Scl: Netbackup

If you see status code 150 (or similar connection termination errors) in your job details, it is often an SCL issue. This usually means:

Details cloud platforms and services (AWS, Azure, Google Cloud, etc.) that can be used with NetBackup for cloud backups.

Veritas appliances often come with SCL settings locked down to the highest security standards by default. If you attempt to connect an older, unpatched client to a hardened appliance, the appliance will reject the connection because the older client cannot meet the required Service Connectivity Level.

Veritas introduced the SCL framework to enforce . It ensures that before a backup agent (like bpcd or bprd ) accepts a connection, it validates that the connection is coming from a trusted source using secure certificates (PKI). If you see status code 150 (or similar

Maintaining a current backup environment requires verifying that every component—from the Primary Server to individual clients—is compatible. The SCL prevents "unsupported configuration" errors during critical recovery operations.

Think of SCL as a security dial. Depending on where you set that dial (either explicitly or via the default security configuration), you are telling NetBackup how strictly it should verify the identity of the machine trying to connect. Veritas appliances often come with SCL settings locked

This is the standard for modern NetBackup deployments (often referred to in the context of and hardened appliances).

In the past, NetBackup relied heavily on simple host name resolution and trust relationships. If a server said, "I am Server A," the master server generally believed it.
