280911 2004-10-13 20:13:00 I'm using the free back Up utility on XP to back up a PC . Several PCs back up to the computer in question (about three hours prior) .

The back ups are going to tape . What confuses me just a tad is that if the media fails to mount and the operation is aborted, why does it still back up 14 gig and take 3 and a half hours?

Content being backed up has changed . Should I consider erasing the tapes, deleting the catalogues? I haven't used this utility previously and despite searching microsoft and googling, haven't found anything helpful .


I've posted the report log below .

Do you have something "Spare" you can attempt to restore on.

or some way of integrity checking the tape .

It could just be an odd displayed incorrect error, or a real problem, it has obviously written something to the tape.

280913 2004-10-14 00:41:00 This looks like a case of misleading error messages . Such things do occur . ;-)

You may have written "RECEPTION-Fri-08- . . . . [etc]" on the case of the tape . But unless there has been a tape label block written to the tape, the hardware doesn't know .

This is old technology . The tape label is used as a protection against accidents . The OS/backup software relies on it to know who owns the tape, when it was written, when it can be overwritten, who can read the tape . . .

So what happens is this:

(1) you have told it to use "Media name RECEPTION-Fri-08 . . . [etc]"

(2) the software looks for a tape label block at the very start of the tape . If it's a new tape there might not be one, or there might be a default one .

(3)Anyway, it didn't find one containing the label "RECEPTION-Fri-08 . . . ", so it complains . On a mainframe, there would be an operator command which actually writes a suitable label to the tape and the OS would automatically look again, and start the backup when it finds the correct label . Since this is not a mainframe, with trained operators, it probably just gives a warning . . . giving you a chance to realise that you have put the wrong tape on . . . then it will have timed out then automatically written a label block and started the backup .

If you mount that tape, it should tell you that it has that "Media name" now . And the 14 GB are probably all there . ;-)

280914 2004-10-14 01:15:00 P.S. Just looked at the last line of the logfile again ... I'd strongy suggest you check the tape contents ... (not just "catalogs" on disk). Look for a "Label" command in the backup software though I guess it would automatically do it as I suggested. Does the tape appear in "My Computer"? See if you can explore it ... and see what the tape is labelled. Graham L (2)
