Abstract
Technologies are described herein for providing assisted asynchronous replication between a first storage server having a first current state and a second storage server having a second current state. An instruction to roll back a first storage server from the first current state to a previous state according to a previous snapshot is received. The first storage server is then rolled back from the first current state to the previous state according to the previous snapshot. A determination is made as to whether the previous snapshot is available on a second storage server. Assistance data is then retrieved. A last consistency point common to the first storage server and the second storage server based on the assistance data is identified, where the last consistency point is at or prior to the previous snapshot. The second storage server is rolled back from the second current state to the last consistency point.
