Creating a backup policy

Written by

Updated at October 17, 2024

Creating a policy becomes available after you activate Cloud Backup.

After activation, the system automatically creates the following backup policies:

Default daily: Daily incremental VM backup with the last 15 backups retained.
Default weekly: Weekly incremental VM backup with the last 15 backups retained.
Default monthly: Monthly incremental VM backup with the last 15 backups retained.

Note

Backups are created according to the local time of the VM. There may be a slight delay in the schedule depending on the current service load.

Management console

CLI

Terraform

API

In the management console, select the folder where you want to create a backup policy.
In the list of services, select Cloud Backup.
Go to the Backup policies tab.
Click Create policy.
On the backup policy creation page:
- Enter a name. The naming requirements are as follows:
  - The name must be from 3 to 63 characters long.
  - It may contain lowercase Latin letters, numbers, and hyphens.
  - The first character must be a letter and the last character cannot be a hyphen.
- In the Create backups field, select how often backups should be created:
  - Every hour.
  - Every day: Specify the time for creating backups.
  - Every week: Specify the days of the week and time for creating backups.
  - By month: Specify the months, days of the month, and time for creating backups.
- Select the type of backup:
  - Incremental: Only data that differs from a previous backup is saved.
  - Full: All VM's data is saved.
- Select the policy for backup retention:
  - Retain all backups: All backups created under this backup policy will be retained.
  - Only the last: Specify the number of recent backups you want to retain or the number of days, weeks, or months for which to retain the backups. All other backups are deleted automatically.
  If you create the policy via the management console, subsequent changes of backup retention rules will take effect as soon as you create another backup.
Click Save.

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.

See the description of the CLI command to create a backup policy:
```
yc backup policy create --help
```

Specify the configuration of the backup policy you are creating as a data schema in JSON format.

Sample configuration file

  "format": "AUTO",
  "multiVolumeSnapshottingEnabled": true,
  "preserveFileSecuritySettings": true,
  "reattempts": {
    "enabled": true,
    "interval": {
      "type": "SECONDS",
      "count": "30"
    },
    "maxAttempts": "30"
  },
  "silentModeEnabled": true,
  "splitting": {
    "size": "1099511627776"
  },

    "rules": [
      {
        "maxCount": "10"
      }
    ],
    "beforeBackup": true
  },
  "scheduling": {
    "backupSets": [
      {
        "time": {
          "weekdays": [
            "MONDAY"
          ],
          "repeatAt": [
            {
              "minute": "5"
            }
          ],
          "type": "WEEKLY"
        }
      }
    ],
    "enabled": true,
    "maxParallelBackups": "2",
    "randMaxDelay": {
      "type": "MINUTES",
      "count": "30"
    },

    "weeklyBackupDay": "MONDAY"
  },
  "cbt": "ENABLE_AND_USE",
  "fastBackupEnabled": true,
  "quiesceSnapshottingEnabled": true
}

Save the configuration to a .json file.

The example describes a configuration for a backup policy that will create incremental VM backups every Monday at 00:05 (UTC+0). Only the last 10 backups will be stored.

See the full backup policy specification for details.

Create a backup policy:

yc backup policy create \
  --name <policy_name> \
  --settings-from-file <path_to_configuration_file>

Where:

--name: Name of the backup policy you are creating.
--settings-from-file: Path to the backup policy configuration file in JSON format.

Terraform allows you to quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. Configuration files store the infrastructure description in the HashiCorp Configuration Language (HCL). Terraform and its providers are distributed under the Business Source License.

For more information about the provider resources, see the documentation on the Terraform website or the mirror.

If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

If you don't have Terraform, install it and configure the Yandex Cloud provider.

Create resources:
1. In the terminal, change to the folder where you edited the configuration file.
2. Make sure the configuration file is correct using the command:
```
terraform validate
```
  If the configuration is correct, the following message is returned:
```
Success! The configuration is valid.
```
3. Run the command:
```
terraform plan
```
  The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.
4. Apply the configuration changes:
```
terraform apply
```
5. Confirm the changes: type yes in the terminal and press Enter.
Terraform will create all the required resources. You can check the new resources using the management console or this CLI command:
```
yc backup policy list
```

To create a backup policy, use the create REST API method for the Policy resource or the PolicyService/Create gRPC API call.
