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.
"NetBackup Shared Capacity License (SCL) is a licensing metric based on the total amount of protected front-end data (in Terabytes) across the entire backup environment, regardless of the number of backup clients, servers, or virtual machines. Under this model, a single SCL pool is shared among all NetBackup clients and media servers. Backup data is measured collectively, and capacity consumption is calculated based on the source-side data volume selected for backup jobs. The SCL model simplifies licensing for large-scale, dynamic, or virtualized environments where traditional per-client or per-socket licensing may be inefficient." netbackup scl
This mode represents the older style of communication. It relies on host-based trust and minimal authentication. Under this model, a single SCL pool is
This is the standard for modern NetBackup deployments (often referred to in the context of and hardened appliances). It relies on host-based trust and minimal authentication
Lists the versions of operating systems (Windows, Linux, Unix, etc.) that NetBackup supports for both the server and client components.
If issues arise, knowing what's supported can help in diagnosing and resolving problems more efficiently.
