FAST SNAPSHOTS |
| 摘要 |
A fast snapshot is configured to determine if a snapshot is utilized for asynchronous mirroring. The fast snapshot operation is performed by avoiding reference counts of the one or more data units associated with the snapshot from being updated at a creation time and a deletion time when the snapshot is utilized for asynchronous mirroring. |
