Hmmm... did you actually try -k , as afio requested you to do? It might 
be helpful in some situations. Given you're somewhere in the middle of 
the tape, this would perfectly explain the message IMHO.

Other way 'round, however, maybe adding a "-v" to make afio a little 
more verbose also doesn't hurt. ;)

[flexbackup-help] I/O Error

2010-03-05 Thread Niall Brosnan
Hi André
Have you access to the flexbackup.conf from the old machine?
The archive may not even be in afio format. It may not be compressed with
gzip. It may not be compressed at all.
Depending on the admin's normal practice, they may have chosen cpio or tar
format as a preferred format.
Leave out as many of the buffer commands and flexbackup flags as you can for
now, and concentrate first on analysing your tape.
You could 'dd' a few blocks from the next archive into a 'file -' command to
get an opinion on format.
Try piping it into 'pax' for a listing, as it will also analyse and read
several formats.
Once you know what you have,
Adjust flexbackup.conf accordingly and it will allow you work with the
tapes.
I've used flexbackup for years on lots of platforms, and have been very
happy with it. The one 'gotcha' these days that stops me using it for home
directories is the seemingly unavoidable error with .gvfs directories for
gnome users.
Its local, remote and mirroring methods make for a great first tool to turn
to for regular backups and snapshots.
Hope you get your problem sorted,
Niall Brosnan
