For production use, it is strongly recommended to use native database-specific tools instead of the XML backup service. XML backups are not guaranteed to be consistent, as the database may be updated during the backup process. Inconsistent backups are created successfully without any warnings or error messages, but fail during the restore process. Database-native tools offer a much more consistent and reliable means of storing data.
These pages describe common problems with XML backups for those who must use them, but it is strongly recommended to use database-native tools instead as outlined in our backup documentation.
