[Dump-users] simple question about dumps to regular files

[Brent B. <br...@ke...>]

Suppose I have some dumps that were dumped with '-b64' block size 64KB, 
and they were dumped as regular files to disk.  Now I decide I want to 
send them to tape.  What kind of blocking/reblocking things do I have to 
worry about?  Should I:

cat dumpfile >/dev/nst0

 	or

dd if=dumpfile of=/dev/nst0

 	or

dd if=dumpfile of=/dev/nst0 bs=65536

...or something else I've not thought of here?  (If it makes any 
difference, I run my tape drive with variable size blocks.)
