NetBackup VMware ports

The TCP ports 443 and 902 are required to access the VMware infrastructure, as follows:


NetBackup connects to TCP port 443 on the following VMware components:

  • On the vCenter server for VM discovery requests, snapshot creation and deletion, vSphere Tag associations, and so on.

  • On the vSphere Platform Services Controller (PSC) to discover, back up and restore vSphere Tag associations.

    NetBackup connects to the vSphere Platform Services Controller (PSC) in vSphere 6.0 and later.


TCP port 902 is required when:

  • You use HotAdd/NBD/NBDSSL transport for backups and restore.

  • Restores are done through Restore ESX server bypassing the vCenter server.
