University or Manor Road VPN https://help.it.ox.ac.uk/network/vpn/index https://it.socsci.ox.ac.uk/vpn

FileCloud (Staff only)
Access to Home (and/or Shared) Areas over VPN https://it.manor-road.ox.ac.uk/remote-access/can-i-access-file-storage-on-my-own-device.html
Each of these allows use of your device to access University and department resources from your laptop.
