Snap shot
Snap Shot detaches the snapshot mirror and creates a new volume that is associated with that mirror. This process takes a relatively short time, typically less than a minute, during which users can be requested not to access the original volume. After the snapshot volume is created, it can be used for backup or other purposes. Snap Shot can also make snapshots of more than one volume at the same time.
Note:
Dynamic disks belonging to a Microsoft Disk Management Disk Group do not support the Snap Shot command.
To take a snapshot
- Right-click on one of the volumes with a snapshot mirror. A context menu is displayed.
- Select Snap > Snap Shot.
- The Snap Shot Volume Wizard Welcome screen appears. Click Next to continue.
- In the Select Volumes window that appears, select the volumes that you want to take a snapshot of.
Highlight the volumes in the Available volumes pane and click Add. Your selected volumes should appear in the Selected volumes pane.
You have the option of taking the snapshot with Volume Shadow Copy Service (VSS). The VSS snapshot method lets you take snapshots of VSS-aware applications, such as Microsoft SQL Server, while the application files are open. When VSS-aware applications do not exist, the snapshot is taken with the SFW FlashSnap method (VM method).
When the VSS snapshot method is used, snapshots can only be taken of read or write volumes and the resulting VSS snapshot is read only. The V snapshot method may take snapshots of read or write or read-only volumes and the resulting snapshots match the access mode of the original volume. However, when the VM snapshot method is used the Snap Shot Volume Wizard presents a Force Read Only check box to let you specify the resulting snapshot to have read only access.
You can set the snapshot process to use the VSS or the VM snapshot method by using Systems Settings.
Click Next after selecting your volumes.
- After editing the attributes, click Next to continue.
In the Change Attributes window that appears, you may edit the following attributes of the snapshot:
Snap Volume Label
Note:
The default Snap Volume Label begins with "SnapV" followed by a 12 character alphanumeric string. The 12 character alphanumeric string is a coded hexadecimal timestamp based upon the time that the snapshot was taken. For example, a default Snap Volume Label would be "SnapV4A7337AE038A".
Note:
The Snap Volume Label cannot be changed for read-only snapshots.
Drive Letter
Plex
- Click Finish in the final window to begin the Snap Shot process.
The snapshot mirror is detached from each of the original volumes, and new volumes are created that are associated with the snapshot mirrors. This process usually takes less than a minute.
The snapshot mirrors are no longer displayed on the Mirrors tab of the original volumes. The new snapshot volumes are displayed under the Volumes folder in the tree view. The program assigns them the next available drive letters (drive letters F and L in the tree view of the following sample screen).
You can now use the snapshot volume for backup or other purposes.
