Azure SQL Managed Instance provides a default backup retention of 7 days and this cannot be changed as per MS. Access to the Automated backups are not provided as well which is quite surprising. My client requires the backups to be restored for their analysis.
Requirement is to have last 14 days daily back and 1st day of every month backup to be saved.
How can the above requirement is meet? or How do we create automated
backups and auto archiving from our end in MI with TDE on?
Provide the location where these automated backups are stored.
Managed Instance now supports up to 35 days of backup retention (instead of 7) see https://learn.microsoft.com/en-us/azure/sql-database/sql-database-managed-instance-index#new-and-preview-features
MI Supports 7-35 days backups retention depends on pricing tier. MI also supports long-term retention of full backups for up to 10 years in Azure blob storage. You can't get access to Azure automated backups but you can schedule copy_only backups on URL.
For TDE and other information you can check following link:
https://learn.microsoft.com/en-us/azure/sql-database/sql-database-automated-backups
Updated information (May 2020):
Managed Instance now supports 1-35 day PITR backup retention for active databases, and 0-35 days for deleted databases (0 would mean no backup is kept). More info here: https://aka.ms/mi-backup-tuning.
LTR support for Managed Instance is also available with up to 10 years of retention. More info here: https://learn.microsoft.com/en-us/azure/sql-database/sql-database-long-term-retention#managed-instance-support

Due to the requirements of ISO accreditation we need to setup notification logic when long term retention backup was taken in Azure SQL Server ( not SQL Server on Azure VM).
Does anyone have any ideas about how to accomplish this goal?
P.S we don’t want to move our DB to Azure VM, so we can’t use Backup Alert service or something like this that is related to SQL Server Azure VM deployment way.
There is no out-of-the-box method to achieve this. Shortest you can concentrate on is a week see.
Below are few points to consider.
You cannot control the LTR backup time, you can define a policy using a combination of four parameters: weekly backup retention (W), monthly backup retention (M), yearly backup retention (Y), and week of year (WeekOfYear) but not exact date and time.
Azure SQL database backups - responsibility to monitor and fix #11412
Possible workaround
Since LTR backups store full Database backups, this causes Metric Full backup storage size to update. You can monitor through custom charts and set alerts.
You can further leverage Azure Monitoring REST API
Im checking several tutorials about how to setup and configure a sql backup to blob, but what Ive found so far are to backup from Sql Server Management Studio.
I did found this nice article at azurelessons: https://azurelessons.com/backup-azure-sql-database/
But the problem I have is that they mention a "Manage Backups" option at the settings group (Sql server level) which I cannot seem to find:
And when I go to the Backups option on Data Management, it only shows me one that is 7 days old with the following legend: "Azure SQL databases are backed up automatically. Backup availability is listed below for each database on this server. Manage your available long-term retention (LTR) backups or restore a database here."
I have a failover group for the SQL server, but I would also like to have backups performed every 6 hours, and I just cant find the option where to do this, even on the SQL Database.
Thanks for the help.
It looks like you have a managed instance of SQL
Both SQL Database and SQL Managed Instance use SQL Server technology to create full backups every week, differential backups every 12-24 hours, and transaction log backups every 5 to 10 minutes. The frequency of transaction log backups is based on the compute size and the amount of database activity.
When you restore a database, the service determines which full, differential, and transaction log backups need to be restored.
Please check this link:
https://learn.microsoft.com/en-us/azure/azure-sql/database/automated-backups-overview?tabs=single-database
I am having an issue creating differential backups of Azure SQL database in storage account blob storage using powershell. I don't know if it is possible or not to get a differential back up of an Azure SQL database. Please suggest me what can I do.
If have seen the differential backup document, you will find this:
Azure SQL database has the feature Automated backups. It referred that:
SQL Database supports self-service for point-in-time restore (PITR) by automatically creating full backup, differential backups, and transaction log backups. Full database backups are created weekly, differential database backups are generally created every 12 hours, and transaction log backups are generally created every 5 - 10 minutes, with the frequency based on the compute size and amount of database activity. The first full backup is scheduled immediately after a database is created. It usually completes within 30 minutes, but it can take longer when the database is of a significant size. For example, the initial backup can take longer on a restored database or a database copy. After the first full backup, all further backups are scheduled automatically and managed silently in the background. The exact timing of all database backups is determined by the SQL Database service as it balances the overall system workload. You cannot change or disable the backup jobs.
I also asked Azure Support, they told me that we(customer) can not create the differential backup by ourselves, Azure SQL database will do that automatic.
Hope this helps.
I've configured the retention policy in 'Manage Backups' for my Azure SQL Server but nothing is appearing under 'Available Backups'. Does there need to be an associated storage account? If so, how do I set it up?
From Azure's doc it is known that the automatic backups (full, differential and transaction log) are possible. And it is possible to configure retention period for these backups. The main question is where these backups are stored (from documentation by default within RA-GRS Standard blob storage)? and whether it is possible to change storage account and how to access to standard storage account with backups?
Thanks in advance.
Automatic backups are part of Azure SQL Database service and are managed by Azure. You cannot change where these backups are stored, that is managed by Azure. You cannot access those backups and copy them to another storage account, and you cannot manage them.
You can use PowerShell Get-AzureRmSqlDatabaseRestorePoints to get the earliest possible restore point for the database based on the automated backup service.
Get-AzureRmSqlDatabaseRestorePoints -ResourceGroupName "resname" `
-ServerName "yourservername" -DatabaseName "yourDBName"
With automatic backups, full database backups are created weekly, differential database backups are generally created every 12 hours, and transaction log backups are generally created every 5 - 10 minutes, with the frequency based on the performance level and amount of database activity. The first full backup is scheduled immediately after a database is created. It usually completes within 30 minutes, but it can take longer when the database is of a significant size.
If you want to have control over backups, you want to have greater retention period, then you can configure long term backups o export bacpacs of your database to an storage account as explained here.
I have a question related to Azure SQL Databases.
I know that we can restore databases to any point in time (7 or 35 days) for different tiers in Azure. That is fine.
However, I am wondering how long the deleted Azure SQL databases will be available to restore for.
Does anybody know?
Any answer will be appreciated.
Deleted databases can be restored to the point in time of deletion during the retention period of the service tier they were in. (currently that is Basic: 7 days; Standard and Premium: 35 days 7 days).
For more information:
https://learn.microsoft.com/en-us/azure/sql-database/sql-database-business-continuity
https://learn.microsoft.com/en-us/azure/sql-database/sql-database-recovery-using-backups#deleted-database-restore
https://learn.microsoft.com/en-us/azure/sql-database/sql-database-automated-backups
Also, if you delete the SQL server that was hosting the databases, all the backups are GONE instantly.
Backups will be stored till retention period: Microsoft docs quote below(emphasis mine): and this is covered on Overview of business continuity with Azure SQL Database in Perform a point-in-time restore section
You can use the automated backups to recover a copy of your database to a known good point in time, provided that time is within the database retention period.
