Abstract
In one aspect, a method includes providing data protection to data in a first volume at a first data protection appliance by storing a copy of the data in a second volume using a second data protection appliance, tracking changes between data locations in the first volume and the second volume using a delta marking stream (DMS) and receiving, at the first data protection appliance, metadata. The metadata is intended to be committed to the DMS. The method further includes mirroring the metadata at a third data protection appliance.
