Back up PRTG data
PRTG writes data to several locations:
- The PRTG program directory (core installation, custom sensors, custom lookups, etc.)
- The PRTG data directory (monitoring configuration, monitoring data, logs, etc.)
- The registry (license key, admin login, IP settings, etc.)
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 PRTG data directory.
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.
Note: Probes 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. However, alerts are not available during this period.
We recommend that you back up the folder Monitoring Database and the file PRTG Configuration.dat. Usually, you must not back up any other files and folders.
