When I've looked into this in the past, every provider has had issues with the new and archived content volume, and sometimes even the use of external rather than internal drives (!) that has made it unviable. I couldn't see from Mozy's site whether this was the case with them as well? If not and I can genuinely back up several hundred GBs of data (phone calls from ISP notwithstanding) and potentially add tens to low hundreds of GBs new data per month, from whatever drive source I choose, this sounds like what I want. Would this be the case from your experience?
