    I am thinking about backup procedures for my server.

    I am currently using the following partitions on my Windows server: A)
    Main boot, OS and programs, B) Minimal OS install for restoring the OS
    if necessary, C) Data Partition for storing all shared data, D)
    Partition for storing drive images for mission critical work stations.

    Every day at midnight, the data is backed up to a file on a removable
    HDD identically configured (except that the backup files are stored on
    the D) partition). Additionally, a backup is made to a duty workstation
    left on Monday thru Thursday nights. The removable drives are exchanged
    at least once a week.

    Since Windows is less forgiving than Linux on changing hardware, a
    second computer identical to the server is used in location that is not
    mission-critical. If the server system fails, I swap the drive into the
    duplicate machine, or if the drive goes bad, I swap the removable drive
    with the internal boot drive. If possible, I transfer the current data
    from the old boot drive, or I restore the data from the duty
    workstation. Of course, if the worst nightmare occurs, loss of all
    computers due to a fire or total theft, I can use the removed drive to
    setup a new server quickly.

    The company for which I use this model starts having serious financial
    pains after as few as three hours of downtime depending on the time of
    month. (I just wish I had such protection on my own computer.)

    The restore process cannot restore an active operating system so I have
    to have the second install just in case. That was my thinking when
    setting it up, but if the internal drive and both removable drives all
    have a corrupt operating system, things are pretty bad. I set that up
    before I decided to use the removable drives.

    I don't know what "normal" backup procedures look like, I don't think I
    have seen any since about 1990.

    Anyone have any helpful suggestions?

    Buck
