Abstract: System and method for creating group snapshots of multiple storage objects uses storage structures to store the storage objects in a storage system. In order to create a group snapshot of storage objects, a prepare snapshot process is executed at each of multiple host computers managing the storage objects as storage structures to block input and output operations on the storage objects stored in the storage structures. A commit snapshot process is then executed at each of the multiple host computers to create snapshots of the storage object in the respective storage structures. In addition, the snapshots of the storage object are recorded in the respective storage structures as snapshot entries in the respective storage structures.

Abstract: System and method for creating linked clones of storage objects stored in a storage uses a target storage structure that includes a linked clone being created from a selected snapshot of a storage object and surface snapshots. The linked clone is created in the target storage structure with references to the selected snapshot of the storage object in a source storage structure without completely copying the selected snapshot to the target storage structure. The surface snapshots, which correspond to other snapshots of the storage object in the source storage structure, are created in the target storage structure with references to the other snapshots without completely copying the other snapshots to the target storage structure to produce the linked clone with similar snapshots as the storage object at a point in time when the selected snapshot was captured.

Abstract: System and method for managing space in storage object structures stored in a storage system uses an object B tree structure to manage a storage object in a storage object structure in the storage system, which provides virtual physical block addresses for data of the storage object and for metadata of nodes of the object B tree structure. The metadata of the nodes of the object B tree structure is written in the storage object structure using first real physical block addresses, which are translated from the virtual block addresses for the metadata of the nodes of the object B tree structure using a metadata system file B tree structure. The data of the storage object is written in the storage object structure using second real physical block addresses, which are translated from the virtual block addresses for the data of the storage object using a data system file B tree structure.
