Managing the backup size of 4.0 installations
One common question that comes in is around how to manage the backup size in the 4.0 products. If you’ve installed a large number of updates, it can get unwieldy, and if you’re running out of room on the hard drive, this becomes an important question.
The good news is you can remove any update that’s been superseded by other installations – note however, that you cannot ever remove the base product installation. Updates will be superseded in each of the following situations:
Support Pack Lines: If you have 4.0, 4.0 SP1, 4.0 SP2, 4.0 FP3 (note this is also on the “Support Pack” level even though it’s a “Feature Pack”) and 4.0 SP4 instealled, you can remove SP1 through FP3 and not affect the system outside of the backup cache.
Patch Lines: If you have 4.0 SP4 installed, and then install Patch 1, Patch 2, and Patch3, both Patch 1 and Patch 2 have been superseded, and can safely be remove without affecting the system outside of the backup cache.
Note that, once multiple versions of minor releases become available, it would apply at that level as well.
To remove the packages, proceed through add/remove programs and remove the specific packages you’ve identified.
