Network Appliance is buying partner Topio for $160 million in cash.

The purchase will add the company's products to NetApp's storage management software.

Topio's software helps customers replicate, recover and protect data over any distance regardless of the underlying server or storage infrastructure. Based in Santa Clara, California, not far from NetApp's headquarters in nearby Sunnyvale, Topio also runs an R&D facility in Israel.

NetApp says the acquisition of Topio will help its customers replicate data on any vendor's system, including those of main rivals EMC, HP and Hitachi Data Systems, to any NetApp storage system.

NetApp expects to complete the acquisition before the end of the year. Topio will become a new business unit within NetApp and its facility in Israel will continue to operate after the deal closes, NetApp said.
