Back Up the Database Tables
The -b option of the mvsrcid utility provides a means for the system operator to back
up those database tables that are affected by the mvsrcid utility, before the utility is
used to generate source IDs that need to be converted to TV Guide source IDs. While
you do not have to back up the database tables before you update the tables with TV
Guide source IDs, our engineers recommend that you do so. Should something go
wrong when you update your database tables with TV Guide source IDs, your
backed-up database tables will enable you to restore your system.
