Process description

About NetVault Backup processes

NetVault Backup includes several static and dynamic processes that run on the server and client machines.

The static processes remain active while the NetVault Backup Service is running. These processes are assigned fixed single-digit process ID numbers and generally use the same amount of system resources during their life.

The dynamic processes are initiated and destroyed according to the current NetVault Backup activities. These processes are assigned changing ID numbers and use varying amounts of system resources during their life.

On Windows-based machines, you can view the NetVault Backup processes from the Task Manager. On Linux- and UNIX-based platforms, you can use the following command to view these processes:

ps -ef | grep nv
