PRTG data backup

PRTG Network Monitor writes data to several locations:

• The program directory (core installation)
• The data folder (monitoring configuration, monitoring data, logs, etc.)
• The registry (license key, admin login, IP settings, etc.)

For more information on where PRTG stores its data, see the PRTG Manual: Data Storage.

Quick backup of configuration files

For a quick backup of only the monitoring configuration (for example, groups, devices, sensors, users, maps, reports), back up the file PRTG Configuration.dat in the data folder.

It is also a good idea to back up older configurations in the folder \Configuration Auto-Backups.

These files are not kept open while the PRTG core server is running and can be backed up at any time.

Backing up all data stored in the file system

To get a complete and consistent backup of the databases (for example, log database, monitoring database, Toplist database, Ticket database), stop the PRTG core server while running the actual backup process.

Probes will continue to monitor their sensors for a few minutes and deliver monitoring results to the PRTG core server as soon as it is back online, but alerting will not be available during this period.

Our tip: Most important are the folder Monitoring Database and the file PRTG Configuration.dat. Other files and folders can usually be left out of your backup process.
