Pay close\n attention to our notes on how to [SQL database discovery considerations](#discover).\n\n- Install the Backup and DR Service agent on the database hosts.\n\n- Make sure the database permissions are set correctly.\n\nSQL database discovery considerations\n-------------------------------------\n\n- backup/recovery appliances support Microsoft SQL Server on Microsoft Windows\n server.\n\n- Discovery relies on SQL VSS writer. For the discovery to work correctly, SQL\n VSS writer must be installed and running on the host.\n\n- Appliances can manage Microsoft SQL Servers, SQL instances,\n consistency groups of SQL Server databases, and SQL availability groups.\n\n- For a SQL failover appliance, the discovery needs to be run on\n either the active node---or node IP---or appliance node---or\n appliance IP. Otherwise, clustered databases aren't discovered.\n\nAdd the host\n------------\n\nAdd the host to the management console. If the host has already been added, then\nedit the host and make sure to set all the configurations correctly.\n| **Note:** If you have added the Windows server to Backup and DR Service as a Compute Engine instance or as a VMware VM, then a host for this VM already exists and you don't need to add it again using the following procedure. Instead, find and edit that host.\n\n1. Click **Manage** \\\u003e **Hosts** , then click **+ Add Host**.\n\n2. On the **Add Host** page, complete the following:\n\n - **Name**: Provide the database server name.\n\n - **IP Address** : Provide the database server IP and click the\n **plus sign (+)**.\n\n - **Appliances**: Select the checkbox for the appliance.\n\n - **Host Type** : Make sure this is **Generic**.\n\n3. Click **Add** at bottom right to add the host. The host is added.\n\n4. Right-click the host and select **Edit**.\n\n5. Leave the **Staging Disk Format** as **Block**.\n\n6. Enter the username and password that you set up in\n **Application Discovery Credentials**.\n\n7. Select **Save**.\n\nDiscover SQL Server instances and databases\n-------------------------------------------\n\nUse the following instructions to discover SQL Server instances and databases:\n\n1. Click **App Manager** \\\u003e **Applications** , select\n **Add Application**.\n\n2. Select **SQL Server** on the **Add Application** page, then select the\n SQL Server database host. If you have many hosts, you can use the\n search feature or use the filter to see only hosts that are managed by\n a specific backup/recovery appliance.\n\n | **Note:** When adding SQL instances that participate in Microsoft Server Failover Clusters, either: \n | Run the wizard once for each node in the cluster, or else \n | Add all applications and multi-select all nodes at once. With this method, apply protection from the **Applications Listing** view by selecting **Manage Backup Plan** for the SQL instance.\n3. Select the host and click **Next**.\n This runs the discovery on the SQL Server host and discovers all SQL Server\n instances and databases running on it.\n\n | **Note:** Discovery on any one node adds other nodes of cluster as well. \n | To discover system DBs, run discovery on each node. System DBs can be protected as part of a SQL instance. \n | Availability Group databases can be protected as part of a SQL AG application. \n | You can take a backup image of a secondary by specifying the AG backup preference from application advanced settings. \n | Log truncation on the primary is managed by SQL Server, even when backing up db or logs on a secondary.\n\nFind the discovered instances and databases in the App Manager\n--------------------------------------------------------------\n\nTo find the newly-discovered database, go to the **App Manager Applications**\nlist. All applications known to the management console of all types are listed.\nUse the **Type** application filter to show only SQL Server\ndatabase instances. The new SQL Server instances and databases appear in the\nlist as unmanaged---the shield icon.\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)\n\nWhat's Next\n-----------\n\n[Configure backup plans for Microsoft SQL Server instances and databases](/backup-disaster-recovery/docs/backup/back-up-sql-server)"]]
