Choose the Snapshot Manager image supported on Ubuntu or RHEL system that meets the Snapshot Manager installation requirements and create a host.

See Creating an instance or preparing the host to install Snapshot Manager.

Verify that you can connect to the host through a remote desktop.

See Verifying that specific ports are open on the instance or physical host.

Install Docker or Podman container platforms on the host.

See Table: Installing container platform.

Download the OS-specific Snapshot Manager image from the Veritas support site.

The Snapshot Manager image name resembles the following format for Docker and Podman environment:

NetBackup_SnapshotManager_<version>.tar.gz

Run the following command to prepare the Snapshot Manager host for installation:

# sudo ./flexsnap_preinstall.sh

For the VM based extension installed on a RHEL OS the SElinux mode should be "permissive".

Network Security Groups used by the host that is being protected should allow communication from the host where the extension is installed, on the specified ports.
