Hi

How does the ZRM works?
We have Solaris10 redundant systems and we want a hot backup.
Does ZRM checks for the validity of database before we do backup and verifies if the backup image is not corrupt after backup s taken and before it is restored?
Do we have a manual which explains how ZRM works?
Where can I get additional details?

Thanks in advance.

Please see http://mysqlbackup.zmanda.com/ for information on how ZRM works and manuals.

Solaris10 cluster and hot backup are supported.

ZRM does not automatically check for database validity or backup image verification. You can do a pre-backup plugin to check validity of database before backup. ZRM provide backup image verification tool (mysql-zrm-verify-backup). You can run this after backup run as post-backup plugin or run it before restoration.

Hi

Does the ZRM maintain some backup record id or some specific info which can be referred while restore to ensure we are restoring the right image (preferably the latest image).

Are all the plugins available with the ZRM itself? Can we have them with the trial version of ZRM for testing?

Thanks

ZRM maintains necesary information to do restoration in the catalog.

Community version has LVM and ZFS snapshot plugin. Enterprise version supports more filesystem and storage snapshots (see http://www.zmanda.com/zrm-mysql-enterprise.html). Please contact zsales at zmanda dot com for evaluations
