• Specify the data transfer type if you launch the data transfer in the web console.
• Set the stop condition if you launch the data transfer by using the CLI or other developer tools.

​

Data transfer type (web console)

• One-time transfer: Data transfer is completed after just one iteration. One-time transfers are designed for data migration and backup.
• Replication: Iterations continue until you stop or delete the data transfer. Replications are designed for continuous synchronization between a source and a destination.

​

Stop condition (developer tools)

• .spec.after_one_iteration (same as the One-time transfer type): Transfer stops after completing its first iteration. The value should be an empty object.
  • CLI
  • Terraform

  {
    "spec": {
      "after_one_iteration": {},
      // Other parameters
    }
  }
  

  resource "nebius_storage_v1_transfer" "one_time_transfer" {
    stop_condition {
      after_one_iteration = true
    }
    # Other parameters
  }
  
• .spec.after_n_empty_iterations: Transfer stops after a number of consecutive empty iterations. For example, after five iterations:
  • CLI
  • Terraform

  {
    "spec": {
      "after_n_empty_iterations": {
        "empty_iterations_threshold": 5
      },
      // Other parameters
    }
  }
  

  resource "nebius_storage_v1_transfer" "empty_iterations_transfer" {
    stop_condition {
      after_n_empty_iterations {
        empty_iterations_threshold = 5
      }
    }
    # Other parameters
  }
  
• .spec.infinite (same as the Replication type): Transfer continues indefinitely until manually stopped.
  • CLI
  • Terraform

  {
    "spec": {
      "infinite": {},
      // Other parameters
    }
  }
  

  resource "nebius_storage_v1_transfer" "infinite_transfer" {
    stop_condition {
      infinite = true
    }
    # Other parameters
  }
  

​

Interval between iterations

{
  "spec": {
    "inter_iteration_interval": "<HhMmSs>"
    // Other parameters
  }
}

resource "nebius_storage_v1_transfer" "example_transfer" {
  inter_iteration_interval = "<HhMmSs>"
  # Other parameters
}
