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.

From the as yet unpublished (e.g. subject to change) "Upgrade Guide" under "What's New" Data deduplication Data deduplication is a method of eliminating redundant data in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.

I'm curious as to how it functions and would like some info about it.
