Installation

Before beginning the installation, review the Double-Take Availability requirements and Installation and upgrade notes. Use the installation instructions appropriate for the type of workload you are protecting

Data, full-server, and application workloads—If you are protecting a data workload, full-server workload, or an application workload, you can install using the standard installation program or the command-line automatic installation process.
Virtual workloads—You can also use the standard installation program or the command-line automatic installation process if you are protecting a virtual workload, however, if your source and target are both virtual machines on an ESX server and you want to protect the host-level virtual disk files, you need to install Double-Take Availability for VMware Infrastructure.
Clusters—If you are protecting a cluster, the installation will depend on the type of cluster configuration you are using. For standard clusters with a shared SCSI disk, use the standard installation program or use the command-line automatic installation process. For a GeoCluster configuration, where data is stored on volumes local to each node and replicated to each node in the cluster, you will need to configure your cluster appropriately and install Double-Take Availability.
