Backup - is anything private stored?

Hello - I'm a new directory opus user.
Just curious, is it safe to store my directory opus backup file publicly? Is there anything private stored in the backup file? I didn't see the contents explicitly stated in the help. I ran strings on it and didn't see anything obvious.

There may be things in there you would not want to make public. (There definitely will be if you have any FTP passwords stored.)

You can rename the config file to .zip and look inside it if you wish, but I would not recommend sharing config files publically even after looking at them, just in case (and because full config backups usually aren't the best way to share parts of your config with other people, if that is what you want to do).
