Copying Group & Owner Permissions - Not On Replica

Running Unison 2.53.4.Running Ubuntu servers.
Background:
I have a PRF file with the settings to do a replica sync.  Essentially the purpose of the sync is to back up all home folders on the server to a backup server that is offsite.
I have these items in the PRF file:
auto = truebatch = trueowner = falsegroup = falsetimes = truefastcheck = trueforce = /home
Problem:
The replica server is just a basic Ubuntu server install.  The users that are on the main server do not exist on the backup server.
Therefore when replicating, none of the owner and group information copies over because they don't exist.
Is there any way to force it?  Or a way to just force the user/group number?
The concern is if the main server's drive fails, I would be able to copy the user data from the backup server - but I will then have to set all of the ownership data manually.
