Abstract
A computer implemented method for replicating virtual machine disk volumes on a storage array supporting reading signatures of data based on offset of data by reading signatures of data of a production virtual machine on production site; wherein reading the signature includes mapping a virtual machine disk offset into a physical storage offset and reading the signature from the physical storage; reading signatures of data of a replica virtual machine used to replicate the production virtual machine on a replica site wherein reading the signature includes mapping a virtual machine disk offset into a physical storage offset and reading the signature from the physical storage; and based on determination the signatures are not identical marking the locations for synchronization in a synchronization structure.
