Run the TSF Database Backup

Important! We recommend that you schedule the TSF database backup job to run regularly, with more frequent backups during system setup.

Follow the backup policy for your site, and consult with your system administrator.

Follow these steps:

Verify that the setup for the TSF database backup is complete. See Prepare the TSF Database Backup.
Verify that you have BPX.SUPERUSR authority. This authority is required to unmount the databases later in this procedure.
Stop the TSF Server (CHORNTSF started task):
```
P CHORNTSF
```
Unmount the TSF Server database:
```
unmount INSTALL_HOME/database/ntsf
```
Run the JCL member for the TSF database backup. This JCL member was created in Prepare the TSF Database Backup.

Remount the TSF Server database:

mount -t ZFS -f ‘chorus_runtime_hlq.CETJNTSF’ INSTALL_HOME/database/ntsf

Restart the TSF Server (CHORNTSF started task):
```
S CHORNTSF
```
You have created a backup of the TSF database.
