EMC is entering the continuous data protection market.

The company will release a new product, RecoverPoint, this week, based on technology supplied by Mendocino. The software will continuously back up data, as well as instantly recover files and transaction-oriented data.

RecoverPoint runs on a Linux server and will save data on any EMC, HP, IBM or Hitachi array. It supports Sun Solaris, Windows 2003, and Oracle and SQL Server databases.

It differs from some other products on the market since it can be used to back up both file and database data to. Other products, including Symantec's Backup Exec andLiveState Recovery, or IBM's Tivoli Data Protection, only back up files created on a network.

EMC is not the first big-name company to look to Mendocino for CDP technology. HP this week announced it has agreed to resell Mendocino's RecoveryOne software.

EMC will expand support for RecoverPoint to Microsoft Exchange and IBM's DB2, as well as host operating systems AIX, HP-UX, Linux and Windows 2000 in the first half of 2006. It costs $75,000.
