Possible Causes & Solution of Operating System Error 3
Cause 1: Lack of Permissions
The primary reason behind the occurrence of this error is that account is specified for SQL Server does not have the write permission on the particular folder. However, lack of permissions can also be one of the root causes of the occurrence of this error.
- To solve the issue first, check the permissions that a particular is having. To do the same, right-click the folder and go to the Properties >> Security tab. After that, confirm the SQL Server service account has both permissions i.e. read & write for that particular folder.
- However, it can be possible that the particular account is part of some group that has permission but is not granted directly to the account. In this case, grant full permission to the account. Because there is no damage in adding the account directly with the required permissions.
Note: To confirm the lack of permissions is the root cause, grant full permission to everyone and then, test the backup process.
Cause 2: Unable to Locate Mapped Drive
Another possible cause of this error message is that SQL Server is not able to locate the mapped drive, which is specified for the “temporary directory for maintaining backup files”. Otherwise, the reason is disk issue with the specified temporary directory.
While setting up “temporary directory for storing backup files” to a network drive, it is always suggested to use fully qualified UNC path (e.g. \\remote_server\share_DB) rather than the mapped drive (e.g. Z:\ where Z is the mapped drive letter) for the temporary directory.
Or to check disk error, go to Control Panel >> Administrative Tools >> Event Viewer on the corresponding system. If there is a disk error, execute a checkdisk on that respective partition by executing the command chkdsk /f in the command prompt.
Cause 3: Why Cannot Open Backup Device Operating System Error 3
Trust Issues Between the Domains: The lack of trust between the domains can also be one of the cause if the SQL Server installation and the database backup folder resides on separate computers or active directory domains. It can occur even if the SQL Server account has the full permissions.
In order to resolve this issue, make sure that domain-to-domain trust is maintained properly, and also set up SQL Server service account using pass-through authentication between the two domains.
