How to Resolve Error 70 Permission Denied When Backing Up Your Access Database

When it comes to managing databases, ensuring that you have a proper backup is crucial. However, many users face challenges when attempting to back up their backend databases, especially in a split database configuration using MS Access. One common error that arises during this process is Error 70 Permission Denied. This guide will dive into the causes of this error and provide a detailed solution to help you successfully back up your database.

The Problem: Understanding the Error 70 Permission Denied

If you have been trying to back up the backend of your split database located on a network drive, you might have encountered an error that states "Error 70 Permission Denied". This error generally indicates that your code does not have the necessary permissions to access the specified file or directory. This can happen for several reasons, including:

File permissions on the server: The account you're using to run the code might not have permission to access the files or folders.

File access when in use: If the backend database is currently being accessed or written to, that can also lead to permission issues.

Incorrect network path: Sometimes the mapped network drive may not point correctly to the desired file path due to network issues or incorrect configuration.

The Solution: Using FileSystemObject

One effective method to resolve the Error 70 is to use the FileSystemObject to handle file copying. This approach can help you bypass some of the permission issues associated with direct file operations in VBA. Below, I’ll break down the steps to implement this solution successfully.

Step 1: Utilize FileSystemObject

Instead of using the standard FileCopy method to copy your database, you will create an instance of the FileSystemObject. This allows for better error handling and permissions handling.

Here’s how to modify your existing function:

Step 2: Explanation of the Code

Create an instance of FileSystemObject: This allows us to work with files and folders in a more flexible manner.

Generate backup file name: The naming convention includes a date stamp, ensuring that backups are organized and distinguishable.

CopyFile method: This is the core of our operation. By using fso.CopyFile, you can effectively copy the backend database to your designated backup location without triggering the permission error.

Step 3: Testing Your Backup Function

After implementing the changes, it’s crucial to test the function by running it while accessing the frontend of your database. If everything is set up correctly, you should receive a success message indicating the database has been backed up.

Conclusion

The Error 70 Permission Denied can be a roadblock for many users trying to manage their MS Access databases. However, by adopting the FileSystemObject approach detailed above, you can effectively create a reliable backup process without encountering permission issues. Regular database backups are essential to safeguard your data, so ensure your backup function runs smoothly.

If you follow the steps provided in this guide, you should be able to automate your database backup process with confidence. For any further questions or issues, feel free to reach out in the comments!
