Abstract
A technique for providing access to a data object serving as a target of snapshot-shipping replication includes taking a system snap of the data object after completion of each of multiple snapshot-shipping updates. In response to receiving a request to take a user snap of the data object, a data storage system redirects the request to a previously generated system snap, so that the data storage system takes the user snap of the system snap rather than taking the user snap of the data object itself.
