My dumper is a free, open-source online backup tool for MySQL data that provides:

  1. Parallelism (hence, speed) and performance (avoids expensive character set conversion routines, efficient code overall)
  2. Easier to manage output (separate files for tables, dump metadata, and so on to view and parse data)
  3. Consistency: Maintains snapshots across all threads, provides accurate control and child log positions, so forth.

 

Set up BoostFS
Install BoostFS on the MySQL server to be backed up.
Create a mountpoint/backup and mount the DD Storage Unit using BoostFS.

 --compress/-c option
