System+Restore+s+Disc+Space

System Restore needs a minimum of 200 Mb of available hard disc space. However, if more room is available it will automatically take up to 12% of the hard drive. Note that System Restore will yield some of it back to the system if it is needed, and it does purge points older than 90 days. However, this raises a question “ If the drive is almost full to capacity does it then prohibit creating Restore points ? “ Just a thought.
 * System Restore s Disc Space **

If you want to view how much hard disc space System Restore has potentially set aside follow these instructions:- Press the “Windows + Break “keys. This throws up the System Properties dialog window. Select System Restore tab Choose Your Hard disc fromAvailable Drivelist. Click Settings button. Displayed will be a number that represents the amount of space in Mb that System Restore is using to amass restore points.

If your Hard disc was a 80Gb 12% would amount to nearly 9Gb

If you feel that is to much you can reduce it by moving the slider to the left. Bare in mind that if not enough space is allocated no Restore Points will be created.
