SEPM 12.1 Database Backup

I have a SEPM 12.1 console with a SQL Server 2008 database instance. Previously we backed up the database by exporting SQL backups via SQL Server Management Studio. Currently we have it backing up by selecting the 'Database Backup' option in the SEPM. I'm wondering what the pros or cons are of each and if one is better than the other. I see that most Symantec articles reccomend backing up the database from the SEPM but wondering if the export options is sufficient. Thanks.
