Backs up the database. |
SQLDMOBackup_Files |

Notes
SQL Server can back up an entire database, that portion of a database changed after the last backup, one or more operating system files containing table or index data, or the transaction log of a database.
The value of the Action property determines applicability and interpretation of related Backup object properties. For example, if Action is SQLDMOBackup_Files, either the DatabaseFileGroups or DatabaseFiles property must specify filegroups or files backed up.
