In my previous company, i was asked to track the growth rate of our database because we had a daily transaction table that gets updated everyday..

So i wrote the following procedure and it is also tested on SQL Server 7.0 & SQL Server 2000.

CREATE PROC sp_track_db_growth
(
@dbnameParam sysname = NULL
)
AS
BEGIN

/***********************************************************************************************************

Purpose: To calulate the file growth percentages for a given database and to show you the rate at which
your databases are growing, so that you can plan ahead for your future storage needs.


Tested on: SQL Server 7.0, SQL Server 2000


Usage: Run this script in the master database to create the stored procedure. Once it is created,
you could run it from any of your user databases. If the first parameter (database name) is
not specified, the procedure will use the current database.

Example 1:
To see the file growth information of the current database:

EXEC sp_track_db_growth

Example 2:
To see the file growth information for pubs database:

EXEC sp_track_db_growth 'pubs'

***********************************************************************************************************/

DECLARE @dbname sysname

/* Work with current database if a database name is not specified */

SET @dbname = COALESCE(@dbnameParam, DB_NAME())

SELECT CONVERT(char, backup_start_date, 111) AS [Date], --yyyy/mm/dd format
CONVERT(char, backup_start_date, 108) AS [Time],
@dbname AS [Database Name], [filegroup_name] AS [Filegroup Name], logical_name AS [Logical Filename],
physical_name AS [Physical Filename], CONVERT(numeric(9,2),file_size/1048576) AS [File Size (MB)],
Growth AS [Growth Percentage (%)]
FROM
(
SELECT b.backup_start_date, a.backup_set_id, a.file_size, a.logical_name, a.[filegroup_name], a.physical_name,
(
SELECT CONVERT(numeric(5,2),((a.file_size * 100.00)/i1.file_size)-100)
FROM msdb.dbo.backupfile i1
WHERE i1.backup_set_id =
(
SELECT MAX(i2.backup_set_id)
FROM msdb.dbo.backupfile i2 JOIN msdb.dbo.backupset i3
ON i2.backup_set_id = i3.backup_set_id
WHERE i2.backup_set_id < a.backup_set_id AND
i2.file_type='D' AND
i3.database_name = @dbname AND
i2.logical_name = a.logical_name AND
i2.logical_name = i1.logical_name AND
i3.type = 'D') AND
i1.file_type = 'D') AS Growth
FROM msdb.dbo.backupfile a JOIN msdb.dbo.backupset b
ON a.backup_set_id = b.backup_set_id
WHERE b.database_name = @dbname AND
a.file_type = 'D' AND
b.type = 'D'

) as Derived
WHERE (Growth <> 0.0) OR (Growth IS NULL)
ORDER BY logical_name, [Date]

END

Not sure if you knew this but you can actually post scripts to the Script section on this site for others to find and use long term so, you might want to check that out. Left hand side of the page, select Scripts and I think there is a link to post them there.

Thanks for sharing!

Nice job.

But in 2005 and 2008 you could do it using CTE (Common table Expressions) instead of dierived tables, because the script costs much time if there is a great numberes of backups done.

Thanks anyway

Agree with all it is a nice script for 2K and under. Well done!

Unfortunately we never do backups so it would be moot here
