Backup Meta-Data
- by BuckWoody
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.
