FalconStor had added continuous data protection (CDP) to its existing snapshot technology to produce FalconStor CDP. Regular snapshots are taken of files and any changes to files after a snapshot are recorded with a time stamp and stored in a journal file.

The software integrates with popular Windows applications and file systems: Exchange; SQL Server; Oracle; Sybase; NetWare; Notes/Domino and DB2. Complete applications can be rolled back to any point in time by using a scrollbar or 'visual slider'.

Don Mead, FalconStor's marketing VP, said: "The snapshots are automatically mountable and can be rolled back because of their transactional integrity."

"We've added intelligence. The window above the timeline scrolbar (visual slider) shows the amount of I/O hitting the disk at any time. If you see a spike of heavy I/O you can restore to the point just before it, and its risk of corruption just before a failure, and so avoid having to run a (time-consuming) database integrity check."

FalconStor CDP works with both direct-attached and networked storage. It is suitable for datacentres and for branch offices. A branch office can have local files backed up by CDP to a nearline storage array which can have its contents copied to a data centre for disaster recovery. Mead said: "We offer both branch office business continuance and disaster recovery."

The product can also be used by small and medium businesses in the form of a turnkey appliance.

Pricing information was not released. The products will be available from FalconStor's OEM, system house and reseller partners.

FalconStor added CDP to its virtual tape product a year ago. CDP is becoming a standard feature of disk-to-disk (D2D) backup and wide area file system products. It cannot be offered by tape-based backup products unless they have D2D technology added as a front end.
