Separating system files from the Application
Iguana enables you to keep your application data separate from your application. For example, you can store the Iguana server on one hard drive and put your configuration files and log data on a second hard drive. This separation ensures that your data will not be affected if something goes wrong with the hard drive on which your applications are running.
Separating Configuration and Log files
Iguana 4.0 and later versions also allow you to specify a separate directory for your log files. This means that you can store your application, your configuration files and your log files on separate hard drives or partitions. Separating your configuration files and log data makes it easier to test upgraded versions of Iguana.
See Changing the Log Directory for more information on how to specify the location of the log directory for your Iguana server.
