This is a screenshot taken of a windows agent job:

In this case the third Action is "Network traffic will be encrypted".
This is a screenshot taken of a linux agent job:

The Action "Network traffic will be encrypted" is missing. Both, the windows and linux machine are outside the local network reachable only by a public IP.
Does the Linux Agent just dont print this action out or is it in fact transmitting without encryption?
If it is not printing out that Action, is there any way to check the backup traffic gets enrypted?
