Restore MySQL Logical Backup

The ability to restore MySQL logical backups is a significant part of disaster recovery procedures. It’s a last line of defense.

Better Than Linear Scaling

 | April 22, 2017 |  Posted In: Hardware and Storage, High-availability, Insight for DBAs, Insight for Developers, MySQL
