Abstract
Techniques for optimizing a remote data copy using multiple storage nodes. The techniques include receiving a copy command for a volume at a first node, a first subset of VOL slices being owned by the first node, and a second subset of VOL slices being owned by a second node. The techniques include obtaining, by the first node, respective diff bitmaps for the first subset of slices and the second subset of slices. The techniques include sending the diff bitmap for the second subset of slices to the second node. The techniques include performing, by the first node, a first copy operation based on the diff bitmap for the first subset of slices, and performing, by the second node, a second copy operation based on the diff bitmap for the second subset of slices, the second copy operation being performed at least partially in parallel with the first copy operation.
