Your 5 Mbps is totally OK to set up cloud service for your most important data. The idea is to let the computers upload and sync when bandwidth is available. Move or copy the files to cloud folder and let it take as long as it takes. They will be all the time available on local computer and on cloud whenever the upload / sync is finished.
The situation changes if you with your 5 Mbps upload speed were using a NAS and you would need a larger file when away from home. At that point your home broadband upload limit becomes the download speed limit, the fastest you can get data from your NAS. Whereas 5 Mbps upload is totally enough to maintain a cloud service and keep copies of important files, documents and pictures alike, on cloud, it will be slow to get files from NAS when on the road and the need arises.
A cloud when used as it is intended to be used (talking now about private users) works in the background without you even noticing it. My Windows Phone is set to upload all the photos and videos I take and make automatically to OneDrive; of course I know that if I record a half an hour high resolution video, it will not be on cloud a second after I have pressed the stop and save buttons. But it will be there, tomorrow or next week.
