Backup Meta-Data

I'm working on a PowerShell script to show me the trending durations of my backup activities. The first thing I need is the data, so I looked at the Standard Reports in SQL Server Management Studio, and found a report that suited my needs, so I pulled out the script that it runs and modified it to this T-SQL Script.

A few words here - you need to be in the MSDB database for this to run, and you can add a WHERE clause to limit to a database, timeframe, type of backup, whatever. For that matter, I won't use all of the data in this query in my PowerShell script, but it gives me lots of avenues to graph:

SELECT distinct t1.name AS 'DatabaseName'

,(datediff( ss, t3.backup_start_date, t3.backup_finish_date)) AS 'DurationInSeconds'

,t3.user_name AS 'UserResponsible'

,t3.name AS backup_name

,t3.description

,t3.backup_start_date

,t3.backup_finish_date

,CASE WHEN t3.type = 'D' THEN 'Database'

WHEN t3.type = 'L' THEN 'Log'

WHEN t3.type = 'F' THEN 'FileOrFilegroup'

WHEN t3.type = 'G' THEN 'DifferentialFile'

WHEN t3.type = 'P' THEN 'Partial'

WHEN t3.type = 'Q' THEN 'DifferentialPartial'

END AS 'BackupType'

,t3.backup_size AS 'BackupSizeKB'

,t6.physical_device_name

,CASE WHEN t6.device_type = 2 THEN 'Disk'

WHEN t6.device_type = 102 THEN 'Disk'

WHEN t6.device_type = 5 THEN 'Tape'

WHEN t6.device_type = 105 THEN 'Tape'

END AS 'DeviceType'

,t3.recovery_model

FROM sys.databases t1

INNER JOIN backupset t3

ON (t3.database_name = t1.name )

LEFT OUTER JOIN backupmediaset t5

ON ( t3.media_set_id = t5.media_set_id )

LEFT OUTER JOIN backupmediafamily t6

ON ( t6.media_set_id = t5.media_set_id )

ORDER BY backup_start_date DESC

I'll munge this into my Excel PowerShell chart script tomorrow.
