Hi, I'm trying to get an automated solution going. What I need is some device/drive that copies any and all changes made to your PC onto a backup drive automatically. I don't want it to overwrite anything, I need previous versions of the same file to be available. If I even need to go back to a previous version of a file I deleted (damn I hate when I do that!!) I would like to use windows directory or maybe my browser to go to the device/drive and fine the file. So, if I make a change to a file I would have all the previous versions if I needed it. I would want it to be a complete system copy – it would in effect take a complete image of my HDD so I can use it to restore the system to the last working image – I really need this, since I keep getting a viruses from blogs and forums. I mean, it would be like a normal usb portable drive, maybe 1TB – but it would do all this stuff automatically, and when I need a file or a fresh re-imaging I would go into a simple Windows like interface and do it. I think 1 TB would be enough, and I don’t know if there is any software that would delete the older files if it needs more space for the newer files. Does such a device/drive exist?
