Send Alert when no log backup completed in 24 hours

  • Dear Forum,

    I'm sure someone has completed this type of request, but here is the back ground.

    I have a thrid party tool to complete all forms of backups on SQL databases. I have recently found that from time to time this 3rd party backup tool will drop a backup schdule. For example I have a instance where Transaction Log backups have not occured in months. So now I must Mirco manage the backups across some 600 instances.

    My questions does any have the code or an example on how send or create an alert if a database has not had a log backup with in the last 24 hours?

    All Enviroments are either 2K8 or 2K8R2.

    Any help or direction would be gladly execpted.

    Fishing for help..:hehe:

  • -- GET DATABASES WITHOUT FULL OR TLOG BACKUPS

    -- dbs with no full backups in last week

    (select cast(a.[name] as varchar(100)) as db_nm into #no_full_backup

    from master.dbo.sysdatabases a

    left join msdb.dbo.backupset b

    on a.[name] = b.database_name and datediff(hour,b.backup_finish_date,getdate())<168 -- 1 week

    and b.type='D'

    where a.[name] != 'tempdb'

    and databasepropertyex(a.[name], 'isinstandby') = 0

    and databasepropertyex(a.[name], 'status') = 'online'

    and databasepropertyex(a.[name], 'updateability') = 'read_write'

    and b.database_name is null )

    -- dbs with no transaction log backup for a day

    (select cast(a.database_name as varchar(100)) as db_nm into #no_tlog_backup

    from

    (

    select [name] as database_name

    from master.dbo.sysdatabases

    where databasepropertyex([name], 'recovery') in ('FULL','BULK_LOGGED')

    and databasepropertyex([name], 'isinstandby') = 0

    and databasepropertyex([name], 'status') = 'online'

    and databasepropertyex([name], 'updateability') = 'read_write'

    and [name] not in ('model','tempdb')

    ) a

    left join msdb.dbo.backupset b

    on a.database_name = b.database_name and b.type='L' and datediff(hour,b.backup_finish_date,getdate())<24

    where b.database_name is null)

    --select * from #no_full_backup

    --select * from #no_tlog_backup

    if (select count(*) from #no_full_backup) > 0

    raiserror ('databases with no full backups in last 7 days exist',16,1) with log

    if (select count(*) from #no_tlog_backup) > 0

    raiserror ('databases with no transaction backups in last 1 days exist',16,1) with log

    drop table #no_full_backup

    drop table #no_tlog_backup

    This one is actually SQL2000 compatible but works on other versions. You would be well to get the database status values from table master.sys.databases

  • to expand on what george posted you can create a procedure and schedule an agent job to run it. the procedure would also email the results (if any) using sp_send_dbmail http://msdn.microsoft.com/en-us/library/ms190307.aspx

    im currently working on some example code and will post when im done

    EDIT:

    Here is a rough sample and will probably need to be tweaked to make it work specifically as you want so it will email you through the dbmail system if there is an error. you would just set up an agent job to run the SP once a day

    CREATE PROCEDURE usp_NoTlogBackup (@Length INT)

    AS

    DECLARE @BadDatabases VARCHAR(8000)

    DECLARE @Body VARCHAR(8000)

    SELECT @BadDatabases = STUFF(

    (select ', ' + cast(a.database_name as varchar(100))

    from

    (

    select [name] as database_name

    from master.dbo.sysdatabases

    where databasepropertyex([name], 'recovery') in ('FULL','BULK_LOGGED')

    and databasepropertyex([name], 'isinstandby') = 0

    and databasepropertyex([name], 'status') = 'online'

    and databasepropertyex([name], 'updateability') = 'read_write'

    and [name] not in ('model','tempdb')

    ) a

    left join msdb.dbo.backupset b

    on a.database_name = b.database_name

    and b.type='L'

    and datediff(hour,b.backup_finish_date,getdate()) < @Length

    where b.database_name is null

    FOR XML PATH ('')

    ),1,2,'')

    IF (@BadDatabases IS NOT NULL)

    BEGIN

    SET @Body = 'On ' + @@SERVERNAME + ' The following Databases do not have Tlog backups: ' + @BadDatabases

    EXEC msdb.dbo.sp_send_dbmail @profile_name = 'profile_name',

    @recipients = 'your@email.com',

    @from_address = 'ServerName@from.com',

    @body = @Body

    END

  • we actually schedule our check via SCOM, so if you have an enterprise monitoring tool like SCOM you would hopefully be able to plug the script into it.

  • Have a look at Policy Based Management.

    I set my policies up as "On Demand", and schedule the evaluations from a Central Management Server. This allows me to check my 2005 servers as well.

    But as you say all your servers are 2008+, you could create them with "On Schedule" evaluation modes so that each instance checks itself regularly. A failure results in an error in the log, which can be alerted on using a SQL Agent Alert.

  • Thank you everyone for your fast response and code posting, now with a quit afternoon(not likely). I can get this loaded throughout my universe.

  • Out of curiosity can you post which solution you used once you get one in place?

  • Sorry for the late response to your request to know which code set I used. The answer is sorry none, part of process are in ultra secure enviroments and server level email would be a strict no-no, and would case what is known as a Resume generating event(RGE).

    and are instances have grown to 1300 since this posting.

    the final process was a set of SSIS packages that collected requested information, and then we are using SSRS to allow management and application owners to see what is happening. it is crude but meets the need.

    Thank you for the information.

  • i do this with Powershell. Job runs every morning, and checks to see if a backup, full or differential, has been run in the last 24 hours. Also checks to see if a full backup is more than a week old, in case we are running differentials instead of full backup. it also checks to see if the db has FULL recovery, and if so, checks to see if the transaction log is more than 24 hours old. Loops through all of my servers, and then emails if backup is old or if it can't connect to a server. i have attached a zip file, with the Powershell code. this version is used to run from a SQL Agent job. You will need to update how the servers are retrieved. i put them in a table.

    Only the server that runs the report needs to have ability to smtp.

    You also need to make sure your job can connect to all of your other servers. i have a proxy set up to do that.
