Do a Google on Docushield. Some friends of mine have designed this backup system for lawyers and doctors for HIPAA, etc., which requires better management of patient data. I've told them they are missing their market - I'm the market they should be after! A couple of hard drive crashes and I'm a believer. They've been letting me connect to their corporate Docushield, where I save my files to CVS. It's then mirrored to another Docushield off-site. CVS is mirrored on my local machine as well so I don't have to be connected to get my data. The Docushield system has a patented backup system which will allow it to be unplugged in the middle of a data write, then picks where it left off when power is reconnected. It has a local LAN, a secure Internet connection for the mirroring, and uses an electronic key carried on the owner's key ring to completely lock the system. The data is encrypted on one hard drive, then periodically encrypted and compressed onto a second drive. It's smaller than most notebooks and uses a web browser as the user interface. Sweet...

I think there are a number of different objectives for what often is called "backup" which are to be solved efficiently by different tools, usually. 1- quick and complete system restore (often to a different disk or partition) in case of disk failure (RAID is probably the most user-friendly for this one) 2- quick and complete system restore in case of a bigger thing like a fire in the office (needs off-site storage of the above, therefore some media -- which could be one disk of a RAID array that gets exchanged once a day) 3- quick and complete system restore in case of user or system error (usually to the same disk or partition, just going back in time a bit -- RAID wouldn't help here, this needs an actual backup and therefore a method for rotating the media, or unlimited budget) 4- archiving of files that are not needed frequently (doesn't usually have to be quick, as it supposedly is not a frequent thing, and can even be spread over different media -- which shouldn't be the case with the methods above --, as long as they are properly catalogued) 5- version control of files with which people work (that's the cvs thing -- very useful, but not quite a possibility for the whole system -- and the version control repository itself needs backup through the former methods) Having all that integrated in a file system doesn't seem to be impossible with today's hardware capabilities and prices. From what the mainframe people say, something like that has already been done. -- http://www.piclist.com hint: The PICList is archived three different ways.
