Summary 
This article describes how to create, verify, and run a recovery plan for standby forest in Cayosoft Guardian. Standby forest is a copy of the production Active Directory forest created with a scheduled process automated with Cayosoft Guardian.
With a recovery plan for standby forest, the whole standby forest update process can be performed unattendedly. A recovery plan for standby forest allows recovering a set of selected domain controllers to a pre-configured recovery site using regularly created backups of domain controllers. Such a recovery plan discovers the latest backups, automatically creates a new recovery site, performs recovery to that site, performs post-recovery health checks, and shuts down virtual machines after a successful recovery.
If a critical event occurs, you don't need to perform full forest recovery as you already have a ready-to-use standby forest. Cayosoft Guardian allows keeping multiple recovery sites that are ready to use in case of emergency.
Create a recovery plan for standby forest 
Before creating a recovery plan for standby forest:
- Add a valid Azure subscription where Azure recovery sites will be created
- Create a backup plan with a schedule that matches the schedule of the recovery plan you are going to create so that each time a recovery plan executes, it will be able to find new backup files
- Run a backup plan created at the previous step manually at least once
To create a recovery plan:
- Open Cayosoft Guardian Web Portal
- Expand Forest Recovery node
- Click on the Recovery Plans node
- Press Add button and select Recovery plan for standby forest option
- Select Active Directory forest to be recovered
- Select Azure subscription
- Select a recovery date using Recover to this point in time
- After confirmation, Cayosoft Guardian will discover the latest backups and automatically assign these backups to each domain controller to be recovered
Configure a recovery plan for standby forest
The recovery plan consists of a list of domain controllers, domain controllers recovery settings, actions settings, and general plan settings. The values of some settings are populated from the backup automatically.
Cayosoft Guardian automatically populates a list of domain controllers and their settings such as IP addresses, DNS-related settings, new DSRM passwords, and other settings that are required for successful recovery.
Cayosoft Guardian also populates Recovery site settings that are necessary for recovery site creation. A recovery plan for standby forest creates a new recovery site with each run and deletes the oldest recovery site after a successful recovery.
On execution of a recovery plan for standby forest, Cayosoft Guardian checks backups validity. If backups are older than the maximum backup age, the backup plan run will be canceled.
