A Microsoft file hosting and synchronization service.
I think part of the problem is confusion over what onedrive does. When I say confusion mean user, but partly microsoft fault and also companies that install onedrive for employees without having policy ("we got rid of our backup software - just use onedrive").
All I need is nightly backup. Our company used to have backup service, it was straight-forward and effective. This worked so well they decided to get rid of it.
Onedrive is not really backup . . . it is some kind of sync-ing w/ cloud (if you save over a file w/ onedrive one, it gets synced). It is not clear to me exactly what it does in all situations, and it creates confusing messages sometimes. The worst problem is that it conflicts with FEA code, so I can't leave it one. So I have to manually turn it on and off.
I'm not saying that onedrive does not have a role - but I don't see it as good backup package.
