Powered Replication Makes the Difference

Data replication (DR) requires compute power at each endpoint for greatest efficiency. This is especially true with Cloud Computing as we move files back and forth between terrestrial systems and the grid. Web 2.0 push technologies are ok for a few files but bog down quickly under load.

There are four (4) primary reasons you need powered replication; compression, encryption, delta change calculations, and snapshot (versioning) rotation.

The basic cycle of compress at source, transmit, de-compress at target is critical for reducing bandwidth. Similarly the encrypt, transmit, un-encrypt cycle ensures in-flight security for sensitive data and maximum utility at both ends. Both require compute power at the endpoints.

Delta change calculations are the best way to shorten the backup window at the source by sending the least possible amount of data which is then combined with the unchanged portion of prior versions of those files at the target. Delta change, or commonality factoring, is the key to efficiently keeping pace with changing data.

Finally, the preservation of point in time snapshots definitely requires compute power at the target endpoint. Before combining the previous version of files with the latest changes, a powered replication solution will rotate the snapshots and create synthetic full restores.

Ideally the horsepower to perform all of these tasks should not be stolen from the systems being protected but provided by a one-to-many solution that introduces minimal load.

These four (4) methods, compression, encryption, delta change replication, and snapshot rotation for full synthetic restore of terrestrial, virtual, and cloud computers are all seamlessly delivered by WarLock Software DR+ solution.
