I need to check when a certain parameter was changed in my ZD1200 (fw 9.13.3). I have several backups but they are not text so I cannot know which is the first that includes the change. Is there something like a log of configuration changes I can check?
Best Practices say to 'sometimes' take a ZD configuration backup, and 'always' take one before an upgrade. *And you need to add some digits to your filenames, to identify what version and date on your backup files!
If you have previous backups, you need to be running the version they were saved on, but will have to look at the Admin screens to determine any changes... there isn't a Text output of configs that can be compared offline I'm afraid.
