I am surprised at this, because we discovered some time back that the
ZZNET and nmrnet protocols are reliable only with data files, or at
least with files that are a multiple of the block size in length.
When you send an extended parameter file, for instance, and then
retrieve it, the size is different and the nmr program won't recognize
it. It was a big disappointment. We now use kermit to do actual
backups of such system files. It's slow, but the files are the same
when they come back. Some file types may work fine, but be careful
and check that you can actually use the files you have backed up and
restored.
