5/18    Is there any Windows backup program which (1) Let's you do a full
        backup, (2) Monitors all filesystem changes as they occur, then (3)
        Does an incremental backup on only changed files?  I don't want it to
        have to scan my entire notebook data-partition for changes; changed
        files should already be flagged for backup by the monitoring daemon.
        I don't want some hacky program that only runs file listings on
        specific directories every couple minutes and checks file sizes/dates;
        I want something which hooks into the Windows filesystem and is aware
        of all writes as they happen.  Basically, this strategy minimizes hard
        drive wear, and should be faster.  Thanks.
        \_ Um, RAID + tape?
           \_ Notebook hard drive.  Sorry, should have been clearer.
              \_ You've got to be kidding.  You want all this and on a laptop
                 too?  How about a 24" screen that can fit in your pocket while
                 you're at it.
                 \_ The "hard" step is hooking into the Windows filesystem.
                    Apparently Sysinternals Filemon does this, but it doesn't
                    do backup.
        \_ If you buy an external Maxtor drive with "One Touch", it comes with
           a license for Dantz Retrospective Backup. The drive+sw is <$200.
           \_ Does Restrospect hook into the Windows filesystem like I
              described?
        \_ Eh, screw it.  I lookd up Restrospect Professional, and it lets
           you make a "Disaster Recovery CD", which you can boot on a hosed
           system and restore all the files (rather than a complete re-install
           of the OS and all the apps).  This to me is worth more than the
           low-level file monitoring.  FYI, the one that comes with the
           external hard drives is "Retrospect Express".  I'll let motd know
           how it is in several weeks. -op
           \_ hell, you could just use ghost images then
              \_ I didn't fully explain how the feature is neat.  Okay, with
                 Ghost, you gotta do the whole freakin partition every time.
                 Wih Retrospect, you can do incremental backups to your
                 heart's content.  Each incremental backup is fast.  If
                 your disk gets hosed, then *after* it got hosed, you can
                 create the CD.  The disk gets restored to when you last
                 incremented.  Get it?
        \_ You want a program that hooks deeply into windows and keeps a db of
           files *as they change* and then copies them to something else?  I
           wouldn't want anything hooked that deeply into windows.  Note how
           intrusive the anti-virus programs are.  That's what you're talking
           about but worse.
           \_ That sounds like a slightly modified log-based fs.  Not that
              evil a thing, really.  I think there's a freebsd implementation
              floating around, yes? -- ilyas
              \_ Not evil per se as a concept but look at how the perform in
                 the real world.  I really wouldn't want anything hooking that
                 deeply into a windows system if it wasn't absolutely required.
           \_ If it came out, I'd buy it ... if Windows were still fast.
              Assuming you always back up the registry, all the monitoring
              process is doing is collecting a list of all
              new/changed/deleted/moved files since the last incremental
              backup.  The copy step occurs daily. -op
        \_ Put your data on a linux box and mount the samba share from windows.
           THen, use rsync and snapshot backups.

2/19    I program a lot by sshing to a Linux cluster.  So I'm used to using
        Xemacs to code.  This works fine from a Linux or Windows workstation,
        but sometimes I have to use a Mac.  On Mac, the meta is usually
        bound to option, but that often doesn't work over ssh for some reason.
