TDPO--> TIVOLI DATA PROTECTION FOR ORACLE
- Tivoli Storage Manager (TSM) is the main software.
- Data Protection (There are multiple for different dbs' Oracle, SQL Server etc) is specifically for backing up and restoring the databases.
- You can't install TDP without TSM installed first, TDPO is a component of TSM
- TDPO provides an interface between RMAN API & TSM API
- With TDPO, RMAN controls how the backups are stored, maintained on storage(TSM)
- WITH TDPO, DBA doesn't need to know the commands used by TSM to backup, maintain files on tape(storage)
- RMAN controls removal of expired backups (TSM policy doesn't govern rman backups)
- Oracle backups (oracle objects) are considered active from TSM perspective
