Abstract
Systems and methods are disclosed for checking the data integrity of a data object copied between storage pools in a storage system by comparing data fingerprints of data objects, by scheduling a series of successive copy operations over time for copying a data object from a source data store to a target data store; generating a partial fingerprint of the data object at the source data store using a data fingerprinting operation that creates a fingerprint from a subset of data of the data object; sending the partial fingerprint of the data object to the target data store; sending any new data contents for the data object to the target data store; and creating a partial fingerprint of the data object at the target data store and comparing it to the partial fingerprint sent to the target data store to determine if they differ.
