These backups can be used for point-in-time recovery, or to restore databases to another Azure location or region, or you need to restore this database from a very old backup that is kept under a long-term retention policy.īackup storage redundancy is also supported for automatic backups. The system will decide when to run which backup and their schedules based on the workload on your database. The remaining differential and transaction log backup will start running after this full backup in the background. Azure does it on your behalf whenever you deploy any SQL database. You don’t need to configure anything for that. The first full backup will be taken by Azure as soon as you deploy your Azure SQL database. Transaction log backup captures log details in the incremental format so if you have missed any previous log backup then you cannot recover your database beyond that log backup.Īutomatic backups for these databases run one full backup weekly, differential backup on every 12 to 24 hours interval, and transaction log backup on every 5 to 10 minutes. It is also used for point-in-time recovery. Differential backup captures only those changes which were done since the last full backup and Transaction log backup captures the log records from the transaction log file. The full backup is a complete dump of your database including everything present in the database and transaction log file. It also reduces administration complexities and the efforts DBAs spent on managing database backups.Īzure SQL database supports 3 types of backups like SQL Server to achieve a point in time recovery. ![]() This article will explain Azure SQL database backups to help you understand how backups work for these databases in the background and how can we use them for our data protection and recovery requirements.īackups are managed internally by Azure for their PaaS database products like SQL database or Azure SQL managed We generally use this deployment for modern cloud-compatible applications or if we want to leverage hyperscale or serverless options. This database service offers rich functionalities to increase the availability with the help of in-built high availability capability and reduce the manageability efforts by using easy and smooth deployments, automatic backup, and patching, etc. It is a fully managed SQL Server database engine that uses the latest stable version of SQL Server enterprise edition. Once you're familiar with the basics, you'll move on to next level that explains the methods of retrieving records through joining multiple tables, searching records in the table based on pattern, etc.įinally, you'll explore some advanced concepts, such as modifying the existing table structure, performing aggregations and grouping data together, creating views to simplify and secure table access, creating indexes for tables, handling dates and times, cloning of an existing table, creating temporary tables, as well as, concept of SQL subqueries and SQL injection.Azure SQL database is Database as a Service offering under the PaaS model in the Azure cloud. This SQL tutorial series covers all the fundamental concepts of SQL language, such as creating database and tables, using constraints, adding records to a table, selecting records from a table based on different conditions, updating and deleting records in a table, and so on. Note: Most of relational database systems also have their own additional proprietary extensions in addition to the SQL standard that are available only on their system.
