Disaster Recovery

MetroAE offers robust disaster recovery options

Backup and Restore

MetroAE supports backup and restore for VSD and VSC.

There are two ways of using the backup command:

  • Use metroae backup everything to back up all supported components
  • Use metroae backup <component_type>to back up a specific component.

Restore installs a fresh copy of the components being restored. There are three ways to execute MetroAE restore:

  • Use metroae restore everythingto install and restore all supported components
  • Use metroae restore <component_type>to install and restore an individual component type (ex. metroae restore vsds)
  • You can use a combination of MetroAE commands to do a step-by-step install and restore. For example:
    • metroae restore vsds predeploy
    • metroae restore vsds deploy
    • metroae restore vsds postdeploy

Detailed information can be found in the documentation here.

HA Installation and Upgrade

MetroAE offers the installation and upgrade of VSP components in High-Availability (HA) configurations:

  • VSD Active/Standby Cluster
  • VSD Geo-Redundant Cluster
  • VSTAT Active/Standby Cluster
  • VSC Primary/Standby Pair
  • NUH HA Configuration

You can use the command metroae vsd failover to execute a VSD cluster failover. This operation will make the current standby cluster the active cluster and attempt to make the current active cluster the standby cluster. More information can be found in the documentation.
