I've been reading up on the documentation for backing up a NetApp NAS in cluster mode via NDMP.
My environment is 7.5.0.6, with RH Linux master and media servers, backing up to Data Domains. My storage admin wants to know if we can backup via the virtual hostname of the cluster (I assume that to be the vServer name).
Based on what I've read, the options are:
- backup the volumes by physical node, in which case any failover would result in a change on the NB DNMP policies.
- backup using LIFs (recommended) where a failover woud require an action on the part of the storage admin to change the lif to point to the proper physical node.
- backing up using the vServer as the NDMP host.
That last one is where I'm a bit confused. We only have one vServer with 2 nodes for testing. If I'm going this route, where would the physical node come into play in the policy setup, since in one of the docs it states:
"Because NetBackup has not yet implemented the CAB extension, the storage administrator must tell the backup administrator to modify the policy for the volume(s) moved to another node. The storage administrator will likely be aware of the failover and can also notify the backup administrator to modify policies related to the failover."
Also, since I am doing 3-way NDMP, writing to DD via a media server using boost (no VTL), I assume each option is available to me.
Thanks
