Operating system error 3(The system cannot find the path specified.)

Sooner or later, working with SQLBackupAndFTP you can get the following error message

DETAILED LOG:
27/11/2016 15:19:51 Creating backup of data_newlevel
27/11/2016 15:19:52 ERROR: Backup of data_newlevel failed: Cannot open backup device ‘C:\Windows\TEMP\data_newlevel200910271519.bak’. Operating system error 3(The system cannot find the path specified.).
BACKUP DATABASE is terminating abnormally.

The Solution will be the next:

Please grant LOCAL SYSTEM (or LOCAL SERVICE) account with write/read permissions for C:\Windows\TEMP… folder or specify different temporary folder

Also, please make sure that you have enough free space on your drive.

I get this ERROR now after upgrade:

I checked permissions in folders., nothing helps. HELP!

Hello,

Could you please make sure that the user from whom SQL Server runs has enough permissions to the following folder “DB_DUMPS”?

Hello I have the same issue, and I haven´t found the solution.

Someone have any idea?
