Hi Team,
Till now in backup infrastrcutre, i have seen client , master and media server and storage devices can communicate with each other.
there is one query raised.
what if i have situation like;
Clients and media server can communicate
Media and master server can communicate.
but
I wont be ablt to ping client from master server.
Will backup work in these kind of scenarios.
Solved! Go to Solution.

yes.... it will work only if they are File systems bakups schedules from Master servers..
any kind of client request does not work (like restore from client, user backups, DB backups etc.. ) also can not update the configuraitons from Mater server..
but File system backups still work as long as you have the good communication between the media server and client.

Master server contact client to resolve the "ALL_LOCAL_DRIVES" directive I have been told. So backup will likely fail.
Now, just because ping doesn't work, it doesn mean master server can't talk to client. Firewall usually filter off ICMP (ping) packages.
To test for connectivity use Netbackup command bptestbpcd
How to use bptestbpcd:

As mentiioned earlier ping is not necessary the reason for backup failure as ICMP might be disabled
But yes if the other required NBU ports are open then backups should work
You can telnet the bpcd ,vnetd and pbx port to verify if those ports are open

ping is not a NetBackup comms test.
Use this on the master:
bptestbpcd -verbose -client myclientname
Use this on the client to get client to reach out to master and what this does is ask the master to report back to client a response to: "Hey master server, who do you think I am?"
bpclntcmd -pn

Thank you all for the response
In this configuration, i am told that client wont be able to communicate with master server at all.
@Ram,
As you said file system backup will work.
What if i have application backup like exchange, sharepoint, oracle, will that also work?

ALL_LOCAL_DRIVES does work without communications with the master, tested on 7.6.0.4 and 7.7.1 with Windows and Unix clients/policies. It will NOT work if you have multistreaming enabled on the policy.

Expect file system bakups(with out Mulit streaming).. nothing will work...
