how do not perform a backup tasks when connected through a VPN ?

Either set pre-backup command that will check it's a VPN and error out if it is, and set 'not perform backup if pre- script failed', but this will spam log with errors. Or encapsulate schedule and VPN check logic in another script that will trigger windows event when conditions are met, and set the backup schedule to run 'on windows event'.

Thanks dev-anon fur your help.
How to schedule the VPN check logic script that will trigger windows event in a random way?
I need to peform backup of 100 laptops every monday and friday in a time choosed randomly.
With the acronis scheduler I can choose a random time so your first idea can be better but it will spam log with errors. What about to set pre-backup command that will check it's a VPN and if it is, to stop the backup task without errors? Do you think is it possible ?

Scheduling 'on event' and corresponding invoking script is described in

I don't know if there is a way to cancel backup on condition without generating an error.
You can in theory obtain a random value using %RANDOM% variable, but it's 'randomized' at the first call with some linear function of current time with 1 second precision, so if you're going to call it at scheduled time, it's better to call it several times and then use 'sleep' command to make a random delay.

We are distributing a backup policy to all our agents.
The policy set a full backup task to an ASN with the condition "Location's host is available", so I'm sure that when the notebook are outside the corporate network, the backup doesn't run.
Sometimes happen that the notebooks, have a VPN connection to the corporate network: in this situation the Location's host IS available so the backup starts.
How to don't start the backup when the connection is through a VPN ?

Is the "Location's host is available" feature still working in ABR 11.5?
