A method and system for source versus target metadata-based data integrity checking. Concerning backup operations directed to protecting given data, said given data may be subjected to corruption detection at the source prior to initiating a backup operation, however, said given data may not be checked for data integrity following transfer of said given data to a target storage medium prior to committing the said given data thereto. That is, at least presently, the prospect of data corruption compromising given data during the time window through which the given data journeys, usually via a network, from its source to a target storage medium, is often overlooked. The disclosed method and system, accordingly, propose a scheme directed to detecting corruption amongst data transferred from a source to a target storage medium, and handling said data given the determined integrity of said data.

Source versus target metadata-based data integrity checking

One example method includes moving a volume from a source server to a target server. In one example, the volume is moved and the need to copy the source data is eliminated. The volume to be moved is selected and metadata associated with the save sets stored on the volume is exported to a volume bootstrap, which is also stored on the selected volume. The volume is mounted or attached to the target server and the metadata is imported from the volume bootstrap. The volume is made read/write and is moved from the source server to the target server.
