Abstract: Virtual computing instance data that are stored across multiple storage volumes are replicated in a manner such that the write order is maintained. The frequency of the replication is set so that the recovery point objective defined for the VM data can be satisfied. The replication includes the steps of determining a set of logical storage volumes across which the virtual computing instance issues dependent write IOs, issuing a first command to the virtual computing instance to block new IOs and to block receipt of IO acknowledgements, issuing a command to create replicas of all the logical storage volumes in the set, and then issuing a second command to the virtual computing instance to unblock new IOs and unblock receipt of IO acknowledgements.

The replication includes the steps of determining a set of logical storage volumes across which the virtual computing instance issues dependent write IOs, issuing a first command to the virtual computing instance to block new IOs and to block receipt of TO acknowledgements, issuing a command to create replicas of all the logical storage volumes in the set, and then issuing a second command to the virtual computing instance to unblock new IOs and unblock receipt of TO acknowledgements.
