Tape to Tape copy

Managers,

I am wondering the best way to copy a backup of a filesystem from one tape
to another. The backup is done using a "tar" command with the block size set
to 1024.

I have been trying to use the "dd" command to copy tape1 to tape2 and then
trying to read tape2 back to no avail.

However a tar command with no block size set needs the dd command to have a
blocksize of 10240 in order for me to read the tar back on tape2.

Does anyone know of how I can get this to work with the backup taken with a
1024 block size both with using the tar command and also using the vdump
command? or indeed any other recommended way of copying a backup from one
tape to another?


Thanks in advance

Steve Copper
