OneDrive for Business for Workgroup Collaboration
Cloud drives are at their best for workgroup collaboration. This means being able to share one or more folder structures across a distributed workgroup who may or may not be online (e.g. sales teams across the country, often in planes).
Box is great at this. SugarSync does it well too. This is really needed for OneDrive to be useful for Business.
For backup issues you can actually try using "Ahsay software" i am basically using this software from long time and really satisfied using this software. Before making any changes you should first make backup and that you can take from "Ahsay software" It actually works.
