Is anyone running TSM 6.1.2.1 and using Deduplication? I built a test server running 6.1.2.0 and had a dedupe ration of 60%
Today I upgraded it to 6.1.2.1 and configured a file dev class copypool. I configured it to dedupe and left it running for a couple of hours. When I returned it had completed but has only found 4% of duplicate data? it has the exact same data as the primary storage pool!
I then created a new 6.1.2.1 server and backed up the same data again and it only found 3% of duplicate data. To me it looks like dedupe is broken in 6.1.2.1. I am going to try downgrading the second server to 6.1.2.0 and see what happens to dedup % after a few backups.
edit: Im running the servers on Windows 2003 sp2
Dell 2950 4GB ram 8 cores.
The test data is file system backups of 8 non-live servers and a static copy of files from a file server.
