Abstract
Architecture for restoring nodes. After restoring a node, fix-up occurs to make the node appears as a different node than before the restore operation. The node appears as a new node, which new node knows the data up to a certain point from when the new node had the prior identity. This allows for new changes generated by the new node to flow to the other nodes in the topology, as well as have the changes that the prior identity sent to other nodes flow back to the new node. In other words, the architecture maintains information to create the new node in the topology while maintaining prior data knowledge. Additionally, item level metadata of associated data items is updated to correlate with the updated data items so that changes can be correctly enumerated and applied. This metadata update occurs across scopes of which the data items are included.
