Online backup failed on parameterization

[tmalone]

My online backup is OK for the DB tab.

On the Parameterization tab, I get an error: "Error while opening destination file"

I looked in log/WCCOActrl1 to see if it gave me the file or folder, I don't see any information.

How can I get this working?

FYI, firewalls are off, no virus protection, logged in as an administrator, not running as a service, changed permissions for backup folder and children

Which operating system and WinCC OA version are you using?
In October we have fixed a problem with the online backup. Possibly the issue in your project is solved if a new patch is installed.

sadly, we are on 3.15 P036

Maybe I can make the same patch if I know where the fix is?

We have opened a case for this issue. This error message might be a fall-through message as there is also a problem with the ASCII export of the database. I wonder if they are not related?

Additional information: If I delete ALL of the file in the backup folder, the online backup works without error. If it has backed up before to that folder, it will fail every time.

We solved our issue with this problem.

Windows creates a file called Thumbs.db in the project/pictures folder. This file is both hidden and a system file, when when the online backup tries to overwrite on the next save, it fails.

To remove this file:
Open a command window AS ADMINISTRATOR
C:/WinCC_OA_Proj/myProject/pictures> attrib -s -h Thumbs.db
C:/WinCC_OA_Proj/myProject/pictures> del Thumbs.db

To stop windows from creating this file:
Open the gpedit tool from the same command window
browse to: User Configuration->Administrative Templates->Windows Components->File Explorer
find the setting "Turn off caching of thumbnail pictures" and ENABLE it

thanks to Rick McMullan for helping me find this solution
