Upgrading Zmanda to the Latest and All-Powerful 4.1 Version

At Zmanda, we’ve been making major updates to our enterprise customers for a long time. At each step of our journey, we’ve listened to your feedback on our releases and worked to incorporate that knowledge into a release structure that works best for your organization. This input has translated into iterations on our release approach, changes to our release cadence, the introduction of all-new Zmanda 4.1 that includes many new features like support for vaulting in AWS Cloud Storage, powerful VMware file-level recovery, support for lighting-fast containerized deployments, Azure Cloud Storage support for backup, and so much more.

We understand that upgrading and migrating to newer versions take time and effort, so we are making that simple for you. In this article, we’ll run you through the installation process to upgrade your Zmanda to the latest power-packed Zmanda 4.1 version.

mv /var/lib/amanda-1/disk/* /var/lib/amanda/disk/

mv /var/lib/amanda-1/vtapes/* /var/lib/amanda/vtapes/
