3.10.4 How to Access Backup Destination Volume

If the NAS backup volume used as backup destination is mounted, it is accessible in Read-Only mode.

The section explains how to access the NAS backup volume:

Access Using CIFS Protocol

The NAS backup volume is accessible by the Windows file sharing or network drive mapping.

Enter the following format to the address bar or to the network drive mapping window:

\\nasInterfaceIpAddress\sharedFolderName$bak

To access the home directory under "homes", the shared folder on the NAS backup volume, enter the following format. The folder "homes$bak" is accessible with the user set in Owner and Group.

When Active Directory is configured as an authentication server
```
\\nasInterfaceIpAddress\homes$bak\domainName@\userName\
```

When no authentication server is configured

\\nasInterfaceIpAddress\homes$bak\userName\

When authenticating by Active Directory, the operation method varies depending on the presence of setup of an authentication server.

If Active Directory is configured as an authentication server
Enter the user name and password registered to Active Directory.
When connecting from the client participating in Active Directory, authentication is not needed.
If an authentication server is not set up
Enter the user name and password described in the ETERNUS Disk storage system manuals or local user name and password registered in the ETERNUS Disk storage system for connecting to NAS.
Information
Entering the IP address for NAS interface in the address bar can view sharable folders.
Note
When multiple NAS backup volumes are mounted, it may not be possible to confirm shared folders with duplicate names. In this case, mount the NAS backup volumes individually.

Access Using NFS Protocol

The NAS backup volume is accessible by performing the NFS mount from a UNIX server using the following procedure:

When authenticating through LDAP, there is no difference in operation method with the presence of setup of an authentication server. Make the UNIX server participate in the LDAP domain to perform the NFS mount.

Check the volume number of the NAS backup volume.
The volume number is displayed in the NAS Backup Volume No. in the Basic tab of the Detail Shared Folder screen.
For the procedure to display the Basic tab of the Detail Shared Folder screen, refer to "Display Shared Folder" in the ETERNUS SF Web Console Guide.
Log in to the UNIX server with administrator privileges.
Execute the mount command to mount the shared folder.
When executing the mount command, specify the following:
[For Solaris]
```
mount -F nfs nasInterfaceIpAddress:/mnt/nas/nvnasBackupVolumeNumber/data/sharedFolderName mountDestinationDir
```
[For Linux]
```
mount -t nfs nasInterfaceIpAddress:/mnt/nas/nvnasBackupVolumeNumber/data/sharedFolderName mountDestinationDir
```
Information
Executing the showmount command on the UNIX server can view NFS mountable shared folders.
```
showmount -e nasInterfaceIpAddress
```
After NFS mounted, logging in to the UNIX server as the user registered to LDAP can access the shared folder with the owner/group permissions set to the shared folder.
When not authenticating through LDAP, logging in to the UNIX server can access the shared folder.
