Prerequisites to install the extension on VM

Choose the NetBackup Snapshot Manager image supported on Ubuntu or RHEL system that meets the NetBackup Snapshot Manager installation requirements and create a host.
See Creating an instance or preparing the host to install NetBackup 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 NetBackup Snapshot Manager image from the Veritas Technical Support website.
The NetBackup 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 NetBackup Snapshot Manager host for installation:
# sudo ./flexsnap_preinstall.sh
Note:
The actual file name varies depending on the release version.
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.
