@Mostafa67 looks like the Exchange DAG name is not resolving in DNS or hosts files

Jun 26, 2023 6:07:00 PM - Error bpbrm (pid=17916) bpcd on Exchange exited with status 48: client hostname could not be found

Add host entries of Exchange DAG name and Node names onto NetBackup Master and Media.

Also add host entries of NetBackup Master and Media name onto all Exchange DAG Nodes and Exchange Cache Server.
