---------------------------------------------
I've been using this trick to make copies of my backups to send
off-site. But now I'm faced with tapes created with dump rather than
tar. The dd command doesn't seem to be working as well for this. I've
fiddled with block size. As I understand it, dump's default block size
is 1024. I can't restore from copied tapes. The restore command can't
find a header file for the dump.
Does anyone have a command for copying one tape dump to another?
TIA
