 Most of you said that dd can do this. You were right. Giving the same command 7
times solved my problem. The command was :
 
 dd if=/dev/rmt/0cn of=/dev/rmt/1cn bs=63k
                                    ^^^^^^
 
I got the blocksize from first line of the ufsdump-log. It was :
 
 DUMP: Writing 63 Kilobyte records
 
P.S : Special thanks for

for sending me tapecv, tapecopy.sh , copytape . I learned too much from them.

P.S.S : I think, using tcopy 7 times does the same as well.

--- Original post ------

Hi,
 
I'm using ufsdump to backup my filesystems. I've a tape with 7 dumps and I need
to make a copy of this tape. I tried tcopy but I couldn't make the copy. I think
tcopy doesn't support tapes which has more than one dump file. And I know that
cpio doesn't support tapes dumped with ufsdump.

  How can I do that?
  
 P.S. : Solaris 2.6, sparc4, 4mm DDS-2
 P.S.S : I've two local tape drive.
