You can deploy NetBackup Snapshot Manager for Data Center in a NetBackup media server, but not in a NetBackup primary server.
If you install NetBackup Snapshot Manager for Data Center on multiple hosts, we recommend that each NetBackup Snapshot Manager for Data Center instance manage separate resources. Two NetBackup Snapshot Manager for Data Center instances should not manage the same resources.
If you host the NetBackup Snapshot Manager for Data Center and media server in the same host, do the following for proper functioning of the backup from snapshot jobs:
Assign distinct IPs and NetBackup client names to the NetBackup Snapshot Manager for Data Center and the media server so that they can obtain different NetBackup Certificates. This is required to have different NetBackup host ID certificates for communication. Use the following configuration:
Configure the host with two network adapters.
Edit the
/etc/hostsfile and enter the details as mentioned in the following example:<IP Address MediaServer Host1> < MediaServer Host1> <IP Address NetBackup Snapshot Manager for Data Center Host2> <NetBackup Snapshot Manager for Data Center Host2>
Specify the
MediaServer Host1parameter in the/etc/hostsfile during the Media server installation for the media server name.Similarly select the NetBackup Snapshot Manager for Data Center Host 2 from the
/etc/hostsfile during the NetBackup Snapshot Manager for Data Center installation with a non-default port other than 443.Start NetBackup Snapshot Manager for Data Center and Media services and register it with NetBackup primary server.
If the host name that you intend to use for NetBackup Snapshot Manager for Data Center is already mapped with a media server's host name, you must remove the older mapping. Refer to the Removing host ID to host name mappings section in the NetBackup Security and Encryption Guide.
Once the NetBackup Snapshot Manager for Data Center is registered, ensure that it has a different HOST DB entry.
Before performing the backup from snapshot jobs, perform the following optimization: DISABLE SHM and NOSHM. See: https://www.veritas.com/support/en_US/article.100016170
