I believe, but am not certain, you can achieve the same thing by changing the windows client settings to "based on time stamp" rather than the archive bit.

If you try to do a cumulative after a differentail (or the other way around), nothing has its archive bit in a state that says it needs to be backed up. Unix uses the data/time of the last successfull backup of the policy. Since both would look back to the last schedule of type FULL, they should get the right info. I really never thought of doing it that way.

We are now starting to migrate our "Windows" world into Netbackup and our immediate plan was to implement the same strategy as used in Unix. However, we have found some documentation which recommends not mixing differentials and cumulatives in the Windows arena. I was hoping that someone could clarify this for me, and if possible explain the reasons why.
