    Backup       A copy of a volume or selected files that are stored in
                 a save set for the purpose of recovering the files in
                 case of data loss.

    BACKUP       A utility (this program) that provides a screen-oriented
    Manager      user interface presenting a subset of commonly used
                 OpenVMS BACKUP Utility operations without the user having
                 to know about BACKUP command syntax and qualifiers.

                 For more information about the OpenVMS BACKUP Utility,
                 see the "OpenVMS System Management Utilities Reference
                 Manual" and the "OpenVMS System Manager's Manual".

    BACKUP       A listing of files that were processed that is either
    Output       displayed on the screen or stored in a file which you
                 can display or print.

    Baseline     A backup copy of a volume or selected files on which
    backup       incremental backups can be performed.

    Batch mode   Running a process in the background while allowing you
                 to continue to interact with the computer.

    bpi          Bits per inch; refers to the density of data storage for
                 a tape.

    Command      A way to run BACKUP Manager from the command line or in
    line         batch mode.
    interface

    Context-     Online help about BACKUP Manager user interface
    sensitive    features.  You can access context-sensitive help by
    help         pressing PF2 or the Help key (F15).

    Device       A physical disk or tape machine on which a volume
                 resides.  A device can be referenced by its physical
                 name (such as DUA0) or logical name (such as USER$DISK).

    Directory    An area on a volume where files are grouped.

    File name    A character string that identifies a file.  A file name
                 is segmented into parts for additional identification
                 purposes, such as device, directory, subdirectory, file
                 name, file type, and version number.  For more
                 information, see "File name format" in the "Concepts ..."
                 help topic.

    Fragmented   A disk on which files are stored internally in pieces
    disk         (though it appears contiguous to the user), causing
                 system performance degradation and multiple disk
                 searches for the pieces of the files.

    Fragmented   A disk on which a large percentage of files are stored
    disk         internally in noncontiguous pieces, resulting in file
                 system performance degradation when files are accessed.

    Incremental  Associated with a specific baseline backup, an incremental
    backup       backup is a copy of all files that are new or modified
                 since any previous backup.

    Label        A software name for a magnetic tape.  The label can have
                 up to six characters.

    List box     A box that pops up on the screen and that contains items
                 that you can choose, such as a device or a help topic.

    Listing      A file into which BACKUP output is written.
    file

    Logical      An alias or nickname used in place of the real name for
    name         an object (such as a device).  When a logical name is
                 encountered in a device or file specification, the
                 equivalence name string defined for the logical name is
                 substituted for the logical name string.  For example,
                 you might use a logical name USER$DISK when you want to
                 refer to a device known to the system as KRYTTR$DKA300.

    Multivolume  A save set that spans more than one tape volume.
    save set

    Qualifier    An option that modifies the behavior of a specified
                 operation.  Qualifier names are preceded by a slash (/)
                 and are used to modify a command on the command line
                 interface.

    Restore      Load files from a save set onto the specified disk
                 volume.

    Save         Copy files from a disk volume into a save set file and
                 store the save set on the specified volume.

                 In the context of templates, the Save menu item causes
                 the current screen values to be saved in the currently
                 selected template.  See also Template.

    Save set     A special file that contains file data and information
                 that is necessary to restore a volume or selected files.

    Snapshot     A snapshot copy of all specified files.  Does not
    backup       provide a baseline for incremental backup operations.

    Template     A record in which BACKUP Manager saves data entry and
                 operation attributes for later use.

    Volume       The logical storage of a disk or magnetic tape device.

    Wildcard     An asterisk (*) or percent sign (%) character used in a
                 file specification.  An asterisk represents any string
                 of zero or more characters, and percent sign represents
                 any single character.  For example, the name TEST%.*
                 matches any five character file name that begins with
                 TEST and has any file type such as TESTA.REPORT or
                 TEST3.DAT, but does not match TESTPLAN.TXT.
