Firewall Question..
Client is behind the firewall,master server is not able to resolve it or ping it.
Media server is able to resolve the client name as it is permitted to access the client.Will the backup run ?
...
It will run as long as you don't have ALL_LOCAL_DRIVES defined as your file selections for backup. If you do, then the Master MUST have access to resolve and communicate to the client, as it requests the client to run bpmount to find the filesystems/drives to back up. If you are definining your file selection (i.e. C:\ D:\ or if unix / /var etc) then the Master doesn't have to communicate to the client at all, just the media server.
It's good practice to have the master communicate with the clients though, means you can make changes via the GUI to client settings.
I also believe database backups (SAP, Oracle, SQL) also require Master to have access, though I'd have to read the documentation to be 100% certain.
Hope this helps.
