Without the for proxy_update clause, the behavior of the with default_location clause is the same as that provided by sp_defaultloc—a default storage location is established for new and existing table creation, but proxy table definitions are not automatically imported during the processing of create database.
If for proxy_update is specified with no default_location, an error is reported.
Provide an estimate of the database size required to contain all proxy tables representing the actual tables and views found in the primary server’s database.

Create all proxy tables representing the actual tables and views found in the companion server’s database.
Grant all permissions on proxy tables to public.
