 - Check software version on the controller , go for https://software.cisco.com/download/home/286312601/type/280926587/release/8.10.190.0
                           check if that can help ,

What transfer method are you using (TFTP, FTP etc)?
Have tried using a different method?
Have you tried transferring to a different server?
Have you tried it yourself manually on the command line?

yes it has worked before. A maintenance window is planned and the WLC (in HA) will be reloaded. I will come back here if it resolves the issue. 

[gentjan]

It resolved the issue. Backups are running now as per schedule and no logs in controller related with invalid_file_handling=-1.
