Creating a Linux VM with a connection to Cloud Backup
You can back up Compute Cloud VMs with supported Linux-based operating systems.
For the Cloud Backup agent to run properly, VMs must meet the minimum requirements.
Getting started
Creating a VM
-
In the management console, select the folder where you want to create a VM.
-
In the list of services, select Compute Cloud.
-
In the left-hand panel, select Virtual machines and click Create virtual machine.
-
Under General information:
-
Enter a name and description for the VM. 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.
Note
The VM name is used to generate an internal FQDN only once: when creating a VM. If the internal FQDN is important to you, choose an appropriate name for the VM at the creation stage.
-
Select an availability zone to place your VM in.
-
-
Under Boot disk image, select an operating system supported in Cloud Backup.
-
Under Network settings:
- Choose a subnet in the selected availability zone.
- In the Public IP field, select
Auto. - Select a security group configured to work with Cloud Backup.
-
Under Access, select the service account with the
backup.editorrole. -
Under Additional:
- Enable Cloud Backup.
- Optionally, select a backup policy or click Create to create a new one.
-
Specify the other VM parameters as needed. For more information, see Creating a VM from a public Linux image.
-
Click Create VM.
When the VM switches to the Running status, a Cloud Backup agent will start installing on it. This may take from 5 to 10 minutes.
-
Select a folder:
yc resource-manager folder listResult:
+----------------------+--------------------+------------------+--------+ | ID | NAME | LABELS | STATUS | +----------------------+--------------------+------------------+--------+ | wasdcjs6be29******** | my-folder | | ACTIVE | | qwertys6be29******** | default | | ACTIVE | +----------------------+--------------------+------------------+--------+ -
Select a subnet:
yc vpc subnet list --folder-id <folder_ID>Result:
+----------------------+---------------------------+----------------------+----------------+-------------------+-----------------+ | ID | NAME | NETWORK ID | ROUTE TABLE ID | ZONE | RANGE | +----------------------+---------------------------+----------------------+----------------+-------------------+-----------------+ | b0c6n43f9lgh******** | default-ru-central1-d | enpe3m3fa00u******** | | ru-central1-d | [10.***.0.0/24] | | e2l2da8a20b3******** | default-ru-central1-b | enpe3m3fa00u******** | | ru-central1-b | [10.***.0.0/24] | | e9bnlm18l70a******** | default-ru-central1-a | enpe3m3fa00u******** | | ru-central1-a | [10.***.0.0/24] | +----------------------+---------------------------+----------------------+----------------+-------------------+-----------------+ -
Create a VM:
yc compute instance create \ --folder-id <folder_ID> \ --name <VM_name> \ --zone <availability_zone> \ --network-interface subnet-name=<subnet_name>,nat-ip-version=ipv4,security-group-ids=<security_group_ID> \ --create-boot-disk image-id=<image_ID>,size=<boot_disk_size> \ --cores 2 \ --core-fraction 100 \ --memory 4 \ --service-account-name <service_account_name> \ --ssh-key <path_to_public_SSH_key>Where:
-
--folder-id: Folder ID. -
--name: Name of the new VM.Note
The VM name is used to generate an internal FQDN only once: when creating a VM. If the internal FQDN is important to you, choose an appropriate name for the VM at the creation stage.
-
--zone: Availability zone matching the selected subnet. -
subnet-name: Name of the selected subnet. -
security-group-ids: ID of the security group configured to work with Cloud Backup. -
image-id: OS image ID. See the list of supported Linux-based operating systems for details. -
create-boot-disk: Boot disk size. -
--cores: Number of vCPUs in the VM. -
--core-fraction: Guaranteed vCPU share (in percentage). -
--memory: VM RAM amount. -
--service-account-name: Name of the service account with thebackup.editorrole. -
--ssh-key: Path to the file with the public SSH key. The VM will automatically create a user namedyc-userfor this key.
In this example, we are creating a VM running Ubuntu 20.04:
yc compute instance create \ --folder-id wasdcjs6be29******** \ --name my-vm \ --zone ru-central1-b \ --network-interface subnet-name=my-vpc-ru-central1-b,nat-ip-version=ipv4,security-group-ids=abcd3570sbqg******** \ --create-boot-disk image-id=fd8ecgtorub9********,size=25 \ --cores 2 \ --core-fraction 100 \ --memory 4 \ --service-account-name backup-editor \ --ssh-key my-key.pubResult:
done (46s) id: abcdho6nspdk******** folder_id: wasdcjs6be29******** created_at: "2023-10-09T14:57:06Z" name: my-vm ... one_to_one_nat: address: 158.***.**.*** ... placement_policy: {} -
-
Connect to the VM over SSH. Establish a connection as
yc-userand use the VM's public IP address from thecreate VMcommand output underone_to_one_nat. -
Install the Cloud Backup agent:
Ubuntu
sudo apt update && \ sudo apt install -y jq && \ curl https://storage.yandexcloud.net/backup-distributions/agent_installer.sh | sudo bashResult:
... Agent registered with id D9CA44FC-716A-4B3B-A702-C6**********CentOS
sudo yum install epel-release -y && \ sudo yum update -y && \ sudo yum install jq -y && \ curl https://storage.yandexcloud.net/backup-distributions/agent_installer.sh | sudo bashResult:
... Agent registered with id D9CA44FC-716A-4B3B-A702-C6**********
Note
If the Cloud Backup agent fails to install within 10 minutes, contact support to diagnose the issue.
Once you install the agent, the VM will be added to Cloud Backup in the Virtual machines tab and you will be able to link it to a backup policy. If you selected a backup policy when creating the VM, then the VM is already linked to the policy and no further action is required.
