9.1 Database Backup Tool
With the database backup tool, you can back up and restore the DMS database to protect thedata.
With this tool, you can also maintain the NMS database remotely to make the backup andrestoration operation conveniently.
The basic functions of the database backup tool are as follows:
z Viewing Information
You can view the general information of the DMS database and logs operated by thebackup tool.
z Configuring Parameters
You can set the parameters for the backup, including the Backup Device, Database Setand Auto Backup Policy.
z
Performing TasksYou can back up and recover the database, including Manual Backup, Auto BackupTaskand Restore Database.
The database backup tool is provided as a stand-alone component. This function is supported only whenthis component is selected during the installation of the DMS.
9.1.1 Backup Policy
The database backup tool supports two backup policies as follows:
z Manual backup
z Scheduled (automatic) backup
Every day: The system backs up data every day.
Every week: The system backs up data on a specific day every week.
Every month: The system backs up data on a specific day every month.
9.1.2 Backup Medium
The database backup tool backs up data to:
z Disk
z Tape
9.1.3 Backup Path
For the disk backup, the default backup directory of the DMS is $N2000ROOT/backup.
In the same database set, up to n (4 by default) backup data files can be stored.
In the same database set, the maximum times of data backup are four. If exceeds four, the systemprompts you whether to delete the earliest backup and add a new backup.
