cloud shared drives etc

[Ish]

Hi

For a small setup of 5 users who have no server what would be the best/easisest/cheapest way for them to have different shared drives with permissions etc.

At the moment if they use a different pc they can't see their files etc.

Would it be some sort of cloud service?

For something like a Synology what are the options for backing this up in the cloud?
