To know how the backup and restore process impacts the Managed Microsoft AD features and decide how to restore a domain, read the following sections.\n\nSQL Server integration\n----------------------\n\nFor restoring from a backup associated with SQL Server integration, consider the following:\n\n- If you experience some errors after you restore your domain from a backup with an SQL Server integration, you must reauthenticate the SQL Server instances that are already connected to the domain.\n\n- If you restore your domain from a backup taken before the SQL Server integration, you can observe some stale resources. You can either ignore or clean them up by [removing Windows Authentication from the SQL Server instances](/sql/docs/sqlserver/configure-ad#removing-windows-authentication-from-an-instance).\n\nTrust relationships\n-------------------\n\nFor restoring from a backup associated with trust relationships, consider the following:\n\n- If you restore your domain from a backup taken after creating the trust relationships, you must update the trust health by [validating the trust](/managed-microsoft-ad/docs/manage-trusts#validating-trust).\n\n- If you restore your domain from a backup taken before creating the trust relationships, you can observe stale entries that show as **Connected** in the **Trust relationships** section of the domain page. You must update the trust health by [validating the trust](/managed-microsoft-ad/docs/manage-trusts#validating-trust). You can then either delete the trust or [recreate the trust](/managed-microsoft-ad/docs/create-trust).\n\nDomain peerings\n---------------\n\nFor restoring from a backup associated with domain peerings, consider the following:\n\n- If you restore your domain from a backup with domain peerings, the domain peerings continue to exist and function as usual.\n\n- If you restore your domain from a backup taken before creating the domain peerings, the domain peerings continue to exist and function as usual. You must [delete the domain peerings](/managed-microsoft-ad/docs/list-describe-delete-domain-peering#delete_domain_peering) manually.\n\nWhat's next\n-----------\n\n- [Back up and restore a domain](/managed-microsoft-ad/docs/backup-restore).\n\n- [Create a trust with an on-premises domain](/managed-microsoft-ad/docs/create-trust).\n\n- To manage a one-way trust relationship between an on-premises domain and a Managed Microsoft AD domain, see [Manage trusts](/managed-microsoft-ad/docs/manage-trusts).\n\n- To integrate Microsoft SQL Server with Managed Microsoft AD, see [Connect Microsoft SQL Server](/managed-microsoft-ad/docs/how-to-use-sql-server)."]]
