Dear TSM-ers, We are almost in production with our first directory containerpool TSM server. We did a lot of testing with client vs server-side dedup and overall client-side was faster. But not on one of our Linux clients. This machine has a filesystem with nearly two million files, total amount of data is 227 GB. The server backs up through 1Gb Ethernet and with server-side dedup the backup takes 03:54. With client-side dedup enabled, the backup runs for 12:02! The client contains 16 CPU's and average utilization is no more than 10%. No swapping during a backup. I opened a PMR, but the support offices tries to convince me that client-side dedup is slower (twice as slow) by default. I really have a very hard time believing this. What is your experience with client-side dedup in combination with a large amount of smaller (approx. 1 Mb) files? Thanks for any help in advance!
