Database Growth History

By Nicholas Williams, 2013/05/07

Hello,

Pretty straight forward script. It pulls information about the growth of the databases on your server by looking at the backup tables in the msdb database. It provides info on a data and log file level and gives a percentage growth per file type.

Hope somebody else will find a use for it too.

Desc:		Calculates Growth Info for all databases on a server that are being backed up. Relies on the backup tables, and as a result will only contain as many
		days history as do the backup tables(@iNoSamples). If a database is not being backup up the results will be NULL. (For example the Tempdb)
		This is a rewrite of something I did a few years ago, as I dont know where I saved the other code. bummer.
