To restore an existing cluster from a backup:

1. Create a Terraform configuration file for the new cluster.

   Do not use the database (yandex_mdb_mysql_database) and user (yandex_mdb_mysql_user) resources: these will be restored from the backup.

2. Add a restore section to this configuration file:

   resource "yandex_mdb_mysql_cluster" "<cluster_name>" {
     ...
     restore {
       backup_id = "<backup_ID>"
       time      = "<time>"
     }
   }
   

   In the time parameter, specify the time point to restore the MySQL® cluster to in yyyy-mm-ddThh:mm:ss format starting from the selected backup's creation time.

   Note

   The time parameter is optional. If you do not specify it, the cluster will be restored to the state when the recovery process was started.

3. Make sure the settings are correct.

   1. Using the command line, navigate to the folder that contains the up-to-date Terraform configuration files with an infrastructure plan.

   2. Run the command:

      terraform validate
      

      If there are errors in the configuration files, Terraform will point to them.

4. Confirm updating the resources.

   1. Run the command to view planned changes:

      terraform plan
      

      If the resource configuration descriptions are correct, the terminal will display a list of the resources to modify and their parameters. This is a test step. No resources are updated.

   2. If you are happy with the planned changes, apply them:

      1. Run the command:

         terraform apply
         

      2. Confirm the update of resources.

      3. Wait for the operation to complete.

Terraform will create a copy of the existing cluster. The databases and users are deployed from the selected backup.

resource "yandex_mdb_mysql_cluster" "<cluster_name>" {
  ...
  timeouts {
    create = "1h30m" # 1 hour 30 minutes
    update = "2h"    # 2 hours
    delete = "30m"   # 30 minutes
  }
}

To restore a previously deleted cluster from a backup:

1. Create a Terraform configuration file for the new cluster.

   Do not use the database (yandex_mdb_mysql_database) and user (yandex_mdb_mysql_user) resources: these will be restored from the backup.

2. In this configuration file, add a restore section with the name of the backup to restore the cluster from:

   resource "yandex_mdb_mysql_cluster" "<cluster_name>" {
     ...
     restore {
         backup_id = "<backup_ID>"
     }
   }

   You can get the cluster ID with a list of clusters in the folder.

4. View the server response to make sure the request was successful.

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

To set a retention period for automatic backups, provide the required value in the --backup-retain-period-days argument of the cluster update command:

yc managed-mysql cluster update <cluster_name_or_ID> \
   --backup-retain-period-days=<retention_period_in_days>

The possible values range from 7 to 60. The default value is 7.

You can request the cluster ID and name with a list of clusters in the folder.

1. Open the current Terraform configuration file with an infrastructure plan.

   For more information about creating this file, see Creating clusters.

   For a complete list of available Managed Service for MySQL® cluster configuration fields, see the Terraform provider documentation.

2. To set a retention period for automatic backups, add a backup_retain_period_days block to the Managed Service for MySQL® cluster description:

   resource "yandex_mdb_mysql_cluster" "<cluster_name>" {
     ...
     backup_window_start: <retention_period_in_days>
   }
   

3. Make sure the settings are correct.

   1. Using the command line, navigate to the folder that contains the up-to-date Terraform configuration files with an infrastructure plan.

   2. Run the command:

      terraform validate
      

      If there are errors in the configuration files, Terraform will point to them.

4. Confirm updating the resources.

   1. Run the command to view planned changes:

      terraform plan
      

      If the resource configuration descriptions are correct, the terminal will display a list of the resources to modify and their parameters. This is a test step. No resources are updated.

   2. If you are happy with the planned changes, apply them:

      1. Run the command:

         terraform apply
         

      2. Confirm the update of resources.

      3. Wait for the operation to complete.
