Sql-server – SQL Server 2008 Database Restore Error – Cannot open backup device 15105

backupsql serversql-server-2008

I am trying to restore from a backup and getting the following error

Msg 3201, Level 16, State 2, Line 1
Cannot open backup device 'Z:\FULL_BACKUP.bak'. Operating system error 3(failed to retrieve text for this error. Reason: 15105).
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.

The code that I used in SQL Server is as follows (I also tried using the dialog screens and got the same result)

RESTORE DATABASE DEX
FROM DISK = 'Z:\FULL_BACKUP.bak'
WITH MOVE 'Decri' TO 'E:\Test\DEX.mdf',
MOVE 'Decri_log' TO 'E:\Test\DEX.LDF'

It may be worth noting that the "FULL_BACKUP" is created by the same SQL server, without any issues (so I assume that the server has permissions).

Drive Z is a network path, for which there is 'full access' to all domain users.

The full backup is 200Gb

Drive E (local) has 500Gb free space

Any help would be appreciated.

OS Error code 3 is ERROR_PATH_NOT_FOUND: The system cannot find the path specified. With a path starting with Z: my pshyhic powers tell me it is a mapped drive. Drive mapping is session scoped and I'm convinced your service session does not see Z:. Mapping a drive to be seen by a service is, for all practical purposes, impossible.

Use a valid path. Use UNC names like \\server\share. Consider the security implication of impersonation and delegation when accessing remote shares.

Try this:

CREATE DATABASE foo;
GO
CREATE DATABASE bar;
GO
BACKUP DATABASE foo TO DISK = 'c:\temp\x.bak';
BACKUP DATABASE bar TO DISK = 'c:\temp\x.bak';
GO
RESTORE HEADERONLY FROM DISK = 'c:\temp\x.bak';

Relevant columns for this scenario:

Position  DatabaseName
--------  ------------
1         foo
2         bar

To restore foo, whether it exists or not:

RESTORE DATABASE foo FROM DISK = 'c:\temp\x.bak'
  WITH FILE = 1, REPLACE;

To restore bar, whether it exists or not:

RESTORE DATABASE bar FROM DISK = 'c:\temp\x.bak'
  WITH FILE = 2, REPLACE;

If you don't specify WITH FILE, you will get a slew of errors, depending on whether the database in Position = 1 already exists.

The lessons here:

do not use common and generic names for backup files - name them for the database they represent and keep them separate.
use WITH INIT if you expect a backup file to only ever contain one copy of a backup.
understand what is in your backup by first running RESTORE HEADERONLY and/or RESTORE FILELISTONLY.

If you show us those two columns from the output of RESTORE HEADERONLY and what database you are actually trying to restore, we can provide you with a specific command that should work.

Your syntax is wrong for adding a backup device.

When you create a backup device in SQL Server you are actually creating the "bak" file as a media set.

Along with the suggestion from Bob that you should be using the full UNC path, your syntax should be changed to something like this:

IF  EXISTS (SELECT name FROM master.dbo.sysdevices WHERE name = N'NAS_YEDEK_DB')
EXEC master.dbo.sp_dropdevice @logicalname = N'NAS_YEDEK_DB'
GO

EXEC master.dbo.sp_addumpdevice  @devtype = N'disk', @logicalname = N'NAS_YEDEK_DB', @physicalname = N'\\10.1.1.x\yedek_db\YEDEK_DB_backup.bak'
GO
