NAME
vmsbackup - read a VMS backup tape SYNOPSIS
vmsbackup -{tx}[cdenvw][s setnumber][f tapefile] [ name ... ] DESCRIPTION
vmsbackup reads a VMS generated backup tape, converting the files to Unix format and writing the files to disc. The default operation of the program is to go through an entire tape, extracting every file and writing it to disc. This may be modified by the following options. c Use complete filenames, including the version number. A colon and the octal version number will be appended to all filenames. A colon, rather than a semicolon, is used since the Unix Shell uses the semicolon as the line separator. Using a colon prevents the user from having to escape the semicolon when referencing the filename. This option is useful only when multiple versions of the same file are on a single tape or when a file of the same name already exists in the destination directory. The default is to ignore version numbers. d use the directory structure from VMS, the default value is off. e Process all filename extensions. Since this program is mainly intended to move source code and possibly data from a DEC system to a Unix system, the default is to ignore all files whose filename extension specifies system dependent data. The file types which will be ignored, unless the e option is specified, are exe VMS executable file lib VMS object library file obj RSX object file odl RSX overlay description file olb RSX object library file pmd RSX post mortem dump file stb RSX task symbol table file sys RSX bootable system file tsk RSX executable task file f Use the next argument in the command line as the tape device to be used, rather than the default. If vmsbackup is compiled with the remote tape option and the file name has the form system[.user]:/dev/??? vmsbackup will use the tape drive /dev/??? on the remote system system, via rsh(1), and rmt(8). The optional user portion of the pathname specifies the login name to use on the remote system. If it is not supplied, the current user's login name will be used. In all the cases, the user must have the appropriate permissions on the remote machine, in order to use this facility. The default is /dev/rmt8 (drive 0, raw mode, 1600 bpi). This must be a raw mode tape device. n If the tape has a variable-length record format, then do not append a newline onto the end of the records. This option does not affect stream or FORTRAN files. s saveset Process only the given saveset number. t Produce a table of contents (a directory listing) on the standard output of the files on tape. v Verbose output. Normally vmsbackup does its work silently. The verbose option will cause the filenames of the files being read from tape to disk to be output on the standard output. w vmsbackup prints the action to be taken followed by file name, then wait for user confirmation. If a word beginning with `y' is given, the action is done. Any other input means don't do it. x extract the named files from the tape. The optional name argument specifies one or more filenames to be searched for specifically on the tape and only those files are to be processed. The name may contain the usal sh(1) meta-characters *?![] 0n. FILES

The filename match uses the complete VMS file names. AUTHOR

TCOPY(1)						    BSD General Commands Manual 						  TCOPY(1)

NAME
tcopy -- copy and/or verify mag tapes SYNOPSIS
tcopy [-cvx] [-s maxblk] [src [dest]] DESCRIPTION
The tcopy utility is designed to copy magnetic tapes. The only assumption made about the tape layout is that there are two sequential EOF marks at the end. By default, the tcopy utility will print information about the sizes of records and files found on the /dev/sa0 tape, or on the tape specified by the src argument. If a destination tape is also specified by the dest argument, a copy of the source tape will be made. The blocking on the destination tape will be identical to that used on the source tape. Copying a tape will yield the same program output as if just printing the sizes. The following options are available: -c Copy src to dest and then verify that the two tapes are identical. -s maxblk Specify a maximum block size, maxblk. -v Given the two tapes src and dest, verify that they are identical. -x Output all informational messages to the standard error instead of the standard output. This option is useful when dest is given as /dev/stdout. SEE ALSO
mt(1), mtio(4) HISTORY
The tcopy command appeared in 4.3BSD. BUGS
Writing an image of a tape to a file does not preserve much more than the raw data. Block size(s) and tape EOF marks are lost which would otherwise be preserved in a tape-to-tape copy. End of data (EOD) is determined by two sequential EOF marks with no data between them. There used to be old systems which typically wrote three EOF's between tape files. The tcopy utility will erroneously stop copying early in this case. When using the copy/verify option -c, tcopy does not rewind the tapes prior to start. A rewind is performed after writing, prior to the ver- ification stage. If one does not start at the beginning-of-tape (BOT) then the comparison may not be of the intended data. BSD
