VMS BACKUP Saveset Internal Structure As Seen By An RT-11/TSX-Plus User Abstract This package represents my efforts to date to provide the RT-11/TSX-Plus user community with utilities to read selected files from a VMS backup magnetic tape. I have not been able to reverse engineer all of the saveset structure to be able to accomplish this in as complete a manner as I would like. Reading the tape is trivial as is evidenced by the .DAT files included with this package. This package consists of one data file and five logical device files. They are: File Name Length Description SAVSET.DAT 992 Saveset from the VMS backup tape. CVRCDS.DSK 101 Program to convert VMS ASCII records to RT-11 ASCII records (17 files). EXTFLS.DSK 170 Program to extract selected files from a selected saveset (26 files). SVSTDR.DSK 58 Program to make a directory of a selected saveset (21 files). TAPEDR.DSK 169 Program to make a tape directory (21 files). VMSBCK.DSK 65 Miscellaneous data and text files (7 files). The files contained within CVRCDS.DSK are: File Name Length Description *.COM 7 Command files to build CVRCDS.SAV (4 files). CVRCDS.DAT 7 COMMON and variables declarations. CVRCDS.FOR 8 Top module for CVRCDS.SAV, includes user instructions. *.FOR 37 Supporting modules for CVRCDS.SAV (16 files). CVRCDS.SAV 34 Executable. PAGE 2 The files contained within EXTFLS.DSK are; File Name Length Description *.COM 8 Command files to build EXTFLS.SAV (4 files). EXTFLS.DAT 7 COMMON and variables declarations. EXTFLS.FOR 10 Top module for EXTFLS.SAV, includes user instructions. *.FOR 62 Supporting modules for EXTFLS.FOR (18 files). MTLIB.OBJ 4 Special version for this package. EXTFLS.SAV 71 Executable. The files contained within SVSTDR.DSK are: File Name Length Description SVSTDR.COM 4 Command file to build SVSTDR.SAV. SVSTDR.DAT 7 COMMON and variables declarations. SVSTDR.FOR 9 Top module for SVSTDR.SAV, includes user instructions. *.FOR 56 Supporting modules for SVSTDR.FOR (16 files). MTLIB.OBJ 4 Special version for this package. SVSTDR.SAV 70 Executable. The files contained within TAPEDR.DSK are: File Name Length Description TAPEDR.COM 4 Command file to build TAPEDR.SAV. TAPEDR.DAT 8 COMMON and variables declarations. TAPEDR.FOR 9 Top module for TAPEDR.SAV, includes user instructions. *.FOR 59 Supporting modules for TAPEDR.FOR (16 files). MTLIB.OBJ 4 Special version for this system. TAPEDR.SAV 77 Executable. PAGE 3 The files contained within VMSBCK.DSK are: File Name Length Description EOF1.DAT 1 EOF1 record from the VMS backup tape. EOF2.DAT 1 EOF2 record from the VMS backup tape. HDR1.DAT 1 HDR1 record from the VMS backup tape. HDR2.DAT 1 HDR2 record from the VMS backup tape. VOL1.DAT 1 VOL1 record from the VMS backup tape. ABSTRA.DOC 12 This file.
