ZRM Enterprise Edition 3.6 Release Notes

ZRM Enterprise 3.6 provides new functionality and has fixes for the issues reported by ZRM Enterprise customers (see the changes below). 

Compatibility with previous versions of ZRM Enterprise

  • ZRM Enterprise 3.6 Installer detects the existing installation of ZRM Enterprise 3.5.  Users can upgrade  from ZRM Enterprise 3.5 release automatically. Please save the configuration when prompted during the upgrade process.
  • It will be necessary to upgrade ZRM clients to 3.6 if you plan to use new backup method such as parallel logical backup using MyDumper command.

Upgrading to ZRM Enterprise 3.6

You can upgrade from ZRM server from 3.5 to 3.6 by running the ZRM server 3.6 installer. It will automatically detect the presence of earlier installation and prompt the user for the upgrade. The configuration will be preserved during upgrade. Before the upgrade process, it is important to make a copy of /etc/mysql-zrm/mysql-zrm.conf* files on the ZRM server. If there are changes to this file, they will have to manually merged. Please contact Zmanda support if you need help with the merge.

You can upgrade the ZRM client software on the clients by running package install program such as rpmdpkgpkgaddas appropriate for the platform. If the package manager does not provide an upgrade option, you can uninstall 3.5 package and install 3.6 package.

Users upgrading from releases earlier than ZRM 3.5 should contact Zmanda Support team. Zmanda offers Quick Upgrade services for customers who would like Zmanda to perform the upgrade from older releases.

Note: If you are planning to upgrading by uninstalling the 3.5 version and installing ZRM Enterprise 3.6, you must make a copy of /etc/mysql-zrm/mysql-zrm.conf* files on the ZRM server. Otherwise, the changes to these files will be lost (Site specific backup set configuration).

Compatibility with Amanda Enterprise

The Amanda backup server can reside on the same machine as the ZRM server.  Amanda Enteprise 3.3.x is compatible with ZRM server 3.6.  Please use the following procedure (order of steps is important):

  • Install Amanda 3.3.x or ZRM 3.6 server (i.e. install the first product if it is not installed)
  • Change permissions on /etc/zmanda directory on the backup server

# chmod 777 /etc/zmanda

  • Change permissions on the configuration files

# chmod 755 /etc/zmanda/*.cnf

  • Install ZRM 3.6/Amanda 3.3.x server (install the other product)
  • Change permissions on the configuration files that were installed in the last step

# chmod 755 /etc/zmanda/*.cnf

  • Restart the ZMC services in the following order

# /etc/init.d/zmc_aee stop

# /etc/init.d/zmc_zrm stop

# /etc/init.d/zmc_zrm start

# /etc/init.d/zmc_aee start

  • You should be able to configure Amanda and ZRM backup sets using ZMC

For installing ZRM 3.6 along with older versions of Amanda Enterprise, please contact Zmanda Support team before installation.

Note: Please ignore the message about the man page for zm-support tool is already installed when you are installing the second product.


  • Support for newer versions of Xtrabackup and MySQL Enterprise Backup.
  • Support for parallel logical backups. We leverage the mydumper command for this support. ZRM handles views, triggers and stored procedures separately during parallel logical backups. Users can also restore specific tables from full database backup images created by ZRM via mydumper.
  • Changes to ZMC Backup When page to prevent conflicts between full and incremental backup schedules.
  • Numerous bug fixes.


For a full list of supported platforms please review the compatibility guide here.

ZRM Enterprise 3.6 documentation provides detailed information on how to install and configure Amanda server and client on these platforms.

Known Issues

  • Network disruption during MySQL backup from a Windows server might cause the backup status not to be updated. The user will have to abort the backup in the ZMC manually.
