Can LiteSpeed backup a database when an update is in progress?
SQL Server, in conjunction with LiteSpeed, uses an online backup process to allow a database backup while the database is still in use. During a backup, most operations are possible; for example, INSERT, UPDATE, or DELETE statements are allowed during a backup operation. Operations that cannot run during a database or transaction log backup include: File management operations such as the ALTER DATABASE statement with either the ADD FILE or REMOVE FILE options. Shrink database or shrink file operations. This includes auto-shrink operations. For additional information, please see http://msdn2.microsoft.com/en-us/library/ms186865.aspx
