Big Points for ADINT/TSM
ADINT/TSM seamlessly integrates SAP DB with IBM Tivoli Storage Manager (TSM)§ complete set of SAP DB functions for backup and restore, such as
• Full, incremental, log• Restore/recover• Online/offline
§ professional storage management through TSM, such as• storage hierarchies (high performance to low cost)• media management, e.g. expiration, reclamation• tape library control
§ additional functions, see section functional highlights
to provide a dependable, automated and performant base for production-oriented backup/restore processes
