Run a full backup to back up both the database file and the transaction log.
The backup copies of the database file and transaction log file have the same names as the online versions of these files. For example, if you make a backup of the database created during installation, the backup copies are called esp_cluster.db and esp_cluster.log. When you repeat the backup statement, choose a new backup directory to avoid overwriting the backup copies.
The following statement creates a full backup of the database in the directory C:\temp\backup:
BACKUP DATABASE DIRECTORY 'c:\\temp\\backup'
