My statement was a point of reference to a similar technology, which has real world use cases.

IBM presented a paper on how they were at that time planning to implement dedup at the oxford TSM symposium in 2007. That is a very good reference for those people that attended. Also there are lots of people in the 6.1 beta program, they have access to full TSM server code and docs. You are right, if you were not fortunate enough to attend the TSM symposium or join the beta program, you indeed need to speculate, or better, be patient. --Original Message-- From: Remco Post Sender: ADSM: Dist Stor Manager To: ADSM-L@VM.MARIST.EDU ReplyTo: ADSM: Dist Stor Manager Subject: Re: [ADSM-L] TSM 6.x and dedupe Sent: Feb 21, 2009 15:20 On Feb 21, 2009, at 20:49 , Delroy Blake wrote: Until it comes out, one could use diligent Protectier as reference point do you have any indications about any part of the diligent system having made it's way into TSM 6.1?

Re: TSM 6.x and dedupe
Being that TSM 6.1 is still in beta, I wouldn't put much weight on any kind of metrics or performance available with the current load. Everyone also needs to keep in mind that dedupe will only be initially available for storage pools that are FILE-based. DISK- and TAPE-based dedupe will not be available any time soon. -- Mark Stapleton System engineer, CDW -Original Message- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Tyree, David Sent: Friday, February 20, 2009 7:51 AM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] TSM 6.x and dedupe Can users of TSM 6.x comment on it's data dedupe functionality?

Re: TSM 6.x and dedupe
From the as yet unpublished (e.g. subject to change) Upgrade Guide under What's New Data deduplication Data deduplication is a method of eliminating redundant data in sequential-access disk (FILE) primary, copy, and active-data storage pools. One unique instance of the data is retained on storage media, and redundant data is replaced with a pointer to the unique data copy. The goal of deduplication is to reduce the overall amount of time that is required to retrieve data by letting you store more data on disk, rather than on tape. Data deduplication in Tivoli Storage Manager is a two-phase process. In the first phase, duplicate data is identified. During the second phase, duplicate data is removed by certain server processes, such as reclamation processing of storage-pool volumes. By default, a duplicate-identification process begins automatically after you define a storage pool for deduplication. (If you specify a duplicate-identification process when you update a storage pool, it also starts automatically.) Because duplication identification requires extra disk I/O and CPU resources, Tivoli Storage Manager lets you control when identification begins as well as the number and duration of processes. You can deduplicate any type of data except encrypted data. You can deduplicate client backup and archive data, Tivoli Data Protection data, and so on. Tivoli Storage Manager can deduplicate whole files as well as files that are members of an aggregate. You can deduplicate data that has already been stored. No additional backup, archive, or migration is required. For optimal efficiency when deduplicating, upgrade to the version 6.1 backup-archive client. Restriction: You can use the data-deduplication feature with Tivoli Storage Manager Extended Edition only.

Re: TSM 6.x and dedupe
Is the TSM 6.x guide due out next month or april? I assume there will be a New Concepts guide at some point also.
