Preparing your system

Corrective service is different from the installation of a new function or preventive service.

It usually affects a limited area of the system.
It is usually done because a severe problem is affecting the system.
There is a need for an immediate fix.
The fix usually takes little time to install.

Thus, there is usually no need or time to prepare the system by backing up packs, compressing libraries, and so on. If possible, it is a good idea to have a backup system available in case a problem does occur.
