Restore Configuration From PRTG's Auto-Backup

PRTG automatically saves a daily backup of its configuration file in the \Configuration Auto-Backups sub folder of the data folder.

In order to restore a previous configuration from PRTG's auto-backup please follow these steps.

1. Stop both PRTG services:
   • Open the PRTG Probe Administrator program and in the Start/Stop tab, click the Stop Probe Service button.
   • Open the PRTG Server Administrator program and in the Start/Stop tab, click the Stop Core Service button.
2. Open the PRTG data folder
   • For more information on where to find this please see How and where does PRTG store its data?
3. Your current configuration file's name is PRTG Configuration.dat. Please rename it.
4. In the Configuration Auto-Backups sub folder, locate the ZIP file with the configuration you want to restore. Unzip and copy it to the data folder to replace your current configuration.
5. Restart both PRTG services:
   • Open the PRTG Probe Administrator program and in the Start/Stop tab, click the Start Probe Service button.
   • Open the PRTG Server Administrator program and in the Start/Stop tab, click the Start Core Service button.

Done. PRTG is now running with the new configuration.

Note: If you're looking for the last working configuration (e.g. after a crash), repeat the steps above and go back date by date until you obtain a valid configuration again.
