Can you please share the full error message. " MySQL server has gone away" usually comes when your mysql server is not available – georgecj11 Jan 12 '14 at 16:09

I've see at least two problems: 1. fields list doesn't match values. 2. serialized data doesn't quoted properly.

May be you have try native mysqldump instead of "Backup wizard"?

mysqldump \
--opt                  \
--no-create-db         \
--comments             \
--complete-insert      \
--order-by-primary     \
DATABASENAME  > ./dbdump.sql

Keep in mind that there is no space between -p and PASSWORD.

I solved the problem this way: set max_allowed_packet = 4M to the file my.ini
