Read more »This article is dedicated to creating custom differential and Transaction log backups so that you will see sufficient data in the file size. In SQL Server there are mainly three backup types, Full Backup, Differential Backup, and Transactional Log backups. A Full backup will get the entire database into a backup.
Read more »I have dedicated this article to the topic of Elastic Jobs in Azure SQL Database which is in Public Review. This feature allows you to run scheduled tasks in your Azure SQL Databases. This is similar to SQL Server Agent you have in the On-prem SQL Server versions. However, in Elastic Jobs, you can execute the scheduled tasks in multiple Azure SQL Servers and multiple Databases which is an added advantage when considering the features of SQL Server Agent. Further, this execution performs parallelly.
Read more »In this article, we will be looking at how to perform and access Dynamic Data Masking in SQL Server. Data Masking is the process of hiding data with different rules. One of the main reasons to apply data masking is to protect Personal Identifiable Information (PII) and sensitive data from unauthorized access. Even when unauthorized users access these data, they will not be able to view the actual values. This article will look at the possibilities of applying Dynamic Data Masking in SQL Server and we will look at how Dynamic Data masking can be applied to the Azure SQL Databases as well.
