First of all I'm sorry If I'm asking this question in the wrong place.
I'm curious about how the backup tool on outlook 2003 works. Does this tool automatically copies the whole pst file or checks the pst file for changes and only add the changes to the backup pst.
I'm asking this because I want to learn if this tool tries to copy a 2GB(or larger) sized pst file as a whole or just make changes on it.
Thanks.
