Not sure of any relationship here between poster and the software? But if it is just "backing up" vs migrating to another different mail system - nothing more is needed than copy the entire "MAIL" directory and paste it somewhere safe. Or the entire PMAIL directory.

One of Pegasus's great strengths is how simple this is. You could then reinstall Pegasus on any machine as long as the root directory structure is the same, and just copy all back to that location.

Heads up about DRS Pegasus Converter. Their website states as a pre-requisite tp installing it that you disable anti-virus and add the product to its exception list. This is scary. There is nothing involved in backing up Pegasus Mail that should require this.
