Importing Database Archives

3 April 2019 Forum By: Darragh Delaney

If you want to analyse network traffic data that is no longer available online and if you have backup enabled, you can import archived data back into a LANGuardian reader system.

When LANGuardian is deployed and fills its disk, it will create archive files of old data which can be exported automatically (by using the Enable Backup settings). When it comes to a time when these archives need to be accessed, most customers are wary about importing them into their live system as they will fill up the disk again.

This import feature and a LANGuardian reader system is useful in situations where you need to investigate past events such as file deletions or Internet downloads.

To do this, it’s necessary to create a separate LANGuardian (Reader) instance which will allow the archive file/s to be uploaded to it. It’s not possible to upload archive files to a production system and it would not be recommended in any case.

This separate LANGuardian system will require what’s known as a ‘Reader’ license, which we provide, on request. Email us at

When this license is applied and you navigate to the LANGuardian settings page, you will see a new option: Import Database archive

Click on this option > navigate to the .dat archive file and upload it:

You can click on ‘Show advanced options’ to select specific categories that you want to include in the import:

Now, go to any report and run for the time frame of the archive files you uploaded. For example:

After you import the data, it will become available through the LANGuardian Reader user interface and be included in all of the existing dashboards, reports, and trends. If you want to focus specifically on the imported data, you might need to create custom reports that focus on the dates covered by the archive.
