    BPDM  (Disk Manager) monitors the backups to and restores from DISK. just as the BPTM handles I/O for TAPE backups and restores.

     BPDBM is  NetBackup database manager daemon that responds to the queries that are related to the NetBackup internal databases (catalogs). BPDBM must be running for NetBackup commands and utilities to work properly.

    In support of above excellent posts - you may want to download the Troubleshooting Guide and read through Appendix A.

    It contains process flow diagrams for backup and restore along with detailed explanation of all processes/binaries.
