This video shows a high-level inter-process communication and data flow of a typical NetWorker scheduled backup to a Data Domain device.
1.The server’s nsrd starts a scheduled backup. nsrd asks nsrjobd to send a remote execution request to the client’s nsrexecd, requesting that it execute the NetWorker save command to perform the backup.
2.The save command started on the client communicates with the server’s nsrd (through nsrjobd) to request backup support.
3.nsrd requests nsrsnmd for backup support, nsrsnmd matches the backup to a storage node’s nsrmmd based on configuration information and save request attributes.
4.Once the volume has been mounted on the backup device, nsrd directs the client to push its data to the storage node.
5.The client:
Pushes the data to the storage node’s nsrmmd
Sends tracking information to its client file index (CFI) via the server’s nsrindexd
6.nsrmmd on the storage node:
Writes the data sent by the save command to the volume
Sends tracking information to the media database via the server’s nsrmmdbd
