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

name, file type, and version number. For more

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

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.
