Backing Up Drive Manifests
Drive manifests can be automatically backed up to blobs by setting the BackupDriveManifest property to true in the Put Job or Update Job Properties operations. By default the drive manifests are not backed up. The drive manifest backups are stored as block blobs in a container within the storage account associated with the job. By default, the container name is waimportexport, but you can specify a different name in the ImportExportStatesPath property when calling the Put Job or Update Job Properties operations. The backup manifest blob are named in the following format: waies/jobname_driveid_timestamp_manifest.xml.
You can retrieve the URI of the backup drive manifests for a job by calling the Get Job operation. The blob URI is returned in the ManifestUri property for each drive.
