In response to: Concerns over DAOS Estimator?
Just a note - I have seen what Vitor is referring to in his comment on my initial post and have verified that there are cases where if the file name is the same as well as the size reported in the DAOS Estimator report that the files are treated as the same object by the Estimator. But after enabling DAOS on the database and compacting it, the two attachments were treated as separate objects by DAOS even though the tool did not see them as different.
This means that you may save less space than the Estimator thinks due to some edge cases where you may possibly have attachments with the same name and physical file size but with different internal data. In Vitor's case with auto-generated files, the results may be very skewed. Again, each environment is different and ymmv. IBM is already aware of these findings above. :)

Chad Scott from IBM support just contacted me regarding this issue and I provided him with what I hope is enough info to reproduce the problem.
