Just a note that the below idea works! Here is tutorial config for setting
up both local delivery AND remote forwarding. I guess this is really easy:
Put the text below (with your modifications) in a file, preferably in the
same directory where other Postfix configuration files are.
smtpd_recipient_restrictions =
permit_mynetworks
permit_sasl_authenticated,
reject_unauth_destination

My personal server is happily managing virtual mail domains without any

If 'hot backups' make any sense at all. Oracle online/hot backups
just crossed my mind where we won't lose a single transaction/data
by using point-in-time restore/recovery. Any such equivalent backups
for postfix mail queues?
Or would rsync via ssh to another server help in this case ( without
shutting down postfix).
In Oracle online backup, a good snapshot backup is taken followed
by roll-forward backups where new writes/updates to the database
is separately written to another file sitting on another disk
