How to backup multiple SQL Server databases automatically

In situations with few databases, maintaining the regular backup routine can be achieved easily, either with the help of a few simple scripts, or by configuring a SQL Server agent job that will perform the backup automatically. However, if there are hundreds of databases to manage, backing up each database manually can prove to be quite time-consuming task. In this case, it would be useful to create a solution that would back up all, or multiple selected SQL Server databases automatically, on the regular basis. Furthermore, the solution must not impact the server performance, or cause any downtime.

How to create and manage database backup chains in SQL Server

Each event that causes data loss or disruption of regular daily operations on a SQL Server can be defined as a “disastrous” event. These events include power outages, hardware failure, virus attacks, various types of file corruption, human error, natural disasters, etc. Although there are many methods that are focused on preventing these events, they still occur from time to time, and therefore require proper measures to be addressed. One of the most effective methods for this purpose is the creation of suitable disaster recovery plan.

Two ways to rename SQL Server database objects

From time to time, a database object may need to be renamed for various reasons. When that happens, native features for renaming SQL Server database objects can be very useful. But, there are big differences between just renaming SQL Server database objects in the SQL Server Management Studio and Safe renaming them with ApexSQL Refactor.

This article will explain the differences between renaming database objects with SSMS and the ApexSQL Refactor’s Safe rename feature.

How to automatically compare and synchronize multiple databases on different SQL Server instances

Challenge

It’s often quite a challenge to keep all SQL databases located on different SQL Servers in sync. As time goes by, a lot of schema and data changes are made on QA databases on daily basis that require to be in sync with Production databases.

To keep everything in sync, there should a system that would be either triggered or scheduled to run the comparison of all SQL databases and synchronize the ones were changes are detected. This system should be also aware of any dependencies during the synchronization in order to keep the SQL database integrity.

How to set up email notifications for backup jobs in SQL Server

Introduction

For a SQL Server DBA handling multiple databases on any given time, knowing how to set up regular backup schedules, backups with unique names on a daily basis, making backup mirrors for redundancy, cleaning up old backup files is important. Equally important is automatic confirmation that the backups have been successfully created for the databases with an email notification. There are a couple of different ways to set up email notifications which can be done from Microsoft’s SQL Server Management Studio, or from a third party application for managing MS SQL Server backups like ApexSQL Backup.

How to detect whether index fragmentation affects SQL Server performance 

Background

After initial index creation in a SQL Server database, everything is properly ordered, which means that the logical index page order perfectly matches the physical index page order within the datafile. This is the ideal scenario and it allows for maximum query performance. If the table contains data that never changes, the index will remain perfectly ordered.

How to automate SQL Server defragmentation using policies

Introduction

Apart from numerous factors, poor index maintenance can be a reason for decreased SQL Server performance. If a database contains tables with numerous entries, that get updated frequently, it is most likely that high index fragmentation will occur. For smaller indexes, high fragmentation does not necessarily degrade the performance of the queries that are run on a table. But for the larger tables, with indexes that consist of 1000 pages and more, fragmentation could cause noticeable performance issues. Luckily, performing index maintenance tasks on a regular basis can eliminate the risk of degrading performance significantly. The most effective ways for treating index fragmentation are reorganize and rebuild index operations.

How to detect a high level of SQL Server database index fragmentation and fix it automatically

Introduction

When working with databases, availability and performance are of paramount importance. Performance of a database is based on multiple factors, key among them is being able to process queries quickly. That can be facilitated using indexes. Indexes are like the table of contents in a book, providing shortcuts to where the information is located. Otherwise, you would have to start reading the book from start until you find the information neededIt’s the same with databases, if it weren’t for indexes, for every query there would need to be an entire table scan.

Three phased approaches to getting your SQL Server database into source control

Challenge

Database development teams show an increasing interest in getting their SQL Server databases into source control. However, depending on the team’s actual needs, their development plan and the level of source control integration required, there are various ways to achieve getting a database under source control.

How to delete old database backup files automatically in SQL Server

Introduction

While working with a number of databases, creating a recovery plan can be challenging, especially if we want a foolproof design. Automated backup and restore strategies ensures the recovery plan is successful. However, strategies relying on frequent backups, although part of a sound strategy, can start causing issues when available storage space becomes limited. Old database backups are in many cases unnecessary, and it is often prudent to delete those backups to increase available storage. This can be done manually or automatically. There are several options to delete old backup files automatically in SQL Server:
