Hi Christopher8,
Thanks for joining in on the thread. I'll help you look into the cause and resolve the error you received when backing up your company file.
There are a few reasons why you received the aforementioned error when backing up your company file. It could be because the backup folder is inaccessible, there is damaged data on your file, your storage drive doesn't have enough space, or your firewall or antivirus program is blocking the process. We'll take some steps based on these factors to fix the issue.
Step 1: Make sure that the destination folder or location path is correct.
To do this, you can create a backup like you did one for the first time, where you select a destination folder. Some users forget that they selected an external drive for backups. As a result, they receive the same error when QuickBooks creates a backup when they close their file, assuming the drive is disconnected.
- Go to the File menu and select Back Up.
- Choose a folder to store your backup.
- Select Start Backup.
Step 2: Fix the data issue by running the Verify and Rebuild data utilities.
You can skip these processes since you're done with them, but I'm just including them for the benefit of other uses in this thread. These built-in utilities will check for damage data, like broken transaction links, and fix them.
Step 3: Check the available space of your storage drive.
If you're using an external storage or a drive partition, make sure it still has at least 1 GB of available space or more, depending on the size of your company file.
Step 4: Disable your firewall or antivirus program for a moment.
You can skip step this since you were able to back up your other files. However, for other users, they can do this while their computers are disconnected or not accessing anything on the internet while their firewall or antivirus program is turned off temporarily. If the said security features or programs are the cause of the issue, they can change their settings to allow QuickBooks activities.
