At NetBackup 7.x it does run on a client, BUT, at the moment a client can still use vnetd or even bpcd.
What does it do, it sits there waiting for an incoming connection, and then hands it off the the relevant process.
For example, a media server used to connect to a client directly to bpcd, if using pbx, then the media server connects to pbx, and pbx then hands the connection to bpcd.
It is the same on master and media servers. Incoming connections go to PBX and PBX then hand the connection across to another process.
For example, if you run nbemmcmd -listhosts on a media server the connection goes to PBX on the master, PBX then hands the connectio to nbemm
- There should be 3 ports open in these case?pbx ,vnetd and bpcd
- If my pbx port is up and other 2 are down,Will my backup will work?
