How to verify the file was successfully encrypted...

Why do you need to use gpg for this task when you only need a symmetric
cipher. You would be better off going to CPAN (perl) and download AES
(Advanced Encryption Standard) module and use all of the features coming
with it or use libcrypt (used by gnupg) and use this. The other
solution, I can think off (if you use linux), is making encrypted pseudo
file system (file) of requested size (size of CD/DVD or other backup
medium) and copy the data on this file system (it is transparent). When
you finis this move the pseudo file system (file) to your backup medium.
