OK, so I have 100 GB of free storage on OneDrive.
Have you tried it yet? Have you uploaded the stuff?
Last year (or the year before?) I tried a couple of cloud backups, but was too disappointed with the slow upload speeds. At no point did I find upload speeds fast enough to even call it a backup! What good is a backup, slowly becoming a backup because the upload speed is so slow, that several months will pass by, before the full amount of data is uploaded. No, that's not "a backup" at all. The first company I tried, gave me a speed so slow, that it would have taken me A YEAR to upload a TB! The second company was faster, but still much too slow for me.
But I have not tried our new "OneDrive"; please tell!
Your concerns were what kept me from trying free cloud backup services. The only reason I activated OneDrive is because they gave away 100 GB when they were pushing Bing. So by signing up I would have 125 GB total IIRC. For me the upload speed is not the issue because I use it to upload source code. If I tried to put a system backup image on it I don't think I could complete the upload in any reasonable time.
Source code and the small binaries that result from compiling AHK and AutoIt3 upload very quickly. I run the cloud uploader in the tray manually and copy the files over, then kill the OneDrive tray program when it completes.
I lost some source code when I left for Miami. So I figured since more than I will ever use is free I may as well at least have that backed up on the cloud. I can install a different version of Windows or even Linux. But I cannot fix bugs and recompile my programs if the source is missing. It is very frustrating.
The only way I could see using Cloud for backup in bulk would be if you have a business internet account with a lot of bandwidth. Or perhaps if you are a college professor and can use the WiFi 24/7 no charge. The fellow I took a class from for Computer Repair said he has something like 200 Mb/s download bandwidth at his disposal.
