Running and maintaining multiple SQL Server instances can often be a formidable challenge, especially if these instances run on multiple servers. It is easy enough to set up a SQL Server agent job for each server to automate the backups, but what happens if there are 20, 30, or 100 servers that need maintenance? In this scenario, configuring agents on each server would take forever, and monitoring the entire setup would prove to be a nightmare for any administrator. Of course, there are several solutions for this scenario:

What is a piecemeal restore?
A piecemeal restores allow the user to restore only a specific filegroups from a database instead of restoring a whole database. In cases of emergency the important thing is to get the needed data as quickly as possible, and restore the rest of the data later while having the most significant data online. This approach minimizes the downtime when a disaster occurs.

From time to time, DBAs find themselves in a situation where a SQL Server database becomes too large for their production environment, and needs to be shrunk in size in order to free space and allocate it back to the system.
Before shrinking a SQL Server database or database files, it is very important to understand how the process works and what are the immediate consequences of the shrinking process.

The purpose of SQL Server index is pretty much the same as in its distant relative – the book index – it allows you to get to the information quickly, but instead of navigating through the book, it indexes a SQL Server database.

In the first part of the series, we’ve showed how to perform a point in time restore using SQL Server Management Studio and ApexSQL Log. In the second part of the article, we’re going to introduce two more solutions – performing a virtual restore (in time) with ApexSQL Restore, and performing a full point in time restore with ApexSQL Backup.

This article explains how to create filegroups and move indexes into a different file group, and how to backup a database without indexes with the purpose to reduce the amount of data required to perform backups thus reducing backup time and space required. We will also show how to use the ApexSQL Backup solution for filegroups backup as a first part of the series in which we will show how to backup and restore a database without indexes, and to recreate the indexes after a restore.

Why running DBCC CHECKDB?
DBCC CHECKDB checks the logical and physical integrity of all the objects in a database and provides information of any corruption.
As performing DBCC CHECKDB is a resource exhaustive task it is recommended to run it on a production server when there is as less traffic as possible, or even better, as one of the ways to speed up the DBCC CHECKDB process, is to transfer the work to a different server by automating a process and run CHECKDB after a database restore. As a backup process is a copy of a database and a restored database will be exactly the same as an online database therefore if there were any inconsistencies or issues they will be in the backup, and found in a restore. By using this approach both restores will be tested and backups verified without any impact on a production database.

SQL Server stores a complete history of all SQL backup and restore operations, and other historical activities such as activities like Database Mail, Jobs, Log Shipping, Policies, Maintenance Plans, etc. on a server instance in the msdb database.

One of the most common ways to ensure that the recovery will be possible if a data-file corruption or any other disaster occurs is to create a recovery plans for this scenario. The most popular recovery plans include regular creation of database backups which can later be used to restore a database to a nearest available point in time, prior to disaster.
In order to create and apply successful recovery plan, it is important to create a solid backup schedule and to manage backups of multiple databases across different SQL Server instances.
In this article we will create a SQL Server scheduled backup by using a SQL Server Agent job and ApexSQL Backup.

When recovering from a SQL Server database failure, a database administrator needs to restore a set of SQL Server database backups in a logically correct and meaningful restore sequence. With this in mind, to the goal is to devise a disaster recovery strategy by creating a solid backup plan, as well as a proper database restore plan in SQL Server. This article will describe 2 different solutions for creating and scheduling a database restore in SQL Server.
