A backup repository is also used to store records of\nbackups, backup plans, restore plans, and restores.\n\nBefore you begin\n----------------\n\nTo create a backup repository, you must have the following:\n\n\u003cbr /\u003e\n\n- A compatible endpoint available.\n- A previously [created bucket](/distributed-cloud/hosted/docs/latest/gdch/platform/pa-user/create-storage-buckets) to use as the backup repository.\n- You have [granted access](/distributed-cloud/hosted/docs/latest/gdch/platform/pa-user/grant-obtain-storage-access) for the object storage bucket.\n- The necessary identity and access role:\n\n - Organization Backup Admin: manages backup resources such as backup and restore plans in user clusters. Ask your Organization IAM Admin to grant you the Organization Backup Admin (`organization-backup-admin`) role. For more information, see [Role\n definitions](/distributed-cloud/hosted/docs/latest/gdch/platform/pa-user/iam/role-definitions).\n\nCreate a repository\n-------------------\n\nCreate a repository by using the GDC console or the API. \n\n### Console\n\n1. Sign in to the GDC console.\n2. In the navigation menu, click **Backup for Clusters**. Ensure no project is selected in the project selector.\n3. Click **Create repository**.\n4. Enter a repository name. The description is optional.\n5. In the **Main cluster (read/write)** list, choose a cluster.\n6. In the **Linked clusters (read only)** list, choose the linked clusters.\n7. In the **S3 URI endpoint** field, enter an endpoint containing the fully-qualified domain name of your object storage site.\n8. In the **Bucket name** field, enter the name of the fully qualified name of the bucket, which can be found from the status of the GDC bucket custom resource.\n9. In the **Bucket region** field, enter the region where the bucket was created.\n10. In the **Access Key ID** list, enter the access key ID.\n11. In the **Access key** field, enter the access key.\n12. Click **Create**.\n\n### API\n\n\nTo use the backup and restore APIs, you must configure a valid\n`ClusterBackupRepository` custom resource to be the location of your\nbackups, and supply the required credentials.\n\n1. Fetch the secret generated in [Grant and obtain storage bucket access](/distributed-cloud/hosted/docs/latest/gdch/platform/pa-user/grant-obtain-storage-access#getting_bucket_access_credentials).\n\n2. Add a `ClusterBackupRepository` custom resource to use these credentials\n and apply the new resource to the Management API server.\n Backup repositories are cluster-scoped:\n\n apiVersion: backup.gdc.goog/v1\n kind: ClusterBackupRepository\n metadata:\n name: user-1-user\n namespace: user-1-user-cluster\n spec:\n secretReference:\n namespace: \"object-storage-secret-ns\"\n name: \"object-storage-secret\"\n endpoint: \"https://objectstorage.google.gdch.test\"\n type: \"S3\"\n s3Options:\n bucket: \"fully-qualified-bucket-name\"\n region: \"us-east-1\"\n forcePathStyle: true\n importPolicy: \"ReadWrite\"\n\n This example includes the following values:\n\nBackup repository import policies\n---------------------------------\n\nAll clusters must have at least one `ReadWrite` repository to successfully use backup and restore features. `ReadOnly` repositories are optional, have no\nlimit, and are used to gain visibility into other cluster backups for\ncross-cluster restores.\n\n`ReadOnly` repositories cannot be used as storage locations for additional\nbackups or for backup plans within the cluster they were imported.\n\nImporting a repository as `ReadWrite` claims the repository for that cluster,\npreventing other clusters from importing the same repository as\n`ReadWrite`. After importing a `ReadWrite` repository, all records of previous\nbackups, backup plans, and restores in that repository are imported into the\ntarget cluster as local custom resources.\n\nImporting a repository as `ReadOnly` does not claim the repository, it only\nimports the backups, backup plans, restores, and restore plans. Backup plans in read-only repositories don't schedule backups,\nthey exist to provide visibility into what backup plans exist in the cluster you are importing from. Removing a `ReadOnly` repository cleans up any imported resources from\nthe cluster and has no effect on the resources in the storage location as no write operations occur to object storage for read-only repositories.\n\nWhen a `ReadWrite` repository is removed from the cluster:\n\n- All local custom resources associated with that repository, such as backups and restores, are removed from the current cluster.\n- That cluster's claim on the repository is removed, allowing the repository to be used as `ReadWrite` by another cluster. However, these resources are not removed from the storage endpoint.\n\nWhat's next\n-----------\n\n- [Customize backup and restore for an application](/distributed-cloud/hosted/docs/latest/gdch/platform-application/pa-ao-operations/cluster-backup/customize-backup-restore)\n- [Plan a set of backups](/distributed-cloud/hosted/docs/latest/gdch/platform-application/pa-ao-operations/cluster-backup/plan-backups)"]]
