Thank you for a reply.
I fully understand your concern, but I can assure, that Teltonika Networks do not use any of backup information and handle all clients given information with high level of confidentiality.
In this certain case, backup file was asked, because I was unable to replicate same issue.
I tried to generate a backup file with a RUTX11, which is used daily and have several VPN configurations, multiple profiles and other custom configuration, but was unable to receive backup file bigger than 400 KB.
I am glad, that at the moment, you was able to solve this issue.
If you will need our assistance again, feel free to contact us.
