BakBone NetVault TrueCDP

 
Continuous data protection (CDP) is a backup methodology that continuously tracks and records data modifications independently of the primary data, enabling recovery from any point within a configurable window of time. Since the software is continuously running, every time a file changes CDP logs that change. This allows a CDP-protected system to roll back any changes to the system at any time.

CDP is best suited for those with high-value, time-sensitive data sets. Typically, such data is coupled with very ambitious recovery point objectives and recovery time objectives (RPOs and RTOs).

Real-time replication is similar to CDP in that data changes on the source server(s) are captured and journaled as they occur. These changes are then replicated to (or mirrored to) the destination server.

One potential drawback with a pure replication solution occurs when data on the source server becomes corrupted. If this data exists in the replication data set, the corrupted data is propagated to the destination server, overwriting earlier, uncorrupted data. A critical advantage offered by CDP technology is the ability to recover to a point just prior to the moment when data corruption occurred.

BakBone's NetVault: TrueCDP allows you to continuously capture byte-level file system changes in real time. NetVault: TrueCDP offers a choice of any-point-in-time (APIT), as well as fixed-point-in-time (FPIT), snapshot data recovery for Linux environments.
