SQL-DMO Examples: Backup and Restore

This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.

Backup and restore examples illustrate performing common Microsoft SQL Server database and log backup and restore operations by using SQL Distributed Management Objects (SQL-DMO).

For SQL Server, backup operations can create a stable image of an entire database or some discrete part of the database. A backup can contain all data in a database or only that data modified since the last backup. Selection of a backup methodology is based on application implementation details, such as size of a database or transaction rate, and will vary from one instance of SQL Server to another. For more information about selection of a backup strategy, see Backing Up and Restoring Databases.

Backup and restore operations performed by using the Backup and Restore objects can be long-running and can require user intervention to complete, such as changing the tape in a tape device. SQL-DMO implements events on the Backup and Restore objects allowing user notification of backup progress and signaling on exhaustion of media. For more information about using SQL-DMO Backup and Restore object events, see Handling SQL-DMO Events.
