SYSTEMS AND METHODS FOR COPYING DATA MAINTAINED IN A DYNAMIC STORAGE VOLUME AND VERIFYING THE COPIED DATA

摘要

A first volume comprising a plurality of blocks stored in a first location is accessed. A plurality of hash values representing the plurality of blocks is stored. The plurality of blocks is copied to a second volume stored in a second location, generating a copied volume. The copied volume is verified based on the plurality of hash values. In one embodiment, the first volume is altered, after the plurality of hash values is stored. Altering the first volume may include changing data in a selected one of the plurality of blocks. The first volume may be altered during copying of the plurality of blocks to the second volume.
