trigerring mysqlbackup (from a Windows service) always fails , exit code=9 (IO operation failed).
It works fine when triggered from command line
I used procmon to trace this, mysqlbackup does not even attempt to create the files
My application uses system call (from procmon logs):
C:\Windows\system32\cmd.exe /c mysqlbackup --user=root --password=passwordhehe --port=3306 --with-timestamp --backup-dir=C:\BackUp_MSQL\NBMYSQL_5688_1655104226 backup
The same command from command line works fine
