let's take System Restore

System Restore does not cause any noticeable performance impact when monitoring your computer. The creation of a Restore point also is a very fast process and usually takes only a few seconds. Scheduled System Checkpoints (every 24 hours by default) are created only at system idle time to avoid interfering with a computer during use.

realy ... let's see
- system restore takes about 12% (at maximum) from your partition
if you have 50Gb partition it will eat 6Gb
- also it's known to be a "safe heaven" for viruses and malware(spyware and such); if you will delete/repair the infected file, at reboot it will be back
- and there's the issue of timing; it will start randomly, if you are in an on-line game ... you're dead
- it's suposed to protect your system in case of a disaster ... not quite
if key files are deleted of infected by a virus and the system will not boot in safe-mode, you'll have to intall it again
