show snapshots


Description	Shows information about snapshots. The command will show information for all snapshots by default, or you can use parameters to filter the output.
Minimum role	monitor
Syntax	show snapshots [pattern `string`] [pool `pool`] [type standard\|replication\|all] [volume `volume`]
Parameters	pattern string Optional. Shows snapshots whose names contain the specified string. The string can include the following wildcards, singly or in combination. * Matches zero or more characters. ? Matches any one character. Use multiple '?' wildcards to find names of a specific length. For example, Vol?? will find names starting with Vol that are five characters long. [] Matches any character within the brackets, except a hyphen. Alphabetic characters are case sensitive. For example, [123] matches 1, 2, or 3. Use a hyphen between two characters to specify a range. For example, [0-9] matches any one digit. You can combine the list and range forms. For example, [xy1-3] matches x or y (but not X or Y), or 1, 2, or 3. pool `pool` Optional. Specifies the name or serial number of the pool that contains the snapshots for which to show information. A name that includes a space must be enclosed in double quotes. If this parameter is omitted, information is shown for snapshots in all pools. type standard\|replication\|all Optional. Shows only standard snapshots, only replication snapshots, or snapshots of all types. If this parameter is omitted, snapshots of all types are shown. volume `volume` Optional. Shows snapshots associated with the specified volume name or serial number. A name that includes a space must be enclosed in double quotes.

Retention Priority The retention priority for the snapshot. never-delete: Snapshots will never be deleted. high: Snapshots may be deleted after all eligible medium-priority snapshots have been deleted. medium: Snapshots may be deleted after all eligible low-priority snapshots have been deleted. low: Snapshots may be deleted. Snapshots that are mapped or are not leaves of a volume's snapshot tree are not eligible for automatic deletion.
