KAZ launch data backup service

Telstra subsidiary Kaz has launched a remote backup and archival managed service for two Telstra-owned data centres in Sydney and Melbourne.

The hosted service, titled PC Backup, uses Kaz partner-designed software DeltaBlock and SendOnce to compress the data and back up only incremental data changes, not the entire file.

The service has been trialled over the last four months at 12 Australian organizations.

Peter Wilson, KAZ solutions and innovations marketing general manager, said the smarts of the service are held in the DeltaBlock application, adding the hosted service will be offered in the market as a pure backup service and is not limited to Telstra customers.

"The service backs data up to two, secured, mirrored data centres 1000 kilometres apart and is carrier-agnostic, so anyone with an IP connection can access it," Wilson said.

"But there is an inherent advantage for anyone already on the Telstra IP network as they will not have to use the Internet to access this so any up and down traffic between their PCs and the storage facility is 'free'.

"DeltaBlock is where the smarts come into it. For example, a 6.1Mbit PowerPoint slide with one text change would usually mean the entire file would have to be backed up; now DeltaBlock identifies the actual change, compresses the entire file to 21K and backs up the change, and files in 14 seconds using wireless."

The system uses 128-bit AES encryption, end to end. EMC has provided the storage area network, Telstra the network as well as the data centre and US-based Iron Mountain provided the DeltaBlock and SendOnce software.

Pricing is based on a 2GB storage plan for a PC or laptop at $27.50 a month, including GST. The 100GB server-based plan costs $456.50 a month including GST.
