You can restore a local file system, mapped\nNFS file system, or mapped SMB file system to its original host,\noverwriting the existing file system.\n\nFile system restoration\n-----------------------\n\nWhen you restore a file system, the backup/recovery appliance:\n\n- Replaces any files on the production disk with the version from the backup image.\n- Adds to the production disk any files that are in the backup image, even if they are no longer on the production disk.\n- Leaves in place any files on the production disk that are not in the backup image.\n\nIn rare cases in which the production data resides on a disk or on an external\nstorage pool presented by the backup/recovery appliance, restores replace the\nentire volume or block device, so the file system reverts to exactly what it was\nat the time of backup: Any files on the production disk that are not in the\nbackup image will no longer be on the production disk after restore.\n\nThe amount of time required to complete a restore operation depends on the\namount of data involved.\n\nRestore a file system\n---------------------\n\nUse these instructions to restore a file system from a backup image.\n\n1. From the Backup and DR Service management console, click\n **App Manager** and select **Applications** from the drop-down menu.\n\n The **Applications** page opens.\n2. Select the image that you want to restore, and then choose **Access** from\n the drop-down list at the bottom of the **Applications** page.\n\n The **Access** page opens listing captured images in the timeline ramp view.\n For more information on the view, see\n [Access the timeline ramp view of an image](/backup-disaster-recovery/docs/access-data/access-image-copy-data-list#access-time).\n | **Note:** If you are restoring an NFS image, the **Advanced NFS Settings** must only be changed after consulting with your support representative.\n\n A warning dialog opens.\n3. Read it and then enter `DATA LOSS` to confirm.\n\n4. Depending on your configuration, a second warning may appear. If so,\n you need to enter `OVERWRITE OTHER APPS` to confirm the restore operation.\n\n The restore job starts. You can verify that the restore operation is\n successful by viewing the job status in **Monitor**.\n\nRestore a mapped SMB file system\n--------------------------------\n\nUse these instructions to restore a point-in-time mapped SMB file system image.\n\n1. From the Backup and DR Service management console, click\n **App Manager** and select **Applications** from the drop-down menu.\n\n The **Applications** page opens.\n2. Select the mapped image that you want to restore.\n\n3. Choose **Access** from the drop-down list.\n\n The **Access** page opens listing captured images appear\n in the timeline ramp view.

Select an image, then select **Restore** from the list of\n access operations.\n\n The **Restore** page opens.\n5. Select a single volume or multiple volumes to restore. By default\n all volumes are selected.\n\n6. Click **Submit**.\n\n A warning dialog appears.\n7. Read the dialog and enter `DATA LOSS` to confirm.\n\n8.

You can verify that the restore operation is\n successful by viewing the job status in **Monitor**.\n | **Note:** If you need a different username or password to access the SMB share during restore than was used during data capture---perhaps you had to change the password between the captured and restore process---you can click **Details \\& Settings** and modify the application-specific settings to add a new username or password---see [Configure application settings for file systems](/backup-disaster-recovery/docs/backup/configure-app-settings-for-filesystems).\n\nRestore a mapped NFS file system\n--------------------------------\n\nUse these instructions to restore a mapped NFS file system image.\n\n1. From the Backup and DR Service management console, click\n **App Manager** and select **Applications** from the drop-down menu.\n\n The **Applications** page opens.\n2.
