Deleting Fix Backups
Every installed fix creates a backup, which allows you to uninstall that fix and revert to the previous fix version. You can use Update Manager to delete the backups of installed fixes to, for example, free up space on your machine.
Important:
Make sure to always use the latest version of Update Manager when deleting backups and always keep at least the latest backup. Preserving the latest backup allows you to return to the previous state when needed, for example, if the latest fix introduced a problem that is not yet fixed in a newer fix.
To delete fix backups:
1. Start the Update Manager application (command line or graphic interface).
2. Go to Delete backups.
3. Point to the product installation directory.
4. Specify how old are the fix backups you want to delete in days,weeks, or months. Specifying 0 means all fix backups are to be deleted.
All fixes older than the time you specified are displayed.
5. Make sure that the correct fix backups are displayed and confirm.
Deleting fix backups is not possible in the following situations:
When a fix depends on more than one product, you cannot delete its backup even if you try to delete the full backup.
You cannot delete the backups of support patches, which include diagnostic collectors, test patches, and hotfixes.
Update Manager informs you if there are any fixes that cannot be removed from the backup.
Warning:
Backups play a main role in the Fix Uninstallation process. To uninstall a fix, the previous version should be available in the backup. When the backup of the latest version is deleted you cannot uninstall the latest fix. Only delete fix backups when necessary.
