Veritas Access Appliance Solutions Guide for NetBackup

Support for multiple domains across networks for Veritas Data Deduplication

You can use a single deduplication pool to back up data from multiple NetBackup domains. The Veritas Data Deduplication server deduplicates backups originating from different subnets. Use the network ip addr show command to list the multiple subnets that have been created.

Network> ip addr show
IP 												Netmask/Prefix 	Device Node 				Type 				Status
-- 												-------------- 	------ ---- 				---- 				------
192.168.10.5 		255.255.255.0 		eth5		 vaupg_01 Physical
192.168.10.13 	255.255.255.0		 eth5 		vaupg_02 Physical
192.168.30.2 		255.255.255.0 		eth4 		vaupg_01 Physical
192.168.30.10 	255.255.255.0 		eth4 		vaupg_02 Physical
10.209.192.206 255.255.252.0 		eth1 		vaupg_01 Physical
10.209.192.208 255.255.252.0 		eth1 		vaupg_02 Physical
10.209.194.38 	255.255.252.0 		eth1 		vaupg_01 Virtual 	ONLINE (Con IP)
192.168.10.22 	255.255.255.0 		eth5 		vaupg_01 Virtual 	ONLINE
192.168.10.25 	255.255.255.0 		eth5 		vaupg_02 Virtual 	ONLINE
192.168.30.15 	255.255.255.0 		eth4 		vaupg_02 Virtual 	ONLINE
192.168.30.20 	255.255.255.0 		eth4 		vaupg_01 Virtual 	ONLINE

You can use the following command to configure the deduplication server with a virtual IP.

Dedupe> config fs_dedupe IPaddress root

For example:

Dedupe> config fs1 192.168.10.22 root
Enter Password:
ACCESS dedupe INFO V-493-10-0 configuring deduplication server...
ACCESS dedupe INFO V-493-10-0 Deduplication server configured successfully

You can verify that the IP has been added successfully using the dedupe show command.

Dedupe> show
Parameter Value
======================= ======
Percentage_Memory_Usage 4.58%
Hostname vaupg_01
Max_Cache_Size 50%
Server_Status ONLINE
Virtual_IP 192.168.10.22
Filesystem fs1
Deduplication_Storage_Size_GB 50

You can add another IP from a different subnet.

Dedupe> addip <IPaddress>

For example:

Dedupe> addip 192.168.10.25
ACCESS dedupe INFO V-493-10-0 IP has been successfully added to the 
deduplication server.
Dedupe> addip 192.168.30.15
ACCESS dedupe INFO V-493-10-0 IP has been successfully added to the 
deduplication server.

Dedupe> addip 192.168.30.20
ACCESS dedupe INFO V-493-10-0 IP has been successfully added to the 
deduplication server.

You can verify that the virtual IP is added successfully. The dedupe show command is used to display information about the deduplication server that has been configured. The output of this command includes the file system(s) being used, deduplication server status, storage capacity, secondary IPs used, percentage of memory usage, maximum cache size, and the IP and the cluster node on which the server is running.

Dedupe> show

Use the network ip addr show command to list the multiple subnets that have been created.

Network> ip addr show
IP 												Netmask/Prefix 	Device Node 				Type 				Status

192.168.10.5 		255.255.255.0 		eth5		 vaupg_01 Physical
192.168.10.13 	255.255.255.0		 eth5 		vaupg_02 Physical
192.168.30.2 		255.255.255.0 		eth4 		vaupg_01 Physical
192.168.30.10 	255.255.255.0 		eth4 		vaupg_02 Physical
10.209.192.206 255.255.252.0 		eth1 		vaupg_01 Physical
10.209.192.208 255.255.252.0 		eth1 		vaupg_02 Physical
10.209.194.38 	255.255.252.0 		eth1 		vaupg_01 Virtual 	ONLINE (Con IP)
192.168.10.22 	255.255.255.0 		eth5 		vaupg_01 Virtual 	ONLINE (Dedupe IP)
192.168.10.25 	255.255.255.0 		eth5 		vaupg_01 Virtual 	ONLINE (Dedupe IP)
192.168.30.15 	255.255.255.0 		eth4 		vaupg_01 Virtual 	ONLINE (Dedupe IP)
192.168.30.20 	255.255.255.0 		eth4 		vaupg_01 Virtual 	ONLINE (Dedupe IP)

You can also add a second user. The second user is used to add the second NetBackup domain, if required. You should use a different user for every new NetBackup domain.

Dedupe> adduser root2
Enter Password:
Confirm Password:
ACCESS dedupe INFO V-493-10-0 Adding new user root2 to deduplication server...
ACCESS dedupe INFO V-493-10-0 Added new user root2 to deduplication server successfully.

You can perform backup and restore operations from the NetBackup domains from the two subnets.

Dedupe> removeip IPaddress

For example:

Dedupe> removeip 192.168.30.15
ACCESS dedupe INFO V-493-10-0 IP has been successfully removed from the 
deduplication server.

You can verify that the second virtual IP has been removed from the configuration using the dedupe showcommand.

Dedupe> show

You can use the dedupe unconfig command to free up all the virtual IPs added to the deduplication server. This command also unconfigures Veritas Data Deduplication from the cluster

Dedupe> unconfig
ACCESS dedupe INFO V-493-10-0 Removing deduplication server configuration...
ACCESS dedupe INFO V-493-10-0 Deduplication server unconfigured successfully.

You cannot use the same virtual IP for both the CIFS and Veritas Data Deduplication server. So, if a virtual IP is used by the Veritas Data Deduplication server, then you cannot use the same virtual IP for adding CIFS shares or setting the CIFS home directory.

During the upgrade, the virtual IP which is shared between CIFS and Veritas Data Deduplication server is removed from the CIFS configuration and the next available free virtual IP is assigned to the CIFS server.
