NetWorker 9.0 Avamar integration changes

Beginning with NetWorker version 9.0, support for EMC Avamar integration is deprecated for new clients. However, older integrations continue to be supported with the following considerations.

Changes to this integration with NetWorker 9.0 onwards

Considerations for the integration

• After you upgrade the NetWorker server to version 9.0, clients before 9.0 can continue to perform deduplication backups and recoveries. If you are an existing client and you have upgraded to a 9.0 client, then install the Avamar client to perform deduplication backups and recoveries.
• If the NetWorker server and the NetWorker client are the same hosts, and are upgraded to 9.0, then install the Avamar client to perform deduplication backups and recoveries.
• After you upgrade the NetWorker server to version 9.0, you cannot configure a new Avamar deduplication node. As a result, you cannot configure any new NetWorker clients with deduplication enabled.
• Install the NetWorker client rpm on the Avamar server node. Do not install the Avamar client package on the Avamar node.
• The NetWorker client no longer supports RedHat 4.0. However, Avamar 7.0 can be installed on RedHat 4.0. If you install the NetWorker 9.0 client package on the Avamar server which is on RedHat 4.0, the installation fails. In this case, you can leave the current NW Client version as is. You can still upgrade the NW server and NW deduplication client to NW9.0 and continue backup and recovery using the Avamar server that still has a pre-NW9.0 client package installed.
• This solution does not support IPv6.
• EMC Avamar version 7.2 uses an encrypted port 29000 as the default port, as a result, the NetWorker and Avamar deduplication backup fails. Set the port to an unencrypted port 27000, for the NetWorker and Avamar deduplication to backup correctly. To make this port change, perform the following steps:
  1. On the Avamar server, create a file named gsan-port under the directory/usr/ local/avamar/lib/admin/security/ with the content as follows:

     <avamar server hostname>:~/#: cat /usr/local/avamar/lib/admin/security/gsan-port
     GSAN_PLAIN_TEXT="27000,"

  2. Type the following command to restart the Avamar firewall:

     service avfirewall stop
     service avfirewall start

  3. Type the following command to restart NetWorker:

     /etc/init.d/networker stop
     /etc/init.d/networker start

Existing users of this feature

Existing customers using this feature can continue to refer to the EMC NetWorker Avamar Devices Integration Guide version 8.2 Service Pack 1.

The NetWorker software installation packages includes the Avamar client software. The Avamar client software only provides support to NetWorker hosts that used an Avamar system as a data protection target with a previous release of NetWorker. You can only install the Avamar client software when you upgrade a NetWorker 8.2.x and earlier host. The EMC NetWorker Updating from a Previous Release Guide provides more information.
