SSRS subscription jobs under SQL Server AgentUsing SQL Server 2008 R2 and SQL Server Reporting Services (SSRS)

When I schedule an SSRS report in SQL Server Reporting Services - Report Manager, it creates a subscription in SSRS.
In Microsoft SQL Server Management Studio under SQL Server Agent a new Job is added with a cryptic job name.
Please see attached snapshot for example.

How do I clean up those SSRS subcription jobs under SQL Server Agent?
For example, what if I only wanted to maintain 30 days worth of job history?
What procedure do I follow?

Thank you.

That "cryptic job name" is called a GUID, or a uniqueidentifier.

To limit the job history:

Right-hand click on SQL Server Agent
Go to Properties
Go to History

There you can limit the maximum job history log size (in rows), the maximum rows per job, and remove agent history older than X days/weeks/months.

Many of those SQL Agent jobs may be for expired subscriptions or no longer valid - we use the following query to determine if they can be safely removed:

   select c.Name as ReportName,
                  s.EventType,
                  s.Description as SubscriptionDescription,
                  s.LastStatus as LastSubscriptionStatus,
                  s.LastRunTime SubscriptionLastRunTime,
                  case
                     when recurrencetype = 1 then 'One Time'
                     when recurrencetype = 2 then 'Hourly'
                     when recurrencetype = 4 then 'Daily'
                     when recurrencetype = 5 then 'Monthly' 
                     when recurrencetype = 6 then 'Month Week' 
                     else 'Other'
                  end as RecurranceType,
                  s.DeliveryExtension,
                  u.UserName as SubscriptionSetUpBy,
                  s.ModifiedDate as SubscriptionLastModifiedDate
             from [ReportServer].[dbo].[Subscriptions] s
             join [ReportServer].[dbo].[Catalog] c
               on c.ItemID = s.Report_OID
             join [ReportServer].[dbo].[Users] u
               on u.UserID = s.OwnerID
             join [ReportServer].[dbo].[reportschedule] rs
               on c.itemid = rs.reportid 
              and s.subscriptionid = rs.subscriptionid
             join [ReportServer].[dbo].[schedule] sch
               on rs.scheduleid = sch.scheduleid
            where s.EventType <> 'RefreshCache'
              and s.LastRunTime < dateadd(m,-3,getdate())
         order by c.name

It will list any jobs that haven't been executed in the past three months, and you can likely remove any of those safely (though it includes Username, so you can contact them to ensure it's not necessary to keep).
