Project Snapshots

Snapshots are read only copies of a filesystem at a given point of time. For more information on snapshots and how they work, see the concepts page. Projects snapshots consist of snapshots of every filesystem and LUN in the project, all with identical names. Shares can delete the snapshots individually, and creating a snapshot with the same name as a project snapshot, while supported, can result in undefined behavior as the snapshot will be considered part of the project snapshot with the same name.

Project Snapshot Properites

.zfs/snapshot visible

Filesystem snapshots can be accessed over data protocols at .zfs/snapshot in the root of the filesystem. This directory contains a list of all snapshots on the filesystem, and they can be accessed just like normal filesystem data (in read only mode). By default, the '.zfs' directory is not visible when listing directory contents, but can be accessed by explicitly looking it up. This prevents backup software from inadvertently backing up snapshots in addition to new data.

Table 12-25  Project Snapshot Values
BUI Value
CLI Value
Description
Hidden
hidden
The .zfs directory is not visible when listing directory contents in the root of the filesystem. This is default.
Visible
visible
This .zfs directory appears like any other directory in the filesystem.
Scheduled Snapshot Label

This optional property appends a user-defined label to each scheduled snapshot and is blank by default. The label can either be set for an individual share, or set for a project and inherited by its shares, but not both. Snapshot labels can help identify the project or share for which a snapshot was taken, for example "project1:share1" could indicate a scheduled snapshot taken on share1 within project1. Labels can be up to 35 alphanumeric characters and include special characters _ - . :

Project level snapshots are administered in the same way as share level snapshots. For more information about snapshots, see Shares:Snapshots

Project snapshots do not support rollback or clone operations. For more information about snapshots, see Shares:Snapshots

To access the snapshots for a project, navigate to the project and run the snapshots command.

clownfish:> shares select default
clownfish:shares default> snapshots
clownfish:shares default snapshots> 

From this point, snapshots are administered in the same way as share level snapshots. For more information about snapshots, see Shares:Snapshots

Project snapshots do not support rollback or clone operations. For more information about snapshots, see Shares:Snapshots
