Allocate a Management Server to manage the operation side device and the backup side device. Register the operation side device and backup side device in the Management Server.
Create the following volumes in the operation side device and backup side device.
Device | Volume |
|---|---|
Operation side device |
|
Backup side device |
|
Operation side device
Create a NAS volume according to the installation procedures for the NAS operation.
Perform a NAS backup setting to create a NAS backup volume.
Backup side device
Create a logical volume for the REC volumes.
Create a logical volume as the backup volume.
See
For the introduction procedures for NAS operation, refer to "NAS Management" in the ETERNUS SF Storage Cruiser Operation Guide or ETERNUS SF Express Operation Guide.
For the procedure to create a NAS backup volume, refer to "Set NAS Backup" in the ETERNUS SF Web Console Guide.
Note
The volume for REC needs to be assigned a Logical volume of the same capacity as that of the NAS backup volume of the REC source. A Thin Provisioning Volume is recommended for it.
Arrange a volume for REC apart from the backup volume to secure at least a generation of backup data in the backup side.
The copy groups shown below are created.
Copy Group / Copy Pair | Creation Method | Copy Type |
|---|---|---|
Copy group of NAS volume and NAS backup volume | NAS backup settings | QuickOPC |
Copy group of NAS backup volume and volume for REC | Execution of the acgroup create command | REC |
Copy group of volume for REC and backup volume | Execution of the acgroup create command | QuickOPC |
Point
When performing a data protection operation between different sites, arrange a Management Server in each site. Register all the copy groups/copy pairs to the Management Servers to allow execution of all the backup/restore procedures.
Use Stack mode for the REC data transmission mode.
In the case of backup to a tape to use the REC initial copy skip function, direct backup to a tape from the NAS volume or NAS backup volume is not available. Back up to a tape from other secondary backup executed volume. For the secondary backup of a NAS volume, refer to "3.10.5 Concerning Secondary Backup of NAS Volume and Use of Data on Different Storage Devices".
