IBM adds dedupe to Tivoli Storage Manager
IBM has announced a major release of its Tivoli Storage manager backup, archive and compliance product, adding scalability to up to a billion data objects, up to 3X faster backup speeds, and de-duplication.
TSM 6.0 has an integrated DB2 engine that doubles the number of storable data objects with the potential to manage a billion objects in a single system and speed backups by up to 300 per cent. It claims one customer found some jobs that would have taken three or four hours can now be done in 30 minutes.
TSM 6 Extended Edition offers what IBM calls data reduction technologies - de-duplication to you and me - understood to be based on Diligent technology. IBM acquired Dilligent in April last year for a rumoured $200m.
Strangely IBM, keen to quantitatively impress us with DB2 engine integration benefits, provides no guidance for raw to de-duplicated data ratios at all - no cited customer experiences here. It's almost as if IBM wants to downplay its data reduction capabilities.
