I would not treat e-mail specially, but simply use a de-duplicating incremental backup strategy that takes care of it like everything else.

It provides compression too. best, Tamás On Tue, Mar 14 2023, H wrote: > I am trying to consolidate multiple backups I have of several of my > email accounts.
