Introduction
SQL Server has a reputation as being a simple database application to install, configure, and
maintain. This is a little misleading. SQL Server is a powerful relational database that can
handle the needs of the largest organizations and, as such, its proper maintenance almost
certainly requires the attention of an experienced DBA.
This reputation, coupled with the fact that it is relatively inexpensive, means that SQL
Server has become a favorite platform for multiuser applications, and it often appears in
organizations who cannot afford to have experienced DBAs on their staff. In many cases,
organizations have SQL Server instances that are maintained by a part-time DBA, or an
"accidental DBA," who may be a network administrator, developer, accountant, or even an

oce clerk. In the worst cases, nobody is looking after the health of the SQL Servers.
Millions of SQL Server instances run in the oces of small and medium-sized organizations,
more than the total number of instances that run in large organizations, and so it follows
that there are many accidental DBAs out there, who often don't have the knowledge, the
experience, or the time to perform the appropriate level of maintenance on their SQL
Server databases, much as they might like to. This can mean poor performance and
reduced availability.
Although not a perfect solution to this problem, SQL Server does offer two closely-related
tools that make it easier for part-time, non-professional DBAs to perform at least the
"required minimum" level of maintenance on their SQL Server instances.
These two tools are:
• Maintenance Plan Wizard – a Wizard that steps the user through the process of setting
up basic Maintenance Plans, with limited options.
• Maintenance Plan Designer – a drag-and-drop GUI interface in SSMS that facilitates
the design and creation of more flexible, customizable maintenance plans.
Unfortunately, neither tool is especially easy to use or well documented. However, with
the guidance I hope to provide in this book, they can become powerful tools in helping the
"accidental DBA" to perform critical maintenance tasks, and so help to ensure SQL Server's
performance and availability. In addition to learning how to use these tools you will, along
the way, pick up a lot of good, general advice on SQL Server database maintenance.

Who Should Read this Book
This book is targeted at the following groups of DBAs.
• Accidental/involuntary DBAs, who fell into the role of DBA "by accident" and who don't
have a strong background in database administration.
• Part-time DBAs, whose DBAs tasks are only a small part of their regular job duties, and
whose DBA skills range from novice to intermediate.
• Full-time DBAs, who are at the novice to intermediate level in terms of their knowledge
and experience.
If you fall into one or more of the above categories, then this book is for you, as it will not

only explain what database maintenance needs to be done, but how to do it properly using
the Maintenance Plan Wizard and/or the Maintenance Plan Designer.
More generally, I would suggest that these tools are most suitable for DBAs who:
• are not T-SQL or PowerShell experts, but who are able to get around in SQL Server
Management Studio (SSMS)
• typically have 25 or fewer SQL Server instances to manage
• typically have databases that are less than 100 GB
• are probably using the Standard Edition of SQL Server
• have an available maintenance window on a daily or weekly basis (24/7 uptime is
not a requirement).
If, on the other hand, you are an experienced DBA, managing many SQL Server instances, or
very large databases, or lots of simultaneous users, or needing 24/7 uptime, then these tools
are probably not, in general, suitable for your requirements. In fact, you're probably already
using custom T-SQL or PowerShell scripts to perform your database maintenance.
Having said this, although they are sometimes reluctant to admit it, I know many
experienced DBAs who still use the Maintenance Plan Wizard and/or the Maintenance Plan
Designer from time to time. Alongside their "mission critical" systems, even experienced
DBAs still maintain the databases of smaller, less active SQL Server instances and, for
this purpose, these tools are the quickest and easiest way to create and schedule the set of
maintenance tasks that will help ensure the continued smooth running of these systems.
