3.10.1 Backup / Restoration with Web Console

In order to implement backup, it is required that the following NAS backup configurations have been implemented.

Preferences	Configuration Requirements
NAS Backup Volume	The volume is created in the same storage device as the NAS volume The detailed purpose is "NAS Backup" The volume is of the same capacity as the NAS volume
NAS Copy Group	The copy type is QuickOPC
NAS Copy Pair	The copying source is the NAS volume The copying destination is the NAS backup volume

When NAS backup configurations have not been implemented, or when the above configuration requirements of the NAS backup configurations have not been satisfied, implement the configurations of a NAS backup. Refer to "Set NAS Backup" in the ETERNUS SF Web Console Guide for information on the procedures for configuring the NAS backup.

3.10.1.2 How to Execute Backup

Execute backup of the NAS volume with QuickOPC from the Web Console.

Refer to "Backup of NAS Volume" in the ETERNUS SF Web Console Guide for information on the procedures for executing backup.

Information

If a NAS backup volume is mounted, setup values (shared status, access settings, etc.) in the shared folder within the NAS backup volume are setup values for the NAS volume at the time of execution of the backup.

3.10.1.3 How to Execute Restoration

Execute restoration of the NAS volume from the Web Console.

Refer to "Restore to NAS Volume" in the ETERNUS SF Web Console Guide for information on the procedures for executing restoration.

Information

When executing restoration of the NAS volume, it is required that backup has already been implemented. Confirm whether backup has already been implemented by referring to "Display Shared Folder" in the ETERNUS SF Web Console Guide.

Note

If the restore fails, data corruption may be occurring on the NAS volume. Remove the cause of the failure and retry the restore.
The shared folder name must be unique within an ETERNUS Disk storage system.
When the shared folder name is duplicated as a result of the restore operation, a "$" is appended to the start of the shared folder name.

3.10.1.4 Suspending / Confirming Status of Backup / Restoration

Confirming Status of Backup / Restoration

The status of the backup and restoration of the NAS volume can be confirmed from the Web Console.

Refer to "Add/Display/Delete Copy Pair" in the ETERNUS SF Web Console Guide for information on the procedures for confirming the status.

Information

Confirm the copy group belonging to the copy pair by referring to "Display Shared Folder" in the ETERNUS SF Web Console Guide.

Note

There may be cases when the copy status that can be confirmed with the Web Console does not match the success or failure of the backup / restoration of the NAS volume. Determine the success or failure of the backup from the operation history of backup / restoration. Refer to "Display Operation History" in the ETERNUS SF Web Console Guide for the display method of the operation history of backup/restoration.

Suspending Backup / Restoration

Suspend backup / restoration of the NAS volume from the Web Console.

Refer to "Cancel Copy Session of Copy Pair" in the ETERNUS SF Web Console Guide for information on the procedures for suspension.

Information

Confirm the copy group belonging to the copy pair by referring to "Display Shared Folder" in the ETERNUS SF Web Console Guide.

Note

Suspension of the copying from the NAS volume to the NAS backup volume is implemented by the procedures for performing a secondary backup of the NAS volume.
When copying is suspended while physical copying is taking place, even if the backup is a success, the backed up data cannot be guaranteed.
