Since InnoDB is the standard, i'd like to add the option `--single-transaction --quick` to the mysqldump command. This should speed up larger database exports without tearing the environment up whilst doing so... (see https://dev.mysql.com/doc/refman/5.7/en/mysqldump.html#option_mysqldump_single-transaction) Another way would be to allow for custom config to be loaded which inludes a optional `[mysqldump]` section... Another (even better perhaps) solution would be to have non-s3-backup command that utilizes the i.e. percona xtrabackup as the backup mechanism (and restore) but that changes from simple SQL backups to more advanced full database stuff...
