I've made backups of my site before and I never had these lines in them:
/*!40101 SET SQL_MODE=@OLD_SQL_MODE */;
/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */;
/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */;
/*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */;
/*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */;
/*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */;
/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */;
This appears in the .sql file that my host backed up for me(it was too large for me, cpanel or phpmyadmin).
I moved the dababase to another server and was having errors with those lines, so I just deleted them. Everything imported just fine, but I have a feeling that something might be missing.
Do these do anything important? The database went from 4.1 to 5.0
