NetWorker Module Information
Modules are client software that is loaded on the application server directly, or a proxy client can be used to offload the resource utilization. The proxy client could be on a storage node to allow client direct backup to that node, also.
The backup process is the same as a normal NetWorker backup, except that a backup API specific to the client called gets loaded and sends data to the save command, which sends the data to the storage node.
Recovery is similar, except the recovery command is used to call the API, which then pushes the data back into the application.
Disparate snapshot technologies can all be managed with NetWorker, both the backup and restore.
