Hi,

Ive been trying to figure out a way, to query the backup info for my Azure SQL databases, without having to login to the Azure portal.

I came up with the query, and at first it looked like it worked as expected:

select *
from
    (SELECT Name,
        Database_ID,
        physical_database_name
    from sys.databases
    WHERE database_id > = 4
    ) as databaseinfo
    LEFT JOIN (
    select
        physical_database_name,
        backup_file_id,
        backup_start_date,
        backup_finish_date,
        case backup_type
        WHEN 'D' THEN 'Full'
        WHEN 'I' THEN 'Differential'
        WHEN 'L' THEN 'Transaction log'
        END AS BackupType,

        CASE in_retention 
        WHEN 1 THEN 'In retention'
        WHEN 0 THEN 'Out of retention'
        END AS IsBackupAvailable
    from sys.dm_database_backups
) as backupinfo
    ON backupinfo.physical_database_name = databaseinfo.physical_database_name

But it appears that the databases, have the same value in physisal_database_name, which makes no sense in my opinion.

UniqueDatabaseName

How do i query my backup AND join it with the other tables, so that i can see the database name?

What you're seeing there is the internal server name. It's not actually a database, but the VM on which your databases are running. I don't have all the internals access to get into details beyond what I just typed though.

I'm not sure how to get the database name. Maybe through the database_guid there. I'm not sure if that maps back to sys.databases or not.

I was afraid, that it would be the answer.

I cant seem to find a way, to map the database_guid to the info from the sys.dm_database_backups table - if you have more suggestions, im all ears 🙂

I don't have an answer or even a guess. Hang on though. I'll see if I can get some help.
