It may help you decide whether the cluster I/O or the virtual tape drive is the culprit crashing your VAX. Make the VAX disk large enough. Cluster mount it. Do the backup entirely from the Alpha using MSCP I/O.

I’m not sure what will happen if you try restore ODS-5 files to a ODS-2 disk. That’s something I’ve not tried.
Interesting, it wasn’t just the VAX that I crashed. I just realized I also crashed the Alpha.
