I have 2 questions:
1) is it possible to list the contents of a tape without having written
the tape?
2) is it possible to extract a file from the tape without having put it
there to begin with?
I continually get tapes written in BACKUP format with no clue as to
the command(s) used to prepare the tape.whitfill@hc.DSPO.GOV (Jim Whitfill) (03/09/88)

You should be able to extract any file from a backup tape (as SYSTEM) whether or not you put it there. backup mta0:name/select=[directory]file * ======================================= Jim A.

Sure, you can do this: BACKUP/LIST=file tapedev:/save where file is a filename that will store the tape list, you can opt not to put the "=file" part after the list, in which case it will go to the terminal. tapedev: is your tape device name. Ours is MUA0: for either a TK-50 or a TU-81+, but it might be different for other types of tape drives. I have seen MTA0: on other sites. > > 2) is it possible to extract a file from the tape without having put it > there to begin with? I guess so. You may not get anything back from this type of restore. I guess what you are asking is does VMS complain if you try to restore a file from a saveset and that file is not in that saveset. If that is what you are asking, well VMS will not say nothing. Even if you do a BACKUP/LOG it will report nothing from this type of restore. > > I continually get tapes written in BACKUP format with no clue as to > the command(s) used to prepare the tape. When you do a BACKUP/LIST the begining part of that list will have a section of how that saveset was done, with even the actual command that did it.
