After running the command, the .BCK file with save sets looks good:

$ BACKUP/LIST STARTREK.BCK;3/save_set

I never had to deal with this back when I managed VMS on a VAX 11/780 at my old company, probably because we didn't deal with FTP back them.  And, for what it's worth, the FTP on my system seems to have issues with large blocksizes.  I take it that this is a known issue.

Where can you get the toolz CD now?  I've had no luck finding it online.

Thanks for the help!
