-- Database size growth as a pivot table -- Transact-SQL script to analyse the database size growth using backup history. /* This Transact-SQL script uses the backup history to analyse the growth of the databases size over last twelve months and expose the average size of each month per database in a pivot table. The values are useful for future resource planning of the storage and backup system. Works with MS SQL Server 2005 and higher versions in all editions. Requires access and select permissions to the msdb system database. */ -- Transact-SQL script to analyse the database size growth using backup history.
