Computer Associates has bought XOsoft, a company that sells data replication and recovery software, for an undisclosed sum.

The purchase will improve CA's storage management product line by integrating its technologies into its own BrightStor backup products.

XOsoft's products are designed to provide uninterrupted access to file and application servers, including Windows servers, Microsoft Exchange, Microsoft SQL and Oracle, and allow recovery after disasters.

The purchase follows CA's acquisition last month of MDY Group International, a provider of records management software and services. XOsoft serves more than 1,600 customers in 42 countries and is located in Massachusetts.

The acquisition will help CA offer customers a multi-layered approach to IT system backup and recovery, including traditional backup, offsite vaulting and disaster recovery, the company said. CA will market and support XOsoft's products through its direct sales group and authorised XOsoft and CA partners, the company said.

CA's BrightStor ARCserve Backup provides customers with a variety of storage options, including encryption, integrated anti-virus protection, media management and snapshot backup and recovery capabilities.

XOsoft complements these capabilities by adding continuous protection and quick recovery, significantly reducing backup workloads, CA said.
