SQL Server indexes – series intro

June 29, 2018 by

Description

In this series, we will dive deeply in the SQL Server Indexing field, starting from the surface by understanding the internal structure of the SQL Server tables and indexes, going deeper by describing the guidelines and best practices that we can follow to design the most efficient index and what operations can be performed on the created indexes. Having these knowledges about the SQL Server indexes, we have all the tools that help us in testing the lower part of the ocean and dive deeper with the two main types of the SQL Server Indexes; the Clustered and Non-Clustered, and the other types of indexes that can be customized to serve us improving your environment. After that, the adventure becomes more interesting when learning how to use this knowledge to tune the performance of our queries and touch the bottom of the ocean. In our way back to the surface, and before celebrating our achievements, we will collect statistical information about these indexes and use this information to maintain the indexes to take benefits from it continuously and gain the best application performance.

SQL Server Database Backup and Restore reports

June 14, 2018 by

In the previous articles, we discussed several ways of taking backup and testing the restore process to ensure the integrity of the backup file.

In this article, we’re going to discuss the importance of the database backup reporting. This kind of reporting will be designed to eliminate any unnecessary risk that may arise with the safety and security of information. This is the reason, the high-level report; Daily Health Check report will be generated and sent to the SME or to the DBA responsible for IT Infra management.

SQL Server Database Backup and Restore operations using the Cloud

May 29, 2018 by

This article discusses the concept of SQL Server backup and the various components required to use the Microsoft Azure Blob storage service as a target for the backup. As we all know, disk and tapes were the default destinations of choice until the evolution of the cloud platform. In addition to this, now we can expand the native functionality of SQL Server backup to cloud storage; the Windows Azure Blob storage. This functionality was added first in SQL Server 2012. In general, backup and restore functionality to and from the cloud are similar to using disk or tape, with very few differences.

How to perform a page level restore in SQL Server

May 18, 2018 by

In this article in our stairway series on SQL Server backup and restore, we shall discuss the importance of understanding the internals of the page restoration for a database administrator. Most of the time, performing a page-level restore suffices for database availability. A good backup strategy is a key to recovery or restoration, and SQL Server provides us with an option to fix database pages at a granular level. Performing a page level restore in SQL Server is a clever option wherein the restoration of the entire VLDB database backup is not required.

  2. Discuss the enhancements made in the Dynamic Management View (DMV) sys.dm_db_file_space_usage for smart differential backups
  3. Discuss the enhancements made for the Dynamic Management function (DMF) sys.dm_db_log_stats  for smart transactional log backup
  4. Understand the functioning of smart differential backup and its internals
  5. Understand the Smart transaction log backup process and its internals
  6. T-SQL scripts
  7. And more…

SqlPackage.exe – Automate SQL Server Database Restoration using bacpac with PowerShell or Batch techniques

May 7, 2018 by

Data is the key to your organization’s future, but if it’s outdated, irrelevant, or hidden then it’s no good. Maintenance and administration of databases takes a lot of work. As database administrators, we often tend to automate most of these repetitive tasks. A database refresh is one of the most common tasks performed by most of the administrators as part of their daily routine.

Today, database refreshes are quite frequent because of Continuous Integration (CI) and Continuous Deployment (CD). In most of the cases, testing requires a separate but current production dataset to ensure the validity of the desired result.

Understanding Database snapshots vs Database backups in SQL Server

May 4, 2018 by

In the article, we’ll walk through the concepts to understand database snapshots, and their benefits and limitations. This article will help you decide when to use a database snapshot, and when to use a backup. In some cases, the database relying on database backup and restoration operation is not a viable option. Let’s dig into the concepts of database snapshots and see how it differs from a database backup.

Discussing Backup and Restore Automation using SQLCMD and SQL Server agent

May 3, 2018 by

Database administrators are often requested to refresh a database, mostly to create a live copy of the production database to the test or development environment. This is done so that the development or the test environment closely resembles the production environment; this way, we prevent many undesirable issues when running the application in the production environment.

Many developers, at times, are required to write and debug code on the production copy of the database, so it makes more sense to refresh the database on regular basis.

Backup and Restore (or Recovery) strategies for SQL Server database

April 26, 2018 by

One of the most important roles of a database administrator is to constantly protect the integrity of the databases and maintain the ability to recover quickly in case of a failure. In light of this, it’s critically important to have a backup-and-recovery strategy in place in order to be ready for an emergency.

A key responsibility of a database administrator is to ensure that a database is available whenever it’s needed, and prepare for various scenarios wherein the availability or the performance is impacted. Therefore, if a database, for whatever reason, gets corrupted, gets dropped, gets accidentally deleted, or goes into an unusable state, it is a database administrator’s responsibility to bring the database back up in a working state with little to no loss as per the defined service level agreements or government policies.

Understanding SQL Server Backup Types

April 19, 2018 by

SQL Server backups, in itself, is a vast subject; so vast, there are multiple books written about them. In this article, however, we are going to focus on the types of backups that are available to us, and understand how to pick what we need, and what aspects we base that decision on. This understanding would, in turn, help us decide our backup-and-restore strategy.

Following are the most common types of backups available in SQL Server:

  1. Full
  2. Differential
  3. Transaction log
  4. Tail Log backup

Understanding SQL Server database recovery models

April 10, 2018 by

A recovery model is a database configuration option that determines the type of backup that one could perform, and provides the ability to restore the data or recover it from a failure.

The recovery model decides how the transaction log of a database should be maintained and protects the data changes in a specific sequence, which may later be used for a database restore operation.
