Glossary of terms 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.
