Under the "snapshots" tab is the list of active snapshots of the share. This list is divided
into two tabs: the "
Snapshots" tab is used for browsing and managing snapshots. The "Schedules" tab manages
automatic snapshot schedules. Within the "
Snapshots" tab, you can select between viewing all snapshots, only manual snapshots, or
only scheduled snapshots. For each snapshot, the following fields are shown:
The name of the snapshot. There are two types of snapshots: manual and automatic.
Manual Snapshots: "Name" is the name provided when the snapshot was created. Manual snapshots
can be renamed by clicking on the name and entering a new value.
Automatic Snapshots: There are three types, and they cannot be renamed:
- .auto: User-configured scheduled snapshots with custom retention policies (see Scheduled Snapshots).
- .ndmp: Used for NDMP backup and automatically pruned.
- .rr: Used for remote replication and automatically pruned.
The date and time when the snapshot was created.
The amount of unique space used by the snapshot. Snapshots begin initially referencing all the
same blocks as the filesystem or LUN itself. As the active filesystem diverges, blocks that have
been changed in the active share may remain held by one or more snapshots. When a block is part of
multiple snapshots, it will be accounted in the share snapshot usage, but will not appear in the
unique space of any particular snapshot. The unique space is blocks that are only held by a
particular snapshot, and represents the amount of space that would be freed if the snapshot were to
The total amount of space referenced by the snapshot. This represents the size of the
filesystem at the time the snapshot was taken, and any snapshot can theoretically take up an amount
of space equal to the total size as data blocks are rewritten.
Show the number of clones of
the snapshot. When the mouse is over a snapshot row with a non-zero number of clones, a "Show..."
link will appear. Clicking this link will bring up a dialog box that displays the complete list of
