The Data Protection Process

After completing an initial replica, all point-in-time volume snapshots are

scheduled on the CDP 3.0 Enterprise Server. The CDP 3.0 Enterprise Server then connects

to the CDP 3.0 Enterprise Agent program according to the user-determined schedule

and synchronizes changed disk sectors to the CDP 3.0 Enterprise Server. The CDP 3.0

Server creates a new point-in-time image of the disk volume every time it connects to

the agent for synchronization. The point-in-time images are called recovery points and

stored in what R1Soft calls a Disk Safe.

Recovery points consist only of a copy of changed disk sectors.

This means it usually takes only minutes, or even seconds, to complete disk

synchronization, even on very large volumes. The more frequently recovery points

are scheduled, the quicker they complete. When compression is enabled, hundreds

of recovery points can be stored in less space than it takes to store one disk image.

In between synchronization requests from the CDP 3.0 Server, the CDP 3.0 Enter-

prise Agent passively tracks changes to the hard disks as they happen. This process

introduces minimum overhead and requires a relatively small amount of memory.
