“So what am I looking at?”
“Time machine for Windows.”
Rebit copies any and all changes made to your PC onto a backup drive, silently and automatically. If you ever need to go back to a previous version of a file you can use the normal windows explorer interface to inspect the disk as it was at any given date.
The system manages space automatically – if you make a change to a file every day for example then you’ll have lots of previous versions. As the drive gets low on space it removes the oldest copies automatically to make way for the newer ones.
Because it’s a complete system copy it can also recover a failed machine. You can boot up a machine using the recovery CD, pick a date and it will restore the PC to the exact state it was in at that time.
You can buy it packaged into various capacities of USB hard drive or as a separate software install if you already have spare storage. It can use any hard drive, built in or external as it’s backup store but not a network share (yet). Personally I quite like the idea of partnering it with one of these but that’s probably just because I’m looking for an excuse to buy a fireproof hard drive!
