Did you have to change your "Keep TIR Information" to longer than 1 day in your Master server properties to get this to work?

When the incrementals are assembled, the changes are reflected in the new synthetic full. I just tested this to see for myself. (ver 6.5) I believe this feature is enabled (and required) in the policy under the label "collect true image restore information" and "with move detection". I moved a subdirectory to a new directory level, and the incremental backed up the entire contents of that moved data. It isn't smart enough to see that the files were same just moved to a new home. Maybe de-duplication will handle this in future versions. -Jon > You need to run a differential and then a synthetic full immediately > following.
