Restoring Data
The purpose of creating back up archives, of course, is to allow you to restore a
previous state of the CMS server instance after a hardware or software failure
corrupts your current state. The restore tool allows you to recover all or part of the
configuration that was backed up. For example, you can use the tool to restore just
the internal database of a CMS server instance.
A special case, automatic restore, allows you to completely restore the
configuration from the latest backup archive quickly and without interaction.
Before You Restore Data
Before you can restore from a backup archive, the archive you want to use has to be

the data.
If you moved the zip archive to another machine or removable medium, copy it
back to the local file system. If you encrypted the archive, decrypt it before you try
to restore the data.
You cannot restore data to a CMS instance that has not been configured. If you
re-installed CMS prior to attempting to restore data, you must configure the new
CMS instance. When you configure the new installation, keep the following points
in mind:

All services should be running on the same network ports as they were when
the backup archive was created. For example, the administration console port
is a random number by default; be sure to change the default to the same port
that your original installation used.
