Backing up a VM with Hystax Acura Backup

Written by
Updated at May 7, 2025

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

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

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

  1. Get your cloud ready.
  2. Create a service account.
  3. Configure the network traffic permissions.
  4. Create a bucket.
  5. Create a VM with Hystax Acura Backup.
  6. Convert the VM IP address to static.
  7. Configure 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 recovery.

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

Get your cloud ready

Sign up in Yandex Cloud and create a billing account:

  1. Navigate to the management console and log in to Yandex Cloud or register a new account.
  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 and link a cloud to it.

If you have an active billing account, you can navigate 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 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.
  • Auxiliary Hystax Cloud Agent VMs use 2 vCPUs, 4 GB of RAM, and a 10-GB disk. A single Hystax Cloud Agent VM can serve up to six replicated disks at a time. If there are more than six disks, the system will automatically create additional Hystax Cloud Agent VMs.

For detailed system requirements, see the Hystax deployment reference.

The cost of resources for 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. You need an authorized key to perform operations in Yandex Cloud under a service account. Save the ID and private key. You will need these 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 these later.

Configure the network traffic permissions

Configure the network traffic permissions in the default security group.

Add the following rules to it:

Traffic
direction		 Description Port range Protocol Destination name /
Source		 CIDR blocks
Inbound http 80 TCP CIDR 0.0.0.0/0
Inbound https 443 TCP CIDR 0.0.0.0/0
Inbound https 4443 TCP CIDR 0.0.0.0/0
Inbound vmware 902 TCP CIDR 0.0.0.0/0

Outbound iSCSI 3260 TCP CIDR 0.0.0.0/0
Outbound udp 12201 UDP CIDR 0.0.0.0/0

Save the security group ID. You will need it later.

Note

Auxiliary Hystax Cloud Agent VMs are created automatically in the default security group. If you created a dedicated group for the Hystax Acura Backup VM, move the auxiliary Hystax Cloud Agent VMs to this group after their creation.

Create a bucket

  1. In the management console, select the folder where you want to create a bucket.
  2. Select Object Storage.
  3. Click Create bucket.
  4. On the bucket creation page:

    1. Enter a name for the bucket consistent with the naming requirements.

    2. Limit the maximum bucket size, if required.

      If the value is 0, the size is not limited. It is similar to the enabled No limit option.

    3. Select the access type:

      • Object read access: Restricted
      • Object listing access: Restricted
      • Read access to settings: Restricted

    4. Select the storage class: Standard.

    5. Click Create bucket to complete the operation.

  5. Save the bucket name. You will need it later.

Use the create REST API method for the Bucket resource or the BucketService/Create gRPC API call.

Create a VM with Hystax Acura Backup

To create a VM with a recommended configuration and a boot disk from the Hystax Acura Backup image:

  1. In the management console, select the folder where you want to create your VM.

  2. From the list of services, select Compute Cloud.

  3. In the left-hand panel, select Virtual machines.

  4. Click Create virtual machine.

  5. Under Boot disk image:

      • Click Add key.
      • Enter a name for the SSH key.
      • Upload or paste the contents of the public key file. You need to create a key pair for the SSH connection to a VM yourself.
      • Click Add.

      The SSH key will be added to your organization user profile.

      If users cannot add SSH keys to their profiles in the organization, the added public SSH key will only be saved to the user profile of the VM being created.

  11. Under General information, specify the VM name: hystax-acura-vm.

  12. Under Additional, select hystax-acura-account, the service account you created earlier.

  13. Click Create VM.

If you do not have the Yandex Cloud CLI yet, install and initialize it.

The folder specified when creating the CLI profile is used by default. To change the default folder, use the yc config set folder-id <folder_ID> command. You can specify a different folder using the --folder-name or --folder-id parameter.

Run this command:

yc compute instance create \
  --name hystax-acura-vm \
  --zone <availability_zone> \
  --cores 8 \
  --memory 16 \
  --network-interface subnet-id=<subnet_ID>,nat-ip-version=ipv4,security-group-ids=<security_group_ID> \
  --create-boot-disk name=hystax-acura-disk,size=200,image-id=<Hystax_Acura_Backup_image_ID> \
  --service-account-id <service_account_ID> \
  --ssh-key <public_SSH_key_file_path>

Where:

  • --name: VM name, e.g., hystax-acura-vm.
  • --zone: Availability zone, e.g., ru-central1-a. Save the availability zone ID, as you will need it later.
  • --cores: Number of vCPUs the VM has.
  • --memory: VM RAM size.
  • --network-interface: VM network interface description:
    • subnet-id: ID of the subnet to connect your VM to. You can get the list of subnets using the yc vpc subnet list CLI command. Save the subnet ID. You will need it later.
    • nat-ip-version=ipv4: Connect a public IP address.
    • security-group-ids: Security group. Use this parameter in case you configured this group previously. You can get the list of groups using the yc vpc security-group list CLI command. If you skip this parameter, the system will assign the default security group to the VM.
  • --create-boot-disk: Create a new disk for the VM:
    • name: Disk name, e.g., hystax-acura-disk.
    • size: Disk size.
    • image-id: Disk image ID. Use image_id from the product description in Cloud Marketplace.
  • --service-account-id: ID of the service account you created previously. You can get the list of accounts using the yc iam service-account list command.
  • --ssh-key: Path to the public SSH key file. The default username for SSH access is yc-user.

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

Convert the VM IP address to static

VMs get a public dynamic IP address when created. Since a VM with Hystax Acura Backup may reboot, convert its IP address to static:

  1. In the management console, open the dashboard of the folder you are using.
  2. Select Virtual Private Cloud.
  3. Navigate 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 address, as you will need it later.

If you do not have the Yandex Cloud CLI yet, install and initialize it.

The folder specified when creating the CLI profile is used by default. To change the default folder, use the yc config set folder-id <folder_ID> command. You can specify a different folder using the --folder-name or --folder-id parameter.

  1. See the description of the CLI commands for updating the address attributes:

    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 means the IP address with the e2l46k8conff******** ID is dynamic.

  3. Convert this address to 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 reserved is true, the IP address is static.

  4. Save the IP address, as you will need it later.

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

Configure Hystax Acura Backup

  1. In the management console, open the page of the Hystax Acura Backup VM and find its public IP address.

  2. Enter the VM’s public IP address in your browser. This will open the initial setup screen.
