Item Name	Explanation
Shared Folder Name	This is the shared folder name. The input condition is as follows: Use 1 to 250 alphanumeric characters (with the exception of \ / : * ? " < > \| = , ;). The character string "$bak" cannot be set to the last characters of the string.
Protocol	This is the protocol type that the shared folder will use.
Oplocks Setting	This is a setting of the Oplocks function to avoid the file access confliction. When the "CIFS" is checked for Protocol, specification is required. When the Oplocks function is enabled, it becomes impossible to use Alternate Data Stream (ADS) though the improvement of the access performance from the client can be expected. When both protocols of CIFS/NFS are selected, it is not recommended to enable the Oplocks function.
Destination NAS Volume to create Shared Folder	This is a selection of the NAS volume in which the shared folder is created. New: Creates a new NAS volume. Existing: Selects from existing NAS volumes.
Volume Name	This is the NAS volume name. When "New" is selected for Destination NAS Volume to create Shared Folder, specification is required. The input condition is as follows: Use 1 to 16 alphanumeric characters (with the exception of ? * ,).
Volume Capacity	This is the NAS volume capacity. When "New" is selected for Destination NAS Volume to create Shared Folder, specification is required. The system area of 300GB is automatically allocated for the NAS volume. The input condition is as follows: Use an integer from 400(GB) to 128(TB). However, the capacity that can be created as a file system varies with the device model and firmware version. Refer to the file system specification described in the ETERNUS Disk storage system manual.
Volume Number	This is the NAS volume number. When "New" is selected for Destination NAS Volume to create Shared Folder, specification is required. When performing the inter-box backup of a NAS volume, specify the same number as REC destination NAS volume. The input condition is as follows: Use 1 to 6 numeric characters. Volume numbers already used are not allowed. However, the maximum specifiable number varies with the number of volumes creatable in the target device and the number of internal volumes. Refer to the volume specification described in the ETERNUS Disk storage system manual.
Select TPP	This is the Thin Provisioning pool in which the NAS volume is created. When "New" is selected for Destination NAS Volume to create Shared Folder, specification is required. When only one Thin Provisioning pool exists, it is automatically selected.
Select NAS Volume	This is a selection of the NAS volume in which the shared folder is created. When "Existing" is selected for Destination NAS Volume to create Shared Folder, specification is required. When only one NAS volume exists, it is automatically selected.

Enter the necessary information, and then click Next.
The Set NAS Backup page is displayed.

Item Name	Explanation
Set NAS Backup	This is a selection for setting a NAS backup. If the NAS backup has already been set, "Yes" is selected automatically.
Destination Volume to backup	This is the selection of whether to create a new NAS backup volume for the backup destination. When "New" is selected for Set NAS Backup, specification is required. New: Creates a new NAS backup volume. Existing: Selects from existing NAS backup volumes. If the NAS backup has already been set, "Existing" is selected automatically.
Select TPP	This is the Thin Provisioning pool in which the NAS backup volume is created. When "New" is selected for Destination Volume to backup, specification is required. It is recommended to select a Thin Provisioning pool different from the Thin Provisioning pool to which the NAS volume is created. When only one Thin Provisioning pool exists, it is automatically selected.
Select NAS Backup Volume	This is a selection of the NAS backup volume for the backup destination. When "Existing" is selected for Destination Volume to backup, specification is required. NAS backup volumes, which are not set for NAS backup and are the same capacity as the NAS volume of the shared folder creation destination, will be displayed. When NAS backup has already been set, the NAS backup volume which has been set will be displayed.

Item Name	Explanation
Using Snapshot	This is the selection of whether to use NAS snapshot. Yes: Select this when using NAS snapshot. No: Select this when not using NAS snapshot. If the NAS snapshot has already been used, "Yes" is selected automatically and this item cannot be changed.
Number of Snapshot Generations	This is the number of snapshot generations to be kept. When "Yes" is selected for Using Snapshot, specification is required. The input condition is as follows: Use an integer from 1 to 128. However, the number of snapshot generations that can be set varies with the device model and firmware version. Refer to the NAS snapshot specification described in the ETERNUS Disk storage system manual. If the NAS snapshot has already been used, this item cannot be changed.
Schedule Setting	This is the configuration of the schedule for collecting the snapshot. When "Yes" is selected for Using Snapshot, specification is required. Cycle: This is the selection of the cycle by which snapshot will be collected. Daily: A snapshot will be collected every day at the time selected in Hours. Weekly: A snapshot will be collected every week on the selected day of the week at the time selected in Hours. On: This is the selection of the day of the week on which the snapshot will be collected. This selection cannot be made in cases when "Daily" has been selected in Cycle. Check the checkbox for the day of the week on which to collect the snapshot. Hours: This is the selection of the time at which the snapshot will be collected. Check the checkbox of the time you wish to collect a snapshot. When an interval of collecting a snapshot is selected, the selected interval time is automatically checked from the start point of zero time. If the NAS snapshot has already been used, this item cannot be changed.
Select RAID Group in which the NAS Snapshot is created	This is the RAID group of the destination where the NAS snapshot volume is to be created. When "Yes" is selected for Using Snapshot, specification is required. When there is only one RAID group, the RAID group will be selected automatically. When the RAID group has already been set, only the set RAID group will be displayed.

Point

The snapshots will be collected based on the time in the ETERNUS Disk storage system.
When the selection for Using Snapshot has been changed from "No" to "Yes", collection of the snapshot will be automatically started.

Information

When "New" is selected for Destination NAS Volume to create Shared Folder, the shared folder is created after completing of the NAS volume creation processing. Therefore, when it failed to create the shared folder, the NAS volume remains. If try to create the shared folder again, select "Existing" for Destination NAS Volume to create Shared Folder and specify the remained NAS volume. If create the shared folder newly from first step, try to create it again after deleting the remained NAS volume. Refer to "6.8.3 Delete Volume" for information on how to delete the NAS volume.
