Abstract

Official abstract text for this publication.

Techniques for initializing a replication relationship between virtual machines are described herein. The techniques include performing one or more pre-requisite checks, determining, at least partly in response to performing the one or more pre-requisite checks, one or more first data blocks associated with a first virtual machine that differ from one or more second data blocks associated with a second virtual machine. The second virtual machine may be instructed to send the one or more second data blocks that differ from the one or more first data blocks to the first virtual machine.

First claim

Opening claim text (preview).

What is claimed is: 1. A method comprising: under control of one or more processors: receiving a backup of a primary virtual machine at a recovery virtual machine, the backup comprising a copy of data stored in memory associated with the primary virtual machine; storing the backup to a first memory associated with the recovery virtual machine, the backup being stored as one or more recovery data blocks; calculating a first data signature for at least a portion of a data bloc…
