Dear Yehavi:

My guess is the /block qualifier on the RMU Backup command may be
higher than 32256 block size. Just like the VMS Backup, you can
specify a /block value higher than 32256 for disk-to-tape but the
saveset can not be copy back to disk from tape without problems. Check
to see if the /block value is higher than 32256, if it is then change
it to 32256. This change will increase the elapsed time on the RMU
Backup. However, your will be able to copy from tape to disk and disk
to tape w/o any problems.

I hope helps! Good Luck!
