This\nbest practice simplifies backup management and can improve the performance of\nbackups.\n\nBefore you begin\n----------------\n\nTo manage a backup, you must have access to the following:\n\n- The necessary identity and access roles:\n\n - Harbor Instance Admin: has full access to manage Harbor instances in a project. Ask your Organization IAM Admin to grant you the Harbor Instance Admin (`harbor-instance-admin`) role.\n - Secret Admin: required for operating in the GDC console. Ask your Organization IAM Admin to grant you the Secret Admin (`secret-admin`) role.\n- An existing backup. You create backups from the following sources:\n\n - GDC creates backups automatically as defined in the backup plan schedule. For more information, see [Create a backup plan](/distributed-cloud/hosted/docs/latest/gdch/platform-application/pa-ao-operations/harbor-backup/create-backup-plan-harbor).\n - You create manual backups. For more information, see [Create a manual backup](/distributed-cloud/hosted/docs/latest/gdch/platform-application/pa-ao-operations/harbor-backup/create-manual-backup-harbor).\n\nView an existing backup\n-----------------------\n\nTo view an existing backup, follow these steps:\n\n1. Sign in to the GDC console.\n2. In the navigation menu, click **Backup for harbor instance**.\n3. Click **Backups**.\n4. View existing backups in the table.\n5. To view the details of a single backup, click the name of the backup in the table.\n\nDelete a backup\n---------------\n\nBackups are deleted in two ways:\n\n- Backups are automatically deleted after the number of days in their backup plan retention policy is reached.\n- You delete backups manually.\n\nTo manually delete an existing backup, follow these steps:\n\n1. Sign in to the GDC console.\n2. In the navigation menu, click **Backup for harbor instance**.\n3. Click **Backups**.\n4. Click the name of the backup you want to delete.\n5. Click delete**Delete backup**.\n6. In the confirmation dialog, enter the name of the backup that is being deleted.\n7. Click **Delete backup**.\n\n| **Warning:** The delete operation can't be undone. The deletion of this backup permanently removes the backup and all of its data. The creation of restores from this backup is no longer possible.\n\nWhat's next\n-----------\n\n- [Create a restore](/distributed-cloud/hosted/docs/latest/gdch/platform-application/pa-ao-operations/harbor-backup/create-restore-harbor)"]]
