Wondershare Time Shuttle

This is a backup program with a difference (or two), but as yet not well known, and with no user forum. If there are any other users here there are a couple of aspects which I'm unclear about -

- The Help says not to run defrag programs after installation, but both Vista and Win 7 defrag automatically. So far this doesn't seem to have caused any problem for me, but may do so in future possibly?

- The Help also says to uninstall the program before restoring an image, which seems to imply that however the program stores its snapshots they are not included in any images created by the likes of Acronis. This might be consistent with the claim that snapshots do not use any disk space, which I have yet to disprove, improbable as it sounds.

The program's ability to restore the system to an earlier state in seconds is nothing less than mind boggling and I look forward to getting feedback from other testers. A free trial is available at
