스냅샷 풀과 독립적으로 상주하는 SQL AlwaysOn 가용성 그룹에 복제하려면 SQL Server 데이터베이스 복제에 설명된 대로 SQL AlwaysOn 가용성 그룹의 각 노드에서 데이터베이스의 복제 작업을 실행합니다.
복원 후 데이터베이스의 복구를 선택 해제하고 각 클론 작업에 동일한 롤포워드 시간을 지정해야 합니다.
새 SQL Server AlwaysOn 가용성 그룹에 가상 데이터베이스 추가
새 AG의 모든 데이터베이스가 복구되면 SQL Studio 또는 T-SQL을 사용하여 데이터베이스를 SQL AlwaysOn 가용성 그룹에 추가합니다.
SQL Studio에서 SQL 가용성 그룹을 선택합니다.
데이터베이스를 가용성 그룹에 추가합니다.
다음을 클릭합니다. 동기화 방법을 선택하라는 메시지가 표시됩니다.
참여만을 선택합니다. 참여만 작업은 기본 데이터베이스와 보조 데이터베이스를 가용성 그룹으로 형성합니다.
작업 진행 상황을 모니터링합니다. 작업이 완료되면 기본 데이터베이스와 보조 데이터베이스가 모두 동기화됩니다.
자동 검색 애플리케이션이 사용 설정되어 있지 않으면 가용성 그룹 호스트에서 애플리케이션을 수동으로 검색합니다.
검색이 완료되면 데이터베이스가 앱 관리자에 SQL 가용성 그룹의 구성원으로 표시됩니다.
다른 데이터베이스와 마찬가지로 가용성 그룹의 구성원을 캡처합니다.

The mounted application runs in\nthe snapshot pool, and achieves the same performance as data captured in the\nsnapshot pool.\n| **Note:** Be sure there is enough space in the snapshot pool for the availability group and regular snapshots.\n\n1. Mount the databases being added to the SQL availability group to each node\n in the AG, one node at a time. See\n [Mount a SQL Server database](/backup-disaster-recovery/docs/access-data/sql-access).\n\n2. Select the required host.\n\n3. Select the SQL instance.\n\n4. Specify the roll-forward time, being sure to specify the same time during\n mounts to each node.\n\n5. Under **Advanced Options** , deselect **Recover Database After Restore**.\n\n6. Enter a name, or a prefix or suffix. Use the same name, prefix, or\n suffix on all nodes.\n\n7. Repeat the process for each availability group member.\n\n8. Once all databases are mounted as virtual databases on each availability\n group node, using SQL, select the SQL instance that is the primary and for\n each database recover it:\n\n `recover database (name) with recovery`\n\n9. Keep the secondary database copies in restoring state.\n\n10. When the master database has been restored, using SQL, create the new\n availability group and join the primary and secondary databases as described\n in\n [Add virtual databases to a new SQL Server AlwaysOn Availability group](#AlwaysOn).\n\nClone to a SQL Server availability group independently from the snapshot pool\n-----------------------------------------------------------------------------\n\nTo clone to a SQL AlwaysOn Availability group that resides independently from\nthe snapshot pool, perform a clone operation for the databases on each node in\nthe SQL AlwaysOn Availability group as described in\n[Clone SQL Server databases](/backup-disaster-recovery/docs/restore-data/sql-cloning).\nBe sure to deselect **Recover** database after restore and to specify the same\nroll-forward time for each clone operation.\n\nAdd virtual databases to a new SQL Server AlwaysOn Availability group\n---------------------------------------------------------------------\n\nAfter all databases for the new AG have been recovered, use SQL Studio or T-SQL\nto add the databases to the SQL AlwaysOn Availability group:\n\n1. From SQL Studio, select the SQL availability group.\n\n2. Add the databases to the availability group.\n\n3. Click **Next** . You are prompted to select a synchronization method.\n Select **Join only** ; the **Join only** operation forms the primary and\n secondary databases into an availability group.\n\n4. Monitor the progress of the operation. When the operation is complete,\n both the primary and secondary databases are in sync.\n\n5. If autodiscover applications is not enabled, manually discover\n applications on the availability group host.\n\n6. After discovery is complete, the databases appear in the **App Manager** as\n members of the SQL availability group.\n\n7. Capture members of an availability group just like any other database.\n\nThe Backup and DR Microsoft SQL Server DBA guide\n------------------------------------------------\n\nThis page is one in a series of pages specific to protecting and recovering\nMicrosoft SQL Server databases with Backup and DR.\nYou can find additional information at:\n\n- [Backup and DR for Microsoft SQL Server Databases](/backup-disaster-recovery/docs/concepts/backupdr-for-sql-server)\n- [Prepare SQL Server databases for Backup and DR Service](/backup-disaster-recovery/docs/configuration/prepare-sql-server)\n- [Add a SQL Server database host and discover databases](/backup-disaster-recovery/docs/configuration/discover-sql-server)\n- [Configure backup plans for Microsoft SQL Server instances and databases](/backup-disaster-recovery/docs/backup/back-up-sql-server)\n- [Application details and settings for Microsoft SQL Server instances and databases](/backup-disaster-recovery/docs/backup/app-details-settings-sql-server)\n- [Mount a SQL Server database](/backup-disaster-recovery/docs/access-data/mount-sql-server)\n- [Mount databases into SQL Always On Availability Groups](/backup-disaster-recovery/docs/access-data/mount-sql-server-aag)\n- [Manage an active mount](/backup-disaster-recovery/docs/access-data/manage-active-mounts)\n- [Migrate a SQL Server database](/backup-disaster-recovery/docs/access-data/mount-and-migrate-sql-server-2)\n- [Clone SQL Server databases](/backup-disaster-recovery/docs/access-data/clone-sql-server)\n- [Recover SQL Server backups](/backup-disaster-recovery/docs/restore-data/restore-sql-server)"]]
