Windows Azure

Microsoft SQL Azure Database is the relational database service on
the Windows Azure platform. Once you have created a database in SQL Azure,
you can back up that database by copying it to a new database in SQL
Azure. The new database that is created from the copy process is a regular
database once the copy is complete: fully functioning and independent of
the source database. In addition, the new database will have the same edition
and maximum size as the source database.

Overview

The database copy feature enables many of the back-up scenarios you may be
familiar with for on-premises databases:

  • Application data back up: Copy the
    application database to a new database in order to help protect it from user and
    application errors. Recover the application database state by renaming the new
    database with the application database name. Alternatively, recover a specific
    subset of data from the new database by use of Transact-SQL
    queries.

  • Application development and testing: Copy
    the production database to a new database that can be used for development and
    testing.

  • Application upgrade: Copy the application
    database to a new database before major application updates. If a mistake is
    made during the upgrade, recover the earlier database state by renaming the new
    database to the application database name.

Nice!
