RollBack Rx Software - Professional 8.1 Free download

This is a good piece of software which will get you out of trouble when things you can't unpick have happened to your PC. BUT!! HorizonDatasys make a big thing of how little diskspace will be used by the rollback data. When I started using this I set the scheduled snapshots to once an hour so I'd never lose any real data. My hard drive soon shrank dramatically. Now I would recommend setting one snapshot per day and keep two weeks of snaphots before automatically deleting them. This still uses a lot of diskspace but it will take you back a fortnight in case you don't spot problems straight way. jon

DO NOT GET THIS PROGRAM. It will ruin your hard drive, and probably cause you to need to purge your whole system. The program saves a copy of all deleted files and prevents you from freeing up space. I loved it for the first week or so, until I found that I had 100MBs left of my 120GB hard drive. When I tried to free up more space by deleting files, I found that not only did the space not free up, but I actually LOST free space. I spent 3 full days trying to find the problem, when I finally decided to uninstall Rollback. After 3 hours of uninstalling it, I checked my hard drive, and I had 57GBs free. This program was a disaster to my computer. If I wasn't so savy with computers, my system would have been ruined, and I would have had to purge my whole system. Once again, DO NOT GET THIS!

@Adam Wutzel: simply use the defrag function in the program. seconds later you have all the space that the deleted files reserved before. :) so get this program. it's awesome!
