How do I schedule main database backups?
|
CAUTION Service Disruption |
The disk partition that is to contain the database backup must have sufficient space for the database backup file set, or system performance may be compromised.
Ensure that the backup directory is at least five times as large as the expected database backup size. For more information, contact technical support or see the NSP Planning Guide.

A main database backup consumes considerable system resources.
Ensure that you specify a backup schedule of reasonable frequency, for example, daily.
Note: The NFM-P backs up the Oracle encryption wallet during a database backup, and restores the wallet during a database restore. In a redundant deployment, the NFM-P automatically replicates the encryption wallet from the primary to the standby database after the standby database reinstantiation.
Note: During a database backup, the performance of GUI or XML API operations may be affected. It is recommended that you schedule the database backup to occur during a period of low NFM-P activity.
Steps
1 |
Choose Administration→Database from the NFM-P menu. The Database Manager form (Edit) opens. | ||
2 |
Click on the Backup tab. | ||
3 |
Configure the required parameters in the Backup Schedule panel. Note: You must select the Schedule Enabled parameter. | ||

Before the NFM-P performs a database backup, it deletes the contents of the specified backup directory. Ensure that the backup directory that you specify in this step does not contain files that you need to retain. Configure the Scheduled Backup Directory parameter in the Backup Setting panel. The value that you specify is the database station directory in which to save the backup file sets. Each file set is stored in a subdirectory named backupsetn, where n is a sequential number; the highest possible value is the Number to Keep parameter value. Note: The Oracle management user requires read and write permissions on the backup directory. The user and group names are specified during database installation; the default is ‘oracle’ in the ‘dba’ group. Note: The Scheduled Backup Directory must be a directory on the local file system. | ||

Close the Database Manager form. | ||

After each scheduled database backup completes, move the database backup file set to another station for safekeeping. The database backup creates the following summary file in the same directory as the backup files: BACKUP_SUMMARY.INFO The summary file contains detailed backup information that includes the backup completion time, and the name and size of each backup file.
