Greetings of the day!!
Apologies for the delay in response.
As the primary requirement is to backup the Pc's outside the office network.
So to address this query I will supply you 2 possible solution.
1.Install the UDP Agent for windows on the PC using the link below
and perform the local backup of this PC to any shared location .
2.These PC's can connect to office network through VPN - Right
I am asking this in-case you have a UDP Console server and you want to manage these PC from one server.
But over VPN you might encounter slow backup speed.
Hope this helps.
