Two big security flaws - version history and recycle bin - forced to use Google Drive
Recently I have experienced virus encoder attack.
Scenario: Virus encodes my mdb and accdb files in OneDrive folder on PC, files are uploaded to OneDrive.com, my files on OneDrive.com are also encoded. The result is I have lost all my data.
If version history was available for all file formats on OneDrive.com, healthy versions would still be on the OneDrive.com.
Scenario: Files in my OneDrive folder on my PC are accidentally deleted by me or deleted by virus (meaning they are not placed in the recycle bin on the PC). As I understand the size limit of recycle bin on OneDrive.com is 10%. What happens if the size of deleted files exceeds those 10%?
Are those files deleted permanently?
If deleted files are simple moved to the recycle bin without affecting used storage, there would be no permanently deleted files.

Had similar case with OneDrive for Business: Service Request ID: 616052491502224
OneDrive for Business didn't work as expected, meaning a file got encrypted/infected, we were supposed to be able to either restore its previous version from either version history or the online bin. And neither contained the unaffected versions in this case. The files were on Version 1.0 and the recycle bins of Level 1 and 2 contained no files at all. Had to request a manual restore from backup.
