摘要:
In one aspect, a method includes storing a virtual machine disk in a first logical unit stored on a data store; replicating the first virtual machine disk used by a first virtual machine at a second virtual machine disk stored on a second logical unit on a cloud array storage device; storing changes to the first virtual machine disk on a journal stored on the data store; periodically rolling each virtual machine disk of virtual machines on the second logical unit to a same-point-in-time using the journal and taking a snapshot of the second logical unit at the same point-in-time and sending the snapshots to a cloud storage network.
