How to find dump file sizes for last night''s backups?

  • I have written this script to find the backup sizes for the most recent backups but it is giving me duplicate values. Before messing with it further I wanted to check if anyone has heard of any existing scripts or utilities to find the size of recent DB and Log backups. Thanks!

    SET NOCOUNT ON

    use msdb

    go

    select "DB_name" = convert(char(20), BS.database_name),

    BS.type,

    convert(char(20),BS.backup_finish_date,100) as end_time,

    BS.backup_size AS "backup_size in bytes",

    BF.file_size

    frombackupset BS(nolock),

    backupfile BF(nolock)

    where backup_start_date > (SELECT MAX(backup_start_date) FROM backupset) - 1

    ANDBS.backup_set_id = BF.backup_set_id

    order by database_name, backup_start_date

  • Try something like this:

     

    use msdb

    go

    select top 200 b.backup_set_id, b.backup_start_date, b.backup_finish_date,

              bm.physical_device_name,

        cast (((b.backup_size / 1024) /1024) / 1024 as decimal(16,2)) AS GB

    from backupset b join backupmediafamily bm

    on b.media_set_id = bm.media_set_id

    where b.type='d' and b.database_name = 'YourDBName'

       --and bm.physical_device_name = '\\.\tape0'

    order by b.backup_start_date desc

  • Thanks for your reply. I combined my script with yours to get the script below. Selecting backup_set_size I can now see that there are definitely duplicates. Any idea why? Thanks again...

    SET NOCOUNT ON

    use msdb

    go

    select top 50 BS.backup_set_id,

    "DB_name" = convert(char(20), BS.database_name),

    BS.type,

    convert(char(20),BS.backup_finish_date,100) as end_time,

    cast (((BS.backup_size / 1024) /1024) as decimal(16,2)) AS MB

    frombackupset BS(nolock) JOIN backupfile BF(nolock)

    onBS.backup_set_id = BF.backup_set_id

    where backup_start_date > (SELECT MAX(backup_start_date) FROM backupset) - 1

    order by database_name, backup_start_date

  • Its caused by your join to the backupfile table, which is sending you 1 row for every database file (mdf) and 1 row for every transaction log file (ldf), instead of backup files.  Try just removing the join and see if you get what you're looking for.

  • Thanks, that worked! I was using the Backupfile table earlier but I no longer need it.
