Just a quick note on backup - be sure you are clear on whether you want to recover some number of previous versions of a file or if you only want to recover the most recently changed version.
Rolling your own and syncing to a NAS or remote store is pretty easy if you only want the most recently changed version. If you want to recover prior versions, well, that's why people charge for backup and recovery, so if you want to try to roll your own here, be prepared. When I first started working at Mozy it really opened my eyes on how complex something that seems so simple can become. Also keep in mind that something like Drobo is only good for certain kinds of backup (e.g. recovering a file when a drive crashes). It won't do you any good if you are trying to recover old tax documents because the building caught on fire because your backup copy got hosed along with the original. That being said, I wonder if you couldn't accomplish this with a basic NAS and Git or SVN. A watcher script could automatically check in new versions of a file when they change. Of course, if you have 4 TB of data, just keeping track of the state of all the files is a non-trivial task in itself. -- Matt Ryan /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
