I am unable to backup- "QuickBooks was unable to back up your company file. QuickBooks could not create a disk image."
It depends on the type of backup that you saved, magictouchcleans.
If you have Intuit Data Protect or QuickBooks Online Backup (OLBU), files are saved into the cloud. I would suggest reaching out to our Technical Support Team. They can take a closer look at the error that you're getting and help you find the backup copy.
Go the Help menu and select QuickBooks Desktop Help.
Click Contact Us.
Let them know that you're not able to open the online backup.
Click Continue, then select the available contact options.
