Backing up a VM with Hystax Acura Backup

Written by
Updated at October 30, 2024

You can create VM backups automatically and recover them in your cloud infrastructure using Hystax Acura Backup in Yandex Cloud.

A VM with Hystax Acura Backup manages the backup and recovery processes. VM backups are saved to an Object Storage bucket. Recovery is performed using an auxiliary Hystax Cloud Agent VM. It creates a new VM with a certain RPO (recovery point objective) at a point of time in the past. Backup RTO (recovery time objective) depends on the amount of source data.

To back up and recover a VM using Hystax Acura Backup:

  1. Prepare your cloud.
  2. Create a service account.
  3. Configure network traffic permissions.
  4. Create a bucket.
  5. Create a VM with Hystax Acura Backup.
  6. Make the VM IP address static.
  7. Set up Hystax Acura Backup.
  8. Prepare and install an agent on the VM.
  9. Create a VM backup.
  10. Create a disaster recovery plan.
  11. Run the recovery process.

If you no longer need the resources you created, delete them.

Prepare your cloud

Sign up for Yandex Cloud and create a billing account:

  1. Go to the management console and log in to Yandex Cloud or create an account if you do not have one yet.
  2. On the Yandex Cloud Billing page, make sure you have a billing account linked and it has the ACTIVE or TRIAL_ACTIVE status. If you do not have a billing account, create one.

If you have an active billing account, you can go to the cloud page to create or select a folder for your infrastructure to operate in.

Learn more about clouds and folders.

Note

Note that both the Hystax Acura Backup infrastructure and all the recovered VMs will be charged and counted against the quotas.

  • A Hystax Acura Backup VM uses 8 vCPUs, 16 GB of RAM, and a 200-GB disk.
  • The auxiliary Hystax Cloud Agent VMs use 2 vCPU cores, 4 GB or RAM, and a 10-GB disk. A single Hystax Acura Cloud Agent VM can serve up to 6 replicated disks at the same time. If there are more than 6 disks, additional Hystax Acura Cloud Agent VMs are created automatically.

For detailed system requirements, see the Hystax documentation.

The cost of the resources required to use Hystax Acura Backup includes:

Create a service account and access keys

Hystax Acura Backup will run under a service account.

  1. Create a service account named hystax-acura-account with the editor and marketplace.meteringAgent roles. Save the service account ID. You will need it later.
  2. Create an authorized key for the service account. An authorized key is required to perform operations in Yandex Cloud as a service account. Save the ID and private key. You will need them later.
  3. Create a static access key. A static key is required to access a bucket as a service account. Save the ID and secret key. You will need them later.

Configure network traffic permissions

Use the create REST API method for the Instance resource or the InstanceService/Create gRPC API call.

Make the VM IP address static

VMs are created with a public dynamic IP. Since a VM with Hystax Acura Backup may reboot, make the IP static.

  1. In the management console, open the page for the folder you are using.
  2. Select Virtual Private Cloud.
  3. Go to the IP addresses tab.
  4. Click in the row with the address of your Hystax Acura Backup VM.
  5. In the menu that opens, select Make static.
  6. In the window that opens, click Change.
  7. Save the IP. You will need it later.

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.

  1. See the description of the CLI update address attribute command:

    yc vpc address update --help

  2. Get a list of available addresses:

    yc vpc address list

    Result:

    +----------------------+------+-----------------+----------+------+
|          ID          | NAME |     ADDRESS     | RESERVED | USED |
+----------------------+------+-----------------+----------+------+
| e2l46k8conff******** |      | 84.201.155.117  | false    | true |
+----------------------+------+-----------------+----------+------+

    The false value of the RESERVED parameter indicates that the IP address with the e2l46k8conff******** ID is dynamic.

  3. Make this address static by using the --reserved=true key and IP address ID:

    yc vpc address update --reserved=true <IP_address_ID>

    Result:

    id: e2l46k8conff********
folder_id: b1g7gvsi89m3********
created_at: "2023-05-23T09:36:46Z"
external_ipv4_address:
  address: 84.201.155.117
  zone_id: ru-central1-b
  requirements: {}
reserved: true
used: true

    Now that the reserved parameter is true, the IP address is static.

  4. Save the IP. You will need it later.

Use the update REST API method for the Address resource or the AddressService/Update gRPC API call.
