Moving video files automatically over wifi

Hi guys,
my friend has a Huawei phone (not sure of the model) but it's running Android 7. Every month or even less she has the same problem, out of memory messages, because the phone's memory (16GB internal, plus 64GB SD) has totally filled up with video files. She runs a dog charity and rescues many dogs from the pounds in Spain, pays all their vet bills, then finds homes for them all over Europe. She makes lots and lots of videos using her phone so she can send clips, training videos etc. to potential adoptees. She has a Dropbox account and other free cloud storage, but they are usually maxed out too. I normally archive all her free cloud storage to an external drive attached to her laptop, and the files on her phone, using Wifi File Transfer Pro, then the monthly process repeats.

What she would like (and what I would like, to save me all this work), if it is at all possible, is when she comes home after a day of making videos, and the phone connects to her home wifi system, for all the pics and videos on her phone to be automatically moved from the phone to a 5TB external storage drive attached to her laptop, also on the same wifi. This process should be automatic, preferably.

Any suggestions?

Thanks
