One of the significant features in version 2.0 of Zmanda Recovery Manager for MySQL is MySQL backups using Solaris ZFS. Doing MySQL backups using
filesystem snapshots has minimal impact on the MySQL databases. The MySQL databases are not available for updates for less than a second and the application impact is not dependent on the size of the database.
ZRM 2.0 can be downloaded from Zmanda downloads page. It supports all Linux and Solaris distributions. The documentation is available on ZRM wiki.
ZRM forums can be used to get questions answered about the project.
This article shows an example of how to install, configure, backup and restore MySQL databases using Zmanda Recovery Manager (ZRM) for MySQL on OpenSolaris. The example takes advantage of ZFS snapshots to do full backups.
