Williams Data Management, which helps small- and medium-sized businesses protect their data assets, has acquired Pasadena information storage firm Files On Call.

Terms of the buy were not disclosed.

Williams Data Management said the acquisition will extend its reach into the San Gabriel Valley. The Vernon information management service provider will also take on Files On Call’s current clients through the deal.

“Of the more than 50 clients we added in the first six months of 2014, 85 percent moved from a national data storage company,” said Chief Executive Douglas Williams in a statement. “We know local businesses better than any national brand and we build relationships that grow, not erode.”
