Estimating the term…
A computer includes a storage segment fully allocated to an application. The storage segment initially includes a repeating initialization data pattern there within. After the application begins its workload, the application writes application data to a portion of the storage segment. A snapshot application takes a snapshot of the storage segment. After the snapshot, the application generates a post-snapshot-write to the storage segment. The snapshot application determines whether the post-snapshot-write modifies application data or modifies the repeating initialization data pattern. If the post-snapshot-write modifies the repeating initialization data pattern within the storage segment, the snapshot application blocks the repeating initialization data pattern from being copied and moved which resultantly blocks modification of the snapshot. If the post-snapshot-write modifies application data, the snapshot application copies and moves the application data to a destination storage location which resultantly modifies the snapshot to identify the destination storage location of the moved application data.
