SQL Azure Continuous Backup

SQL Azure Continuous Backup is one the two main methods for backing up databases which run  on  SQL Azure. Continuous Backup enables developers to backup a database on a continuous basis – as in the backup will not function as a standalone database but must be restored to the original database (in contrast to the Clone Backup which can be used as a separate standalone database).

Continuous Backup is slated for release in late 2010.
