Taking backups using mydumper


mydumper is a logical backup tool that's similar to mysqlpump.

mydumper has these advantages over mysqldump:

  • Parallelism (hence, speed) and performance (avoids expensive character set conversion routines and has efficient code overall).
  • Consistency. It maintains snapshots across all threads, provides accurate master and slave log positions, and so on. mysqlpump does not guarantee consistency.
  • Easier to manage output (separate files for tables and dumped metadata, and it is easy to view/parse data). mysqlpump writes everything to one file, which limits the option of loading selective database objects.
