About the agentless feature
If you want NetBackup to discover and protect assets on a host, but you want to minimize the vendor software footprint on the hosts, consider Snapshot Manager's agentless feature. Typically, when you use an agent, the software remains on the host at all times. In contrast, the agentless feature works as follows:
The Snapshot Manager software accesses the host through SSH on Linux and WMI and SMB in case of Windows.
Snapshot Manager performs the specified task, such as creating a snapshot.
When the task completes, Snapshot Manager software stops the process.
The Snapshot Manager agentless feature currently discovers and operates on Windows or Linux file system assets, Oracle database and Microsoft SQL database assets.
