Creating bootable tapes/backup copy of Sun O.S boot tape

[melpar!hoth at uunet.uu.net]

I would like to know if anyone has had success in creating a backup copy
of the Sun O.S boot tape(s).  I have tried the command:

# dd if=/dev/rst0 count=100 of=ostape1	--> to copy the tape to disk

which copied approximately 36 megabytes from the tape to the disk and,

# dd if=ostape1 of=/dev/rst0    --> to copy the disk file to tape

This produced a tape with 36 megabytes of information on it, but attempts
to boot from this tape failed.

Please E-Mail the response to: melpar!hoth
Thanks
