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!

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
