How to make a copy of a tape to another tape?
Hello,

We need to make a copy of a backup tape, using the 2 tape recorders in IBM 3582 Tape Library

We tried tu use "tcopy", it seems to work fine (no error messages) but we aren't sure if we can rely on it.

my question is how to check if the copy succeded or not, but i also want to know if there's a better way to do the copy (maybe the command dd )

Thx

tcopy

tcopy(1)							   User Commands							  tcopy(1)

NAME

       tcopy - copy a magnetic tape

SYNOPSIS

       tcopy source [destination]

DESCRIPTION

       The  tcopy  utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the
       contents of a tape is that there are two tape marks at the end.

       When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files.  If a des-
       tination  is  specified,  tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro-
       duces the same output as it does when only scanning a tape.

       The tcopy utility requires the use of Berkeley-compatible device names. For example,

       example% tcopy /dev/rmt/1b /dev/rmt/2b
