# A Quick Look at Setting Up Disaster Recovery

Consider the most common use case, where you create two data grids, create a gridset, and add them to a gridset in the right order.

For more information about gridsets, see "Gridsets" in TIBCO ActiveSpaces® Concepts. The following sequence helps you set up a disaster recovery model.

# | Steps | References
--- | --- | ---
1 | Create a data grid with a name that is planned to be the primary grid (grid1). | Defining a Data Grid.
2 | Create a data grid with a name that is planned to be a mirror/DR grid (grid2). | Defining a Data Grid.
3 | Create at least one proxy in each data grid with the appropriate `proxy_mirroring_ static_listen_host` and `proxy_mirroring_static_listen_port` values to set the IP address and port for how other data grids communicate with this data grid. | Create a proxy by following the steps in Defining a Data Grid. To configure static mirroring host and port, see Configuring a Proxy with Static Mirroring Host and Port.
4 | Create a gridset by using the tibdg tool with the following command: `tibdg gridset create gridset1` | Creating a Gridset.
5 | Add the first data grid to the gridset (the first data grid added becomes the primary grid) by using the tibdg command: `tibdg gridset add gridset1 grid1 proxy_static_ip:proxy_static_port` | Adding Data Grids to a Gridset.
6 | Add the second data grid to the gridset (which becomes a mirror grid) by using the tibdg command: . `tibdg gridset add gridset1 grid2 proxy_static_ip:proxy_static_port` | Adding Data Grids to a Gridset.
7 | Start the data grids and create a checkpoint in the primary grid so that it is mirrored to the mirror grid. Perform the following steps: The primary grid must run a primary realm service A mirror grid must run a satellite realm service, which is achieved by specifying the following configuration file option: `satelliteof <primary realm URL list>` For details about realm services, see "Realm Service" in TIBCO FTL® Administration. For details about satellite realm services, see "Server Roles and Relationships in TIBCO FTL® Administration. | To start the data grid processes, see Starting the Data Grid Processes. To create a checkpoint, see Creating a Checkpoint. To understand mirroring, see the following: Automatic Mirroring. Setting Up a Planned Cutover to a Mirror Grid. Disaster Recovery at a Mirror Grid.
8 | In the event of a disaster, make the mirror grid the new primary grid by using the tibdg command:`tibdg gridset setPrimary gridset1 grid2` . | See Activating the Mirror Grid as the Primary Grid.
