BackupIoRequest::ReportIoError: write failure on backup device '\networkpath\MYDB.BAK'. Operating system error 1(Incorrect function.).

using below script for DB back up:-

  • Sounds like a hardware failure. What makes you think it's software? – elixenide Apr 08 '16 at 02:42
  • But on Same Db server, Point in time DB back up completed. – Viraj Mehta Apr 08 '16 at 02:50
  • Just to update, I was managed to take full back up by connecting Management Studio using SA account. But i was getting above error when i was taking DB back up from my Windows Service Application. I think it is credentials issue. Not sure as of now. – Viraj Mehta Apr 08 '16 at 13:30
