What application are you using to get a dedupe ratio of 24:1 on a DataDomain? We've got about 25 DataDomains or DataDomain replication pairs set up; admittedly, we erred on the side of not overloading the front ends. Of those 25 pairs, the only one whose dedupe ratio approaches 20:1 is the one that's that's almost all DB2 full backups. Like many TDP clients, those aren't "incremental forever," the dedupe ratio looks better. For TSM hetergeneous environments, we're seeing ~8:1 on average. 6:1 for planning purposes, 9:1 when we're feeling generous toward our account team. Nick
