Problem with poor connectivity between LoRa server and base station

Hi Colleagues, we have a remote Kerlink iFemtocell base station connected via unstable link to LoRa Server. Link can be down sometimes for 24 hours. Is it possible to create a local storage at remote site by connecting it to local router and keep packets sent by tracker until link will be restored? What setup should be done in LoRaWan Server, base station and tracker in order to avoid losing data sent by tracker? Thank you in advance. Regards, Tigran
