I have been reading the threads on the TDP for Exchange and I have a different question. Since Mark Remeta has stated a very good point, my question references the same issue, "single instance storage".

Mark How does an incremental backup for TDP for Exchange work? Since Tivoli does not backup individual mailboxes as files but instead does a Directory and Information Store backup, would a single message sent or received constitute an Information store change, therefore resulting in a complete backup instead of the selected Incremental backup? Or, is the TDP designed to recognize only the changes and only backup those parts of the Information Store that have changed with the possibility of a restore only if you have at least one good Full backup? I am only asking because we currently have 3 Exchange 5.5 servers with 40GB average databases doing nightly full backups. Will going to a 6 day Incremental 1 Full be beneficial with our current retention settings (as follows)? Versions Data Exist 30 Versions Data Deleted 0 Retain Extra Versions 30 Retain Only Versions 30 Also, do these retention settings seem OK. I was not involved with Tivoli when they were set and would value another opinion. Thanks to all, Mark Bertrand
