How can I recover history from a deleted device? Does any kind of procedure affect the other devices and sensors?
Best regards,
Stefano.

Hi Stephano,
If you delete a sensor / device in PRTG the historic data of the device will be purged as well. The only way to retrieve the data is to restore the historic data from a backup. You'll also need to copy an older version of the PRTG Configuration.dat to the default directory
to restore the configuration of the object. Please bear in mind that all configuration changes done in the mean time will be lost.
Best regards
