Abstract:
Systems and methods for replicating a snapshot of a volume are described. In one embodiment, a storage controller of a storage system may be operable to initialize a first replication process between a first storage volume of the first storage system and a second storage volume of a second storage system, copy content from a first system snapshot of the first storage volume to a second system snapshot of the first storage volume, and copy content from a first user snapshot of the first storage volume to the first system snapshot of the first storage volume. In some cases, a system snapshot is not accessible to a user and a user snapshot is accessible to the user. In some cases, at least one of the system snapshot and the user snapshot include a point in time capture of data on the first storage volume.
