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.

We have significantly improved the snapshot interface for doing MySQL backups using ZRM. This work has been released as part of ZRM 2.0. ZRM 2.0 has couple of snapshot plugins - Linux LVM and Solaris ZFS that uses the interface.

Changes in ZRM 2.0:
* Solaris packages
* ZRM clients for Linux (RPM/Debian) and Solaris
* Tested on Gentoo distribution
* Improved Snapshot plugin interface
* Solaris ZFS snapshot plugin
* Backup of remote servers using snapshots
* Asychronous checksum computation for improved backup performance
* Backup compression on the fly for logical backups

Download it from Zmanda downloads page and give it a try. I will write more about how to use the plugin interface next week.
