It's fixed!!! Recap: large RT database (host Ubuntu 14.04LTS, database server MySQL 5.7.x on Windows Server 2012). Backup .sql files became truncated at ~18GB when the database is easily 20GB.
It looks like (for whatever reason) the max_allowed_packet option is not carrying over to the backup scripts. I re-wrote my backup options as: -u USER -h HOST --max_allowed_packet=512M --single_transaction > output.sql That solved it. And I get a full backup of the file. Probably my own fault, but wanted to share the information. I'm now getting 19.5GB+ backups. Thanks to everyone! Stephen Cena Senior Systems Administrator Quality Vision International, Inc.
