Backup of a windows server behind Fortinet firewall

I have been trying to setup backup of an offline Windows server to Google Cloud so I would like to know what is the minimal traffic I would need to allow to pass through our firewall.

Also does anyone have experience working with a Fortinet firewall on this? We want to only allow traffic initiated by CloudBerry but can’t seem to find the application in Fortinet’s list.

[reply=“Sharon Y;d1247”] Adding our .exe and GC endpoint to exclusions manually should actually be enough. Hope that there are more experienced Fortinet users on the forum to add something to the thread.
