Abstract:
In traditional storage arrays, the number of clones permitted inside the storage array may be limited by the amount of available storage. Further, clones stored on the array may require significant storage resources. Thus, the number of clone stored by the storage array may also be limited by the storage system memory and not just by the disk space. Accordingly, example embodiments of the present invention allow for creating and maintaining a plurality (e.g., an unlimited number) of thin asynchronous clones in storage, even if replica storage is capable of storing only a limited number of snapshots. Further, example embodiments of the present invention allow clones to be freely attached and detached from the replication environment for various purposes.
