  • That error might appear when you try to backup SQL Server database to a network drive.
  • Therefore, this problem message usually occurs as a result of mistaken permissions to the network drive.
  • Also, this issue can occur when there’s no directory with Log or there is not enough space on your drive.

How to Fix Cannot Open Backup Device Operating System Error 5(Access is Denied)

If you get that error using SQLBackupAndFTP try to specify a temporary folder for the backup job like C:\Temp and check if it fixes the issue.

If it still throws the same error, or you get this issue using SQL Server Management Studio please check NTFS permissions for the folder you have specified and make sure if all users of your system have all permissions to it.

To avoid the issues related to NTFS permissions we recommend you don’t use a folder in your profile folder like C:\Users\….

Another but the more rare reason for which this issue may arise is that a backup file with the same name already exists in the folder and it’s Read-Only. To fix it just right-click on it then choose “Properties”, uncheck Read-Only and press “Apply” to save all new settings.

If “Read-Only” is unchecked but you still have this issue go to the “Security” and give all necessary permission to the user.

After all necessary configurations are done you will be able to perform SQL Server database backup successfully.
