SAS 9.3 Guide to Software Updates

40 Chapter 7 / Using Backups and Restoring Customizations
Some of this increase in disk space is temporary because you can remove some files
after applying a maintenance release. For more information, see “Creating and
Removing Backup Files” on page 40.
Creating and Removing Backup Files
CAUTION! You cannot combine SAS 9.2 and SAS 9.3 orders in the same
software depot. When you initially install SAS 9.3, you are required to create a new
software depot.
Note: Before you update an existing SAS 9.3 installation, you must stop all 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 SAS Content” in Chapter 11 of 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:
n For Base SAS 9.3: SAS-installation-directory\SASFoundation
\9.3\maintenance
Examples of this path in Windows environment include C:\Program Files
\SASHome\x86\SASFoundation\9.3\maintenance and C:\Program Files
\SASHome\SASFoundation\9.3\maintenance
n For SAS Web Report Studio 4.3: SAS-installation-directory
\SASWebReportStudio\4.3\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
