Recovering data with multiple backup strategies

    To illustrate a multiple backup strategy, assume you perform baseline
    backup operations on the USER$DISK volume on Sundays and incremental
    backup operations on that disk each night.  An event occurred on
    Wednesday that requires you to restore the volume to the most recent
    backup.  To restore the disk volume to its state at the time of the
    most recent incremental backup (Tuesday), perform the following
    steps:

    1.  Restore the most recent Sunday baseline backup.  Restoring the
        volume provides the base onto which you add the new and changed
        files since the baseline backup.

        a.  Choose "Restore Volume ..." from the File menu and choose
            the "Restore a volume save set (initializes the output disk)"
            from the list box.

        b.  Fill in the following field values:

            Input
             Save Set Device Name: USERS$DISK
             Save Set File Name  : USERS_BASE.BCK

            Output
             Device Name         : MUA0:

            Miscellaneous
             Listing File Name   : USERS$DISK.LIS

        c.  Choose any options you want from the Options menu.

        d.  Press PF4 or choose "Start Operation" from the File menu.

    2.  Restore the Tuesday incremental backup.  Restoring the
        incremental backup for Tuesday replaces files that were created
        or changed after the Monday incremental backup and before the
        Tuesday incremental backup.

        a.  Choose "Restore Volume ..." from the File menu and choose
            the "Restore an incremental save set"  from the list box.

        b.  Fill in the following field values:

            Input
             Save Set Device Name: USERS$DISK
             Save Set File Name  : USERS_INC.BCK

            Output
             Device Name         : MUA0:

            Miscellaneous
             Listing File Name   : USERS$DISK.LIS

        c.  Choose any options you want from the Options menu.

        d.  Press PF4 or choose "Start Operation" from the File menu.

    3.  Restore the Monday incremental backup.  Restoring the incremental
        backup for Monday replaces files that were created or changed
        after the Sunday baseline backup and before the Monday
        incremental backup.

        a.  Choose "Restore Volume ..." from the File menu and choose
            the "Restore an incremental save set" from the list box.

        b.  Fill in the following field values:

            Input
             Save Set Device Name: USERS$DISK
             Save Set File Name  : USERS_INC.BCK

            Output
             Device Name         : MUA0:

            Miscellaneous
             Listing File Name   : USERS$DISK.LIS

        c.  Choose any options you want from the Options menu.

        d.  Press PF4 or choose "Start Operation" from the File menu.

    BACKUP Manager restores the volume correctly regardless of the order
    in which incremental save sets are restored, but using the reverse
    chronological order is most efficient.  For example, assume that
    PROJECT.C has been updated and saved on Monday and Tuesday.  If you
    restore Tuesday's version of the PROJECT.C file first, then Monday's
    version of the PROJECT.C file does not have to be restored. If you
    restored Monday's version of the PROJECT.C file, then Tuesday's
    version of the file also must be restored, since it was updated and
    placed on the later incremental save set.
