Hi,
It could make sense to sign up for Google Enterprise subscription:
https://gsuite.google.co.uk/intl/en_uk/pricing.html
5 users will cost you 5 x £20 = £100 per month and give 5 accounts with
unlimited storage in a trusted and reliable place.
AFAIK there is upload speed cap in place so it may take you many days to
complete the initial push.
Moving forward I would recommend rsync or similar for differential data
updates.
Not sure why you've posted your question to this list though?
Thanks,
Adam
