  • mydumper

    Official MyDumper Project

  • MySQLDump is too slow for that size- if you are going to logically export and import the db, use a parallel tool. The one I like is MyDumper, ( https://github.com/mydumper/mydumper ) but there are other alternatives. The compression and parallelism will get you a 5-20 speedup compared to the serial export and import. For small dbs and portable formats this is my preferred method.

  • symmetric-ds

    SymmetricDS is database replication and file synchronization software that is platform independent, web enabled, and database agnostic. It is designed to make bi-directional data replication fast, easy, and resilient. It scales to a large number of nodes and works in near real-time across WAN and LAN networks.
