What are your filesizes? And what sort of transfer speeds are you getting with your current internet connection?
Pushing a 1GB assembly/rendering to the cloud on a 3MB/sec upload connection could take hours…
That’s the primary reason we have a massive server with a back up server running daily backups instead of going to cloud based. Plus, we didn’t want the downtime of pulling everything off the cloud for a quick change, then putting it back on. WIth massive assemblies, unless you’re using something like Pack&Go or even PDM Works, it might get messy.
