Hard drive maker Seagate will buy EVault for $185 million in an acquisition designed to bolster Seagate's managed services business, the company said on Thursday.

EVault, in Emeryville, Calif., provides online network backup, recovery and data protection products for small-to-midsize businesses (SMB). Seagate said the market segment comprises 74 million businesses and represents a multibillion-dollar growth area.

EVault is a privately-held company founded in 1997 and has 250 employees and 8,500 customers in financial, heathcare and legal organizations.

The company specializes in on-site and in-lab data recovery for corrupted or inaccessible storage devices and often serves SMBs with limited infrastructure.

Seagate has sought over the last three years to expand its customer base from its core disc-drive business into managed services. Seagate Services focuses on backup, recovery and archiving for SMBs.

EVault is Seagate's third acquisition in the managed services field. Last year, Seagate bought Mirra, a maker of hardware and software that lets PC users back up their data and access it from any PC connected to the Internet.

Also in 2005, Seagate scooped up ActionFront Data Recovery Labs, an in-lab data recovery company.

Seagate said it expects the EVault deal to close by April, its third fiscal quarter for 2007.
