Note: Before you apply a maintenance
release, you must stop all your SAS servers. It is recommended that
you back up all the files in your SAS installation and configuration
directories. Create backups of the installation and configuration
directories for SAS for each machine in your deployment, and use these
backups if you need to restore your previous SAS deployment. For more
information, see
“Best
Practices for Backing Up and Restoring Your System” in the
SAS Intelligence Platform: System Administration
Guide.
When you apply a maintenance release, SAS automatically
backs up any file in the SAS installation directory that will be modified
during this update. These backups are saved in the maintenance directory
for each product. The general format of this directory path is
SAS-installation-directory/product/release/maintenance. Here are
two examples of these backup directories:
-
For Base SAS 9.2:
SAS-installation-directory/SASFoundation/9.2/maintenance
-
For SAS Web Report Studio 4.2:
SAS-installation-directory/SASWebReportStudio/4.2/maintenance
If disk space is limited,
then after the maintenance release has been installed, you can use
the SAS Update File Cleanup Utility to remove the backups that SAS
created. This utility must be run under the user ID that was used
to install SAS. For more information about how to use this utility,
see the following resources:
