Artifact Registry는 RPO 및 RTO가 낮은 재해 복구에 유용합니다. 비동기 복제에 대한 자세한 내용은 비동기 복제 정보를 참조하세요.
제한사항
기본 디스크와 보조 디스크의 크기는 동일해야 합니다. 활발하게 복제 중인 기본 디스크 크기를 조절하면 보조 디스크 크기가 자동으로 조절됩니다. 보조 디스크 크기를 자동으로 조절할 수 없는 경우 기본 디스크와 동일한 크기로 수동으로 조절해야 합니다. 보조 디스크 크기가 기본 디스크와 동일한 크기가 될 때까지 복제가 일시중지됩니다.
일관성 그룹에서 기본 디스크를 클론할 수 없습니다. 기본 디스크를 개별적으로 클론해야 합니다. 그러나 일관성 그룹에서 보조 디스크를 클론할 수 있습니다.

To learn\nmore about asynchronous replication, see\n[About Asynchronous Replication](/compute/docs/disks/async-pd/about).\n\nLimitations\n\n- Primary and secondary disks must be the same size. If you resize a primary disk that is actively replicating, then the secondary disk is automatically resized. If the secondary disk fails to resize automatically, then you must manually resize it to the same size as the primary disk. Replication is paused until the secondary disk is the same size as the primary disk.\n- You can't clone primary disks from a consistency group. You must clone primary disks individually. However, you can clone secondary disks from a consistency group.\n\nBefore you begin\n\n- [Create a primary disk](/compute/docs/disks/async-pd/configure#create_a_primary_disk).\n- [Create a secondary disk](/compute/docs/disks/async-pd/configure#create_a_secondary_disk).\n- If you haven't already, set up [authentication](/compute/docs/authentication). Authentication verifies your identity for access to Google Cloud services and APIs. To run code or samples from a local development environment, you can authenticate to Compute Engine by selecting one of the following options:\n\n Select the tab for how you plan to use the samples on this page: \n\n Console\n\n\n When you use the Google Cloud console to access Google Cloud services and\n APIs, you don't need to set up authentication.\n\n gcloud\n 1.\n [Install](/sdk/docs/install) the Google Cloud CLI.\n\n After installation,\n [initialize](/sdk/docs/initializing) the Google Cloud CLI by running the following command:\n\n ```bash\n gcloud init\n ```\n\n\n If you're using an external identity provider (IdP), you must first\n [sign in to the gcloud CLI with your federated identity](/iam/docs/workforce-log-in-gcloud).\n | **Note:** If you installed the gcloud CLI previously, make sure you have the latest version by running `gcloud components update`.\n 2.
