I'll keep my opinions about the OneDrive app to myself. (I don't want to get blocked here again.)
I have advised posters to disable both syncing and Bitlocker as soon as they start to use their PC.
The OneDrive app will start syncing your folders as soon as Windows has finished installing, without any notification to you or explanation of what it's doing. This is very confusing to users and causes much anxiety. Here - in my opinion - is what you need to do as soon as you start to use your PC for the first time:
1- Open the OneDrive app's settings and turn off syncing.
2- Still in the OneDrive app's settings, empty the list of files and folders that the app syncs to OneDrive.
After you do this, all syncing will stop, and if syncing was to somehow recommence, there will be nothing for the app to sync. You are now back in control of your personal files and folders.
3- Change the default location of your personal folders (Desktop, Documents, Downloads, Music, Pictures, Videos) from the OneDrive folder ...
C:\Users\your user account\OneDrive\
... to your user profile ...
C:\Users\your user account\Desktop, Documents, etc.
It's even better to store your personal folders on on a separate partition: D:\Users\your user account\ ...
After you do this, the OneDrive folder should be empty.
4- Go to your OneDrive [ https://onedrive.live.com ] and review what the OneDrive app was able to do before you stopped it from syncing. If you see duplicate files, decide which copy you will keep (i.e., the copy in your OneDrive or the copy on your hard drive) and delete the other copy. If you see different versions of the same file, decide which version to keep.
Having done all the above, you are once again the master of your own data. You will decide what will live on your hard drive, what will live on your OneDrive, and what will be synced. Don't forget: You can always upload files to your OneDrive manually, by dragging and dropping, and you can always download your files manually from your OneDrive.
Now is the time to learn about how the OneDrive app works, and decide how you will use it, if you want to.
Backing up to the cloud, whether that's OneDrive or any other cloud storage service, is certainly better than not backing up at all. For someone who doesn't backup, or doesn't know how to backup, they could do much worse than letting the OneDrive app backup for them. However, backing up to the cloud has disadvantages, including:
* no versioning;
* can get very expensive;
* it's slow
* no way to verify a backup's integrity
* no imaging - just files and folders
Perhaps the single biggest disadvantage to making cloud backup your only backup is this: If you ever lose access to your cloud account - if it gets hacked or stolen or you forget your password - you have lost your backup, along with everything else you've stored in the cloud.
The cloud is better for archiving. A copy of my wedding video is stored in the cloud. Archiving means storing extra copies of important files that will rarely, if ever, change. And it should not be your only archive.
