BPCD Connect-back

The BPCD Connect-back property specifies how daemons are to connect back to BPCD (the NetBackup Client daemon):

• By using a Random Port: NetBackup randomly chooses a free port in the allowed range to perform the traditional connect-back method.
• By using the VNETD port: This method requires no connect-back. The VERITAS Network Daemon (vnetd) was designed to enhance firewall efficiency with NetBackup during server-to-server and server-to-client communications.

For example, when a media server running bpbrm initially connects with a client running bpcd, the situation does not pose a firewall problem because bpbrm is using the well-known bpcd port.

This property appears for master and media servers only.
