Abstract
Systems and methods are disclosed for checking the data integrity of a data object copied between storage pools by comparing data fingerprints of data objects, comprising 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 that creates a fingerprint from a subset of the data object; sending the partial fingerprint of the data object to the target data store; sending any new data contents to the target data store; and creating a partial fingerprint of the data object at the target data store and comparing it to the received partial fingerprint to determine if they differ, thereby allowing incremental verification that the copy of the data object at the target data store is the same as at the source data store.
