SQL Backup and Restore to UNC

30 March,2013 by Jack Vamvas

A UNC (Universal Naming Convention)  mounts at any point on a logical drive. A UNC path is required if a DBA creates a  backup and restores from a UNC path.

I use UNC paths if disk space is limited on the server , and a storage administrator isn’t available to add another drive to the server with disk attached. I’ll create a  network share on another sever , create the SQL Server database backup , and  restore from UNC.

It can be much slower than straight to disk attached but it gets the job done.

--- Backup database to a UNC device . Note: \\server_name\drive_letter\path\file_name
 backup database My_DB to disk = '\\server1\H$\temp_backups\MY_DB.bak'

---Create a backup device . Useful if doing a UNC restore 
EXEC master.dbo.sp_addumpdevice  @devtype = N'disk', @logicalname = N'test', @physicalname = N'\\server1\temp_backups\MY_DB.bak'

-- restore from UNC
FROM DISK = '\\Server1\SomeShare\MyDatabase.bak'
