I wrote a few days ago about my experience with Mozy after my main system drive crashed. I have a small update: after finally getting whatever little they had back from Mozy, I was determined not to let this happen again and so I went through and re-configured the MozyHome client to backup every folder I thought I might ever need. That should have added a couple of gigs to over 60Gb already on Mozy (from *other* hard drives). Yes, you guessed it. Mozy did not recognize the fact that it already has 95% of my data on their servers and so it is uploading *everything* all over again. Not only is this a major waste of processing power and network resources, it also leaves me open and vulnerable until this backup completes!
Good idea, horrid implementation!
