Disaster Recovery

Disaster Recovery

All TrafficVision TMC data, configuration, settings, binaries, and dependencies are stored inside a single directory

On Linux: ~/trafficvision

TrafficVision TMC is designed to be copy-deployable without requiring setting up any databases or additional services.

Installation on CentOS7

Prerequisites

• Centos 7 with latest updates
• Configure firewall to allow inbound access to the port used by TrafficVision to serve clients (default 4443)
• A user account with sudo previleges (sudo previleges arerequired only during the installation)
• TrafficVision installer package (CentOS 7)

Steps

• Copy trafficvision installer package into user’s home directory
• Extract the installer package (e.g. tar xzf tmc-x.y.z.tar.gz)
  /home/$user/trafficvision
  /home/$user/deploy
• cd deploy
  ./setup-libs.sh
  ./setup-service-tmc.sh
  ./make-cert.sh
• cd ~/trafficvision/bin
  ./tmc_server
  Enter number of streams to be processed on this box
  Enter units (feet or meters)
• Send the ~/trafficvision/lic_req file to TrafficVision
• Put the tv_lic file that trafficvision sent in ~/trafficvision
• To start/stop TrafficVision: sudo systemctl start/stop tmc
• A customer can install SSL certificates in ~/trafficvision/certs (server.crt and server.key)

DISASTER RECOVERY

Option-1: DR using a stand-by server

• TrafficVision will provide licenses for both servers (production and stand-by).
• The redundant/stand-by server will need to be configured for network access to the cameras.
• A nighlty job will sync all the data and configuration from the production server to the stand-by server.
• During a Disaster the TMC service would need to be started on the stand-by server.
• All clients will need to be redirected to the stand-by server.

Option-2: DR using external backup and new/fresh server

• Customer will be responsible for backing up all the data from the trafficvision directory to the remote backup location.
• During DR, Customer will provision a server with similar hardware and OS specs as the production server running the TrafficVision software.
• Customer will be responsible for installing the TrafficVision software and restoring data from remote backup location onto the new server.
• Customer will send a license request file corresponding to the new server (generated during installation), unless the hardware for the disaster can be pre-selected and a license file can be generated in advance.
• TrafficVision will provide a license for the new server (either in advance or based on the disaster recover event).
