Allocating space for system restore in windows XP home edition

By winch1020 ·
If using multiple partitions and for example
'put the windows operating system on a small 2 gig to 3 gig partition for quick hard drive scanning of the basic operating system; one inconvenience
is that windows uses a slider that allows for a maximun of 12 percent of the total size of the partition that can be set aside for creating restore points altho for some other small partitions it allows up to 20 percent.Why can't
windows allow the option of using a separte partition just for creating restore points and the user could have as many gigs available for creating system restore points as required without having to make a partition 10 times larger than necessary in or order to get a half
decent amount of allocated space for that particular partition at a rate of 12 percent maximun of the total space of that particular partion or any other partitions that the user has created for storing othe programs etc.

You're not making any sense ...

What is your basis for the idea of "quick hard drive scanning" by having Windows in a 2GB to 3GB partition? Scanning by what?

If you install Windows in a 3GB partition it will run out of room as soon as you install a decent sized Windows application. Where are you going to put the Pagefile, or the Hibernation file, or ANY of the Temp files?

Any system operation that requires the HDD read head to navigate to another partition, inevitably slows the HDD read-times down, which will slow Windows down too.

Whenever you set a Program's install path to a different partition, that Program still makes entries inside the Windows partition for various system components like Registry entries, common files entries, user info files. Therefore Windows MUST have room to expand, as over time it will require more space.

What is the total size of your hard drive that would make you consider squashing Windows as much as you do?

I do not understand it either.. The question is why do this?

To me the guy is going to make more problems for the system then trying to make it run faster. If in the end he gets it running that way, he will be back asking the three W's (www) "what went wrong".

Please post back if you have any more problems or questions.

You determine the necessary space for Restore

by nepenthe0 In reply to Allocating space for sys ...

How much space you allocate for System Restore depends upon your level of confidence and whether or not you have alternative backup.

System Restore will not always rescue you. Without an image of your operating system and settings, the day will certainly come when you attempt a Restore procedure and Windows informs you that Restore cannot restore.

Since Restore files do not load into memory, their bulk does not affect performance. However, their bulk will affect backup time to removable media or to an external hard drive. With storage so inexpensive these days, the size for your Restore file should be simply a matter of personal preference.

Windows XP normally creates a Restore point every 24 hours of machine operation. You can modify this if you wish, by a simple Registry edit:


Open subkey RPGlobalInterval

The default value is 24 hrs (86,400 seconds).

You can change the default value to 8 hrs (28800 seconds) if you wish.

I cannot stress strongly enough that you should not place 100% confidence in System Restore. It will fail when you need it most. The correct solution is imaging software such as Norton Ghost:


and an external hard drive to archive your image folders.
