Hi there, Paul. I'm here to ensure you'll able to create a backup copy of your company file to an external drive in QuickBooks Desktop (QBDT).
To start, may I know if you receive an error when creating a backup copy of your company file? If none, let's first verify that you can see and locate the external drive on your computer.
If confirmed, you can also create a backup copy of the company file and saved it to a local folder in your computer, and copy it to the external drive. Here's how:
- In your QBDT company, go to the File menu and select Switch to Single-user Mode.
- After that, go back to the File menu again and hover over Back up Company. Then, select Create Local Backup.
- In the window, click Local Backup and then Next.
- From there, select Browse and select a local folder you want to save your backup company file.
- This runs a test to make sure your backup file is in good shape before you save.
- Once done, select OK.
- Click Save it now and Next. You'll get a confirmation message once done.
- After that, move or copy the backup data to your external drive.
On the other hand, you can also use a different external drive when creating a backup. Might be that the current one you're using caused the issue.
Additionally, for a company backup that is located on an external device, you have to move it first to your local hard drive before restoring it.
I also added this helpful resource that you can use as a guide in case you need your accountant to review your books while working: Use the Accountant's Copy.
I'm always here ready to lend a hand if you have other concerns about creating backups of your company file. Have a great day ahead, and stay safe.
