 ***** Restoring odoo account (filestore and database)
 
-There are still some quirks, so be sure:
-
-- to change your current directory to =/opt/apps/myc-deploy=
-  and put your backup file in the same directory
-- your odoo instance should be already up.
-- an odoo base should not exist with the same name prior to restoring
-  if it is the case, =ODOOBASE=odoo && pgm rm "$ODOOBASE" -f && rm -rf
-- to have =admin-password= defined in your =compose.yml=, in your

 *IMPORTANT* you might want to consider the usage of =docker-cutoff= if
 you are restoring a production odoo onto a dev or staging odoo that you
 don't want to allow to go mess around with sending mails or fetching mails.
