Basic OneDrive Settings?

Hi all. Help please.

Having switched from OneDrive for Business to OneDrive with Windows 10 I'm struggling to understand settings.

I just want to use it for basic cloud backup. To hold working copies of material on the laptop, and back it up on the cloud - and don't want the thing to pull moves it's not asked to.

I've just had to delete (from the cloud, the cloud's recycle bin, and the PC) an out of date set of personal folders it dug up from somewhere (possibly the OneDrive for Business acct?) and dropped in the new OneDrive folder - and without asking commenced downloading them to the PC. (fed up with these automated functions...)

I've just dropped my personal folders in the WIndows OneDrive directory on the PC, it's (slowly) backing up and seems OK.

How do I get it to do the same with the Windows Documents, Downloads, Music, Pictures, Videos folders? I don't want it automatically extract material from eg the phone.

I've selected 'this PC only' settings for Desktop, Documents and Pictures, but am not sure what this delivers.

Even less so what choosing between 'sync all files' or 'sync these folders' options in 'choose folders' delivers...

It'd be nice to be able to access a document on the phone to read, edit or even start a new one, but only if it doesn't make life even more complicated/create more hostages to the great god MS...

Thanks

Thanks bro, that sounds like the way to keep the data on the cloud, and to drop selected files on to eg a mobile phone to permit work on them when offline.

Still wondering about these questions, I've written in explanations/what I think the answers may be in bold to make it easier to answer):

How do I get it (One Drive) to do the same (save the contents of these Windows folders to the cloud while retaining the originals on the PC) with the Windows Documents, Downloads, Music, Pictures, Videos folders? (and when this is done do these folders remain in their original locations in File Explorer, or are they brought inside the OneDrive ?)

I've selected 'this PC only' settings for Desktop, Documents and Pictures, but am not sure what this delivers. (does it mean that they get saved to the cloud, but that it's only possible to access these folders from the originating PC, and not from other devices?)

Even less so what choosing between 'sync all files' (presume this is an option to specify that all of the files/folders in the OneDrive web directory/on the cloud will be synced to/also saved on to the PC, but is this the correct meaning of 'all files' ? )

and 'sync these folders' (presume this is an option to specify that only the ticked/selected files/folders in the OneDrive web directory/the cloud will be synced to/also saved on to the PC, but is this the correct meaning? ) options in 'choose folders' delivers...

I write, and am concerned about reliability of backup - and have been a bit spooked at some of the automation and Microsoft diktat built into OneDrive.

Wondering in fact if it might not be safer to use an online backup service like Backblaze or Acronis that does what it's told instead?

OneDrive for Business (or was it something else that did it?) today automatically dumped a load of out of date folders into my newly set up OneDrive personal folder.

There's also reports of OneDrive automatically deleting music and video files stored in it. Reading between the lines this might have had to do with the legality of the downloads, but is this possibly a more general issue, and does it present a risk of data loss?

Thanks

I should add that the upload speed with OneDrive Personal seems glacially slow too. Typically below 100kbps with everything else off.

Notably slower than was OneDrive for Business...

The connection is variable, but OneDrive seems to nevertheless run a lot more more slowly that it permits most of the time. It's not throttled on any of the network settings, 'don't limit' and 'adjust automatically' seem to deliver about the same.

I'm guessing this is down to Microsoft, that there's not much to be done about it?
