If you're new the the continuous data protection (CDP) game, continuous is the KEY word here. Most of us are familiar with CDP on Windows machines where changes are made and copies are automatically performed-capturing every change of data over time. The benefit here, as opposed to backups taken at a particular time, being you can restore to any point in time. Quite handy.

While CDP technology is not new to the Windows market, R1Soft currently offers the only CDP product that works cross-platform, for Linux and Windows. Since most IT environments are mixed-platforms, the need for a solution capable of supporting both platforms is strong and growing.

For your enjoyment, a current press release for the version just released: R1Soft Releases Windows 2.0 Continuous Data Protection Software
