I'm here to help you in backing up your data, dand18535.
If you're referring to the Intuit Data Protect, we can perform some troubleshooting steps to fix this issue. We can start by closing QuickBooks company file then perform the back up again since Intuit Data Protect will not be able to back up the file if it is open. If the same thing happens, let's verify IBuEngHost.exe to make sure that it's running as the System user.
Right-click on your taskbar, then select Start Task Manager.
You can also press Ctrl + Shift + Esc to access the Task Manager.
Locate the process IBuEngHost.exe and look at the user listed in the User Name column.
You can click Show processes from all users to see IbuEngHost.exe.
Verify QBIDPService.exe is started and reboot your system.
To check if QBIDPService.exe is running, we can open the Services Console from the Windows Run box (Windows + R) by typing in Services.msc and hitting Enter.
Check if the QBIDPService.exe status is Started (if it's not, you can restart your PC).
Lastly, we can check the drive file system to verify that it's NFTS. You can follow the steps below to check what file system is in use on the drive:
Open My Computer.
Right-click on the C drive, then select Properties.
If you're referring to the local back up, generally this happens the problem is that the backup location/directory is no longer accessible. To fix this, we can unmount the drive then remount it. We also need to make sure that the storage device has enough space. Sometimes, rebooting the computer is necessary.
Let me know how it goes in the comment section, as I want to make sure that you'll be able to create a backup. I also encourage you to post the error or a screenshot of it (if you receive one).
I have had QB for Mac since 2016 and about 6 months ago the back up stopped working. It would just sit on my screen and not finish backing up no matter where I tried to put the files. I just recently upgraded to QB 2020 and the same thing is happening and I have lost all the work from 1/6/20 until 3/30/20. No matter where I put the back up to save whether it is the iCloud or my HD. How can this be fixed.
Let’s perform some troubleshooting steps to back up your company file in your software, DAB Consulting.
QuickBooks for Mac has a built-in disk utility that your software uses to create a DMG (image) file when backing up your data. This unexpected behavior usually happens when the backup location is no longer accessible.
Let's verify where you're company file is located. Then, try rebooting your computer can also help resolve this problem.
If the steps will not resolve the problem, let's run the Verify/Rebuild Utility Tools to repair any damaged components within the company file. Just check out this article for the steps and details: Resolve data damage on your company file.
Once the rebuild completes, verify the data again to ensure there aren’t any other issues in the company file.
If you’re still unable to back up the file, I'd suggest contacting our QuickBooks for Mac Technical Support Team for further assistance. They'll pull up your account in a secure environment and investigate what's causing the missing data you have from 1/6/20 until 3/30/20.
