Abstract
Some of the methods provided herein may include periodically revising a mirror of the target computing system, according to a predetermined backup schedule, the mirror being stored on the virtual failover volume resident on an appliance that is operatively associated with the target computing system, by periodically comparing the mirror to a configuration of the target computing system to determine changed data blocks relative to the mirror, storing the changed data blocks as one or more differential files in the virtual failover volume, and incorporating the changed data blocks into the mirror. In some embodiments, the systems and methods may be utilized to resparsify the virtual failover volume.
