Kashya has upgraded its data replication appliance by adding continuous data protection software, letting customers combine the off-site protection of data with local back-up capability.
The KBX5000 CDP appliance, which sits in the network between the SAN and the WAN router, uses rules the IT administrator sets to govern the replication of data or the backup to local storage. The company said that it allows customers to save money by replacing SAN-based software and hardware, such as EMC's TimeFinder replication software, McData's UltraNet Edge Storage Router and EMC's NetBackup software, with an integrated software-based appliance.
The KBX5000 CDP allows data recovery locally or remotely at any time. For instance, for normal recovery of data, IT administrators may use the local image, while in the event of local data failure, they might retrieve that data remotely.
Arun Taneja, senior analyst for the Taneja Group, says that adding this capability to the KBX5000 makes sense. "Since you are collecting the information to put out over the WAN, why not take it and create a back-up product out of it," Taneja says. "I'd expect CDP vendors to get into the data replication business, too."
Acopia, a network-attached storage virtualisation vendor that recently introduced its next-generation product, says it also will add CDP capability to its product.
Data replicated over distance with the KBX5000 is compressed on a 25-to-1 ratio and rules determine whether data will be saved synchronously, asynchronously or in snapshot format, thus allowing for bandwidth optimisation.
Policies can be set not only on whether data will be remotely or locally saved, but for how long it will be retained and the type of media to which it will be saved.
The company's KBX5000 CDP is in beta tests and is expected to be available in mid-August. The cost starts at $25,000. The CDP module is installed on the KBX5000, which starts at $50,000.
