I'm using MySQL GUI tool to backup my innodb database and I use the option '--single-transaction' to get a consistent copy as backup.

I have however, noticed that if I backup using command line mysqldump tool, the backup process speeds up noticeably. I am wondering if is possible to mention --single-transaction in command line mysqldump utility?

Sure enough, --single-transaction is supported from the MySQL command line.

mysqldump --single-transaction databasename

Will use all of the default options from --opt (except for --lock-tables, which is overridden by --single-transaction) as well as --single-transaction.

That really should be all there is to it.

I recommend briefly reading through all of the options of mysqldump - you may find that some of them, like --routines, are important for your database.

  • I know it's an old answer but I add this comment if other finds this. I have really tried to find out from the MySQL manuals if --single-transaction overrides --lock-tables. I couldn't find a clear statement otherwise than The --single-transaction option and the --lock-tables option are mutually exclusive. Perhaps it's obvious, but I rely on this answer. I hope it's still the case. MySQL 5.7.29.
