The SLP manager (nbstserv) checks if the duplication window is open to submit duplication jobs. When it finds an SLP window open to submit a duplication job, it will process the relevant images managed by the SLP policies, batch them, and submit them to nbpem for further processing.

nbpem also checks if the SLP window is still open for the duplication operation. If it is, nbpem creates the duplication job structure and submits it to nbjm.

nbjm requests resources as it would for backups (not shown in the figure), and then invokes bpduplicate.

bpduplicate starts the required bpdm and/or bptm processes, media load operations occur (not shown in the diagram), the image is read from the local source storage, and then written to the local destination storage.

After the media server bpdm/bptm processes the exit, bpduplicate also exits.
