ZRM 3.9.3 Release Notes :
Enhancements : ZRM has been Upgraded to support TLS 1.2 and 1.3 versions.
It is now officially released and can be downloaded from network.zmanda.com
Downloading the package:
Login to your account and download the ZRM server installer from the Downloads section.
Note: There is no update to the client binaries. But if you are using the 3.8 client, please upgrade to the 3.9 client package available in Downloads.
Pre-Upgrade Checks:
1. 3.8 and 3.9 versions can be upgraded to 3.9.3 directly. If you are using an older version of ZRM, please reach out to Zmanda Support.
2. Before upgrading to the latest version, please take a backup of “/etc/mysql-zrm” directory. All the backupset configurations are stored here and will help you restore ZRM to a previous state in case of any failure during upgrade.
3. Collect the ZRM server logs using the “zm-support” script in the “/opt/zmanda/zrm/bin/” directory. The script collects a “mysqldump” of the ZRM database and other configuration files.

2. Choose to keep the console data and log files when prompted.
3. Copy the new installer to the ZRM server and provide execute permission to the .run file
# chmod +x ZRM-enterprise-3.9.3-installer-linux.run
4. Run the installer file as the root user
# ./ZRM-enterprise-3.9.3-installer-linux.run
5. Choose Y at the next prompt to copy the data from the previous installation.
7. Once the installation is complete, check if all the services are up and running,
