Manual Snapshots Using the BUI

There are two types of snapshots; project level and share/LUN level snapshots.

Create a project level snapshot

1. Open the project that you want to snapshot.
2. Click the Snapshots tab.
3. Click the icon. The snapshots list appears.
4. In the dialog box, type a name for the snapsnot.
5. To create the snapshot, click "apply".

Create a share/LUN level snapshot

1. Open the share/LUN that you want to snapshot.
2. Click the Snapshots tab.
3. Click the icon. The snapshots list appears.
4. In the dialog box, type a name for the snapsnot.
5. To create the snapshot, click "apply".

   There is no limit on the number of snapshots that can be taken, but each snapshot consumes memory, so creating large numbers of snapshots can slow the system. The practical limit on the number of snapshots system-wide depends on the system configuration, but should be over a hundred thousand.

Renaming a Snapshot (BUI)

1. To rename a snapshot, click the name within the list of active snapshots. This will change to a text input box.
2. After updating the name within the text input, hitting return or changing focus will commit the changes.

Destroying a Snapshot (BUI)

1. To destroy a snapshot, click the icon when over the row for the target snapshot.
2. Destroying a snapshot will require destroying any clones and their descendents. If this is the case, you will be prompted with a list of the clones that will be affected.

Rolling back to a Snapshot (BUI)

1. To rollback a filesystem, click the icon for the destination snapshot.
2. A confirmation dialog will appear, and if there are any clones of the snapshot, any newer snapshots, or their descendents, they will be displayed, indicating that they will be destroyed as part of this process.

   In addition to accessing the data in a filesystem snapshot directory, snapshots can also be used to roll back to a previous instance of the filesystem or LUN. This requires destroying any newer snapshots and their clones, and reverts the share contents to what they were at the time the snapshot was taken. It does not affect any property settings on the share, though changes to filesystem root directory access will be lost, as that is part of the filesystem data.

Cloning a Snapshot (BUI)

• To create a clone, click the icon for the source snapshot. A dialog will prompt for the following values.

  • Project - Destination project. By default, clones are created within the current project, but they can also be created in different projects (or moved between projects).

  • Name - Type a name for the clone.

  • Mountpoint - To use this value, click the lock icon. Set the mountpoint for the clone. When Retain Other Local Settings is set, the clone must be given a different mountpoint, as shares cannot save the same mountpoint.

  • Resource Name - To use this value, click the lock icon. Enter the resource that you want to use for the clone.

  • Retain Other Local Settings - By default, all currently inherited properties of the filesystem will inherit from the destination project in the clone. Local settings are always preserved. Setting this property causes any inherited properties to be preserved as local setting in the new clone.

  A clone is a writable copy of a snapshot, and is managed like any other share. Like snapshots of filesystems, it initially consumes no additional space. As the data in the clone changes, it will consume more space. The original snapshot cannot be destroyed without also destroying the clone. Scheduled snapshots can be safely cloned, and scheduled snapshots with clones will be ignored if they otherwise should be destroyed.
