Yes.  This is a bug in Zenith's 3.3+ Backup.  I ran into it the first weekend
in October.  The problem is apparently that Backup is opening the file in
text mode causing translation of LF's to CR/LF's.  October is coded as an LF.
The same problem will occur on the 10th of any month.

The fix is trivial.  Open the file in text mode, read the file in, delete the
file, create it in binary mode, then dump the data back out.  I will email you
the source to the program I wrote to fix the backups.  If anyone else needs
it let me know, I'll be happy to email the source to you.
