Connecting resources you need to back up to Cloud Backup
To back up your Yandex Compute Cloud VMs, BareMetal servers, or other resources in Cloud Backup, you need to connect these resources to Cloud Backup and set them up properly.
You connect a resource you need to back up by installing the Cloud Backup agent to its operating system. Depending on the type of resource you need to back up, the agent can be installed either automatically or manually.
For more information about connecting various types of resources to Cloud Backup, see these sections:
- Connecting Compute Cloud VMs.
- Connecting BareMetal servers.
- Connecting VMs and servers from outside Yandex Cloud.
Operating systems supported by Cloud Backup
Automatic installation of the Cloud Backup agent is available only for Yandex Compute Cloud VMs and Yandex BareMetal servers with particular operating systems. For more information, see Connecting a Compute Cloud VM and Connecting a BareMetal server.
You can install the Cloud Backup agent manually on all supported types of resources. For a complete list of operating systems supporting agent installation, see the backup provider guides.
Technical requirements for resources to back up
The minimum resource specification required to install and correctly run the Cloud Backup agent is as follows:
-
Free disk space:
- For Linux-based VMs: 2 GB.
- For Windows-based VMs: 1.2 GB.
-
RAM: For backups, 1 GB of RAM is required per 1 TB of backup. The RAM requirement depends on the amount and type of data processed by the Cloud Backup agent.
Tip
Installing a Cloud Backup agent is a resource-intensive operation. If you want to use a VM in the minimum possible configuration or, for example, a VM with a vCPU performance level below 100%, we recommend increasing the VM's resources during the Cloud Backup agent installation.
To speed up data backup and recovery, the Cloud Backup agent tends to consume significant amounts of RAM of the resource it is backing up. The agent can even use up all the available RAM, which in some cases may disrupt the resource's other services and make it impossible to complete the backup or recovery process.
To prevent such issues, limit the amount of data the agent caches in RAM.
Note
Limiting the Cloud Backup agent's use of RAM may slow down the backup and recovery operations.
