Abstract
Techniques for improving snapshot performance are disclosed. In one embodiment, the techniques may be realized as a method for improving snapshot performance comprising initiating change block tracking for each unit of storage associated with each of a plurality of virtual machines, creating backup images of each unit of storage associated with each of the plurality of virtual machines, quiescing each of the plurality of virtual machines, and creating snapshots of each unit of storage associated with each of the plurality of virtual machines. The techniques may include identifying one or more changed blocks in at least one of the backup images using the change block tracking, editing the at least one of the backup images by replacing the identified one or more changed blocks using corresponding blocks from at least one snapshot of the snapshots, and releasing the at least one snapshot based upon a determination that editing has completed.
