Continuous Protection 115

Continuous Protection Overview

You can protect datacenter workloads by addressing disaster recovery (DR) through

virtualization. Taking a P2V approach, vConverter preserves a virtual backup copy of a

physical machine. When you select Continuous Protection as the conversion type,

incremental replication is used. During this process, network usage is minimized

because only changes to source data files are transferred to the target. You define the

intervals at which these transfers occur.

Unlike Synchronized Cutover, Continuous Protection VMs are bootable between

conversion passes. If your production source becomes disabled or corrupted, you can

revert to the VM target and boot to an image consistent with the state of the source

system at the last synchronization. If the target VM is powered on between

synchronizations - any changes made to the VM will be lost on the next

synchronization. The exception to this is newly added files which are missing on the

source - these files will remain in the target image.

Note Synchronizations in Continuous Protection Mode requires VSS - this mode is unavailable

for converting Windows 2000 systems. Continuous Protection is only available for Windows

conversions.

The diagram below explains in more detail what happens in Continuous Protection

Mode.
