    Backup + update logging?


    As one of the dying breed of Main Frame dinosaurs I sometimes wonder why PC backup software, regardless of incremental or differential methods, relies up a full scan of the media to determine what has changed.
    Is there no package that utilises periodic backup with logging to provide point in time recovery?

    Hi there

    (BTW you can run various versions of the IBM mainframe OS's from MVS to current MVS/ESA (you need a license for that one BTW) including TSO (remember that) -- the old MVS is in the free domain now -- by using the Hercules emulator on a PC !!! works quite well !!!)


    The answer you need is probably not in Windows -- but how about rsync in Linux !!! does what you want --of course there could be 2 schools of thought on this

    1) you obviously can make the backup run a zillion times faster by analyzing the directories and using data from the directory to see what's changed -- this of course depends on the amount of sensible logging - journaling in the file system.

    2) the other way is to compare the data on physical sectors irrespective of the file system

    or could be a combination of 1 and 2.

    However the backup is actually done the important things are that you take them regularly and check that they do work.

    Imaging and cloning disks is a far easier thing to do rather than backing up and archiving data though which is probably why the windows free backup solutions only usually offer those options rather than sophisticated data backup and archive.

    I use a combination of 2 systems --I backup windows system (image) and then backup data to NAS via attach Windows drives to NAS and run the rsync command. Using CRONTAB as well can run these jobs at specific intervals / dates etc etc.

    Has a nice GUI version as well GRSYNC -- there's zillions of options too.

    Thanks Jimbo.

    Just a wild guess, but is your given name James?
    If so, snap! From one Jimbo to another.

    My speciality (for about 40 years) was IMS, so if you know that beast you'll see where I'm coming from.
