Your OneDrive is usually located at C:\Users\<username>\OneDrive. Create a folder for your backups on your OneDrive, then point OST and QB to save your backups there by going to the Tools menu, selecting Options, then clicking the Folders tab. You will see a line on that tab for your backup file location. Saving your databases in a Cloud location like OneDrive is just fine, but we never recommend accessing and working in databases on Cloud drives. Instead, to restore your database from a backup, go to your OneDrive folder and copy the backup file and then paste it into your main hard drive before you open it in OST or QB.

😂😂😂 good one!
