How to Create Azure Database Recovery Model?

Azure Database Recovery Model is a database configuration option that defines the types of backups that can be performed and provides the ability to recover data from failures.

The recovery model determines how to maintain database transaction records and prevent data changes in a particular order. This change can be applied later for Azure database recovery operations.

Azure Database Recovery Model

Different Types of Azure Recovery Models

Backup, restore, and recovery operations for all Azure databases depend on one of three recovery models available:

  1. SIMPLE
  2. FULL
  3. BULK_Logged

Simple Azure Database Recovery Model

The SIMPLE azure recovery model is the simplest model available. Full backup, differential backup and file-level backup are supported and transaction log backups are not supported. The log space is reused each time a checkpoint is executed in a background process in Azure Server. The inactive portion of the log file is deleted and can be recycled.

Point-in-time and page restoration is not supported. Only read-only backup file recovery is supported.

Reasons to Select Simple Azure Database Recovery Model:

  1. Suitable for developing and testing databases.
  2. A simple report or application database that can tolerate data loss.
  3. A single point of failure recovery is for full and differential backups.
  4. No administrative costs.

Full Azure Database Recovery Model

In FULL recovery model all transactions DDL (Data Definition Language) + DML (Data Management Language) are fully recorded in the transaction log file. The save sequence is uninterrupted and is stored for database recovery operations. It’s not like a typical Azure recovery model. Transaction log files are not automatically truncated during CHECKPOINT operations.

All Azure database recovery operations are supported including restoring the interval page recovery and file recovery.

Reasons to Select Full Windows Azure Database Recovery Model:

  1. Support for mission-critical applications.
  2. Designing a high availability solution.
  3. To facilitate complete data recovery with zero or minimal data loss.
  4. If your database is designed to have multiple file groups and you want to restore a separate read/write secondary file group and an optional read-only file group.
  5. Allow point recovery at any time.
  6. Restore each page.
  7. High administrative expenses.

BULK_Logged Azure Database Recovery Model

This is a special purpose database configuration option and it works like a full recovery model. Except that certain bulk operations can be recorded to a minimum. Transaction log files use a technique known as a minimum log of bulk operations. The problem is that you can’t restore the data at any one time.

Reasons to Select BULK_Logged Azure Database Recovery Model:

  1. Uses minimal recording technology to prevent log file growth.
  2. When the database is subjected to a lot of routine operations.

Recover Azure SQL Database with All Objects

Author advice is to use SQL Server Recovery Software. There are many corruption errors that cannot be fixed manually. This professional solution can fix any problem related to the SQL Server database like SQL Server Object Level Recovery.

This software allows you to check the database before restoring it. In this way, you can selectively restore your data. You also have the option to restore deleted tables and all object such as triggers, views, indexes, sequences, forms, reports, etc. Also helps when Ransomware Attack on SQL Server happens.

Summing Up

The default recovery model for Azure databases is FULL and cannot be changed to other recovery models such as on-premises recovery models. The recovery model is set when the master database is created. This means that if an Azure Server is provisioned the master database will be read-only and you can’t change the recovery format.
