The "back up and validate" function only downloads all the data if you're using a storage location that doesn't provide checksums (SFTP or NAS/folder). So, it shouldn't be downloading very much if you're using it with OneDrive. Please email [e-mail] so we can follow up on this. Thanks.

I don't have automatic updates enabled and it has been a while since I manually updated. I just updated and the "back up and validate" menu item is no longer there for my OneDrive backup. It is still there for my backup to a local removable drive.

I see from this Reddit thread [1] that it was removed for storage locations that don't need it a few months ago, saying

> Back Up and Validate is a waste of time and money for any storage location that provides checksums. That's why we removed it. It only causes pain and cost.

My last "back up and validate" to OneDrive was a couple months before you removed it, so it looks like I was just hitting the "waste of time and money" case that prompted its removal.

From the Reddit thread, it looks like the way to do a check that everything is OK on both ends when using a storage provider that provides checksums is to clear the cache and to modify the backup plan (just editing it and saving is sufficient), and then do a backup. The cleared cache makes it get the checksums for everything in the backup and the modified backup plan makes it rescan everything locally. Is that correct?

There's no need to edit the backup plan. As I wrote in the reddit thread, clear the cache and do a backup. Sorry it's not more clear.
