Abstract
A method for snapshot reversion, the method may include initializing a recovery of a storage system, from a failure that stopped a replication of a failed replication snapshot to an other storage system; wherein the other storage system reverted to an older snapshot not stored in the storage system; and reverting to the older snapshot, by the storage system using older snapshot metadata and data received from the storage system; wherein the older snapshot data may include a non-existing indication for a snapshot segment that existed in a snapshot that followed the older snapshot and not exists at the older snapshot, and wherein the data may include one or more older snapshot segments; wherein the reverting to the older snapshot is executed without undoing changes that were made since the older snapshot.
