10BACKUP is a VAX program to read DECsystem-10 BACKUP format
10BACKUP has two primary functions; to get directories of, and to
selectively restore files from tapes written by BACKUP on a
DECsystem-10. Because INTERCHANGE mode is used to read the tape, any
UFD and disk name information on the tape is ignored.
Because of differences between the DEC-10 and the VAX this program
is intended mainly for restoring ASCII files. Limited facilities for
restoring binary information are available through the SIXBIT command.
The EXIT command is used to exit from the program.
The Tape command identifies the tape device to be used by the program.
The tape is assumed to be a DECsystem-10 BACKUP format tape and to be
Format: TAPE device
The SSNAME command is used to select a particular save-set name. All
other save-sets on the tape are ignored. To use the default mode of
selecting all save-sets, no save-set name should be specified.
Format: SSNAME save-set
The DIR command is used to get a directory of the tape. This command
shows the selected files, their sizes, and creation dates. The only
wildcarding allowed in the optional file name list is the * character,
which may be used in place of an entire file-name or an entire

The RESTORE command is used to restore the selected files from the
tape. The files are written to the current default area using the same
names as they have on the tape. A list of file names may be specified
in the RESTORE command to select particular files to be restored. The
wildcard character * may be used in place of an entire file-name or an

The FILE command is an alternative to the TAPE command, to be used when
the DECsystem-10 BACKUP tape has been copied into a VMS file. The FILE
command cause all tape information to be read from the specified file.
The file must have the format where each tape block is stored as a file
record, with any tape marks being represented by zero length records.
At La Trobe a suitable format file can be created from the source tape
using the COPYTAPE program. On a TU80 this command is useful for
performance reasons, as the COPYTAPE program keeps the drive streaming,
where as 10BACKUP may not.
Format: FILE file-name
The REWIND command rewinds the tape so that it may be reprocessed. If
the tape information is in a file the file is positioned at its
The SKIP command is used to skip over one or more save-sets. The
command parameter describes how many save-sets to skip.
Format: SKIP n
The SIXBIT command causes the RESTORE command write out files in SIXBIT
mode. SIXBIT takes an integer parameter to say how big the output
records should be in characters. If the parameter is zero then the
restored files are written in the default ASCII format. SIXBIT could
be used when the required files are not in ASCII and a user program
could be written to convert the data to the required format.
