bak_website: Now archiving http://mywebsite.com
ncftpget: server said: File successfully transferred
bak_website failed

-------------------------------=<(*)>=--------------------------------

On inspection I find the file was successfully transferred but mvarc
never executes. Shouldn't the message from the remote server set a
return code of zero? How can I capture ncftpget's return code?

val=$?
echo "return code=$val"

You might try adding the -d option to ncftpget. It could be that one or
more files were transferred successfully but some were not, or the ftp
server is not a Unix server.
