show replication-snapshot-history


Description	Shows information about the snapshot history for all replication sets or a specific replication set. You can run this command on either the primary or secondary system to see snapshot-history settings for a replication set and details about local replication snapshots. In console mode, this command does not show the serial numbers of items such as replication volumes. To see serial numbers, run this command in API mode.
Minimum role	monitor
Syntax	show replication-snapshot-history [`replication-set-ID`]
Parameters	replication-set-ID Optional. The name or serial number of a replication set for which to display information. A name that includes a space must be enclosed in double quotes. If this parameter is omitted, information is shown for all replication sets.
Output	Snapshot settings: Replication Set The replication set name. Snapshot History disabled or off: A snapshot history will not be kept. secondary: A snapshot history set will be kept on the secondary system for the secondary volume, using snapshot-count and snapshot-basename settings. both: A snapshot history will be kept for the primary volume on the primary system and for the secondary volume on the secondary system. Both snapshot histories will use the same snapshot-count and snapshot-basename settings. Count The number of snapshots to retain in snapshot history. When a new snapshot exceeds this limit, the oldest snapshot in the snapshot history is deleted. Basename The user-defined prefix for the snapshots. Retention Priority The retention priority for snapshots, which is used when automatic deletion of snapshots is enabled by using the set snapshot-space command. In a snapshot tree, only leaf snapshots can be deleted automatically. Deletion based on retention priority is unrelated to deleting the oldest snapshots to maintain a snapshot count. never-delete: Snapshots will never be deleted automatically to make space. The oldest snapshot in snapshot history will be deleted once the snapshot-count has been exceeded. high: Snapshots can be deleted after all eligible medium-priority snapshots have been deleted. medium: Snapshots can be deleted after all eligible low-priority snapshots have been deleted. low: Snapshots can be deleted. Snapshot information: Local Snapshot The snapshot name. Creation Date/Time The date and time when the snapshot was prepared or committed. Snap Data The total amount of write data associated with the snapshot. Unique Data The amount of write data that is unique to the snapshot
