ReliaSoft's
Synthesis-enabled
applications, as well as earlier versions of Xfmea/RCM++ and
XFRACAS, can be deployed with a SQL Server database for centralized data
storage. With enterprise-wide, database-driven software applications
such as these, it is important to have established procedures to assure
that proper database maintenance and backup activities are being performed.
These activities are the responsibility of the organization that implements
the system (since ReliaSoft's support personnel do not have access to,
or specific knowledge of, the IT infrastructure used to deploy the system).
This document presents ReliaSoft's recommendations for the minimum
database backup and maintenance activities that should be performed
in SQL Server to protect the organization's data and keep the system
running smoothly.
Click the appropriate link to jump to the instructions for your version
of SQL Server. This document contains instructions for creating backups
in:
Note: To view the instructions for creating backups
in Oracle, see document number RS40006. To
view the instructions for creating backups in SQL Server Express, please
see RS40023.
ReliaSoft makes these two minimum recommendations for maintaining
SQL Server 2008 databases:
- Create a Database Maintenance Plan that creates a
Full backup within SQL Server.
- Create a Database Maintenance Plan that creates a
Transaction Log backup within SQL Server.

Create Transaction Log Backups Using a Database
Maintenance Plan within SQL Server 2008
Note: These instructions follow the same steps
as above, but because we suggest running transaction log backups throughout
the day (this may vary depending on your business needs), we suggest
creating a separate Maintenance Plan, which has a more frequent schedule
than once a day, for the transaction logs.
- Open the SQL Server Management Studio by choosing Start
> Programs > Microsoft SQL Server 2008 >
SQL Server Management Studio.
- Expand Management and right-click Maintenance Plans.
Choose Maintenance Plan Wizard.
- Click Next to proceed past the start page and to the
first step of the wizard. Type a descriptive name for your maintenance
plan (e.g., MaintenancePlan-Transaction_Log).
- Make sure Single schedule for the entire plan or no schedule
is selected. Click the Change button to open the Job Schedule
Properties window.
- Choose Recurring for the Schedule type and select
the Enabled check box. In the Frequency section, choose
Occurs Daily and Recurs every 1 day. In the Daily
frequency section, select Occurs every and choose 4 hours
and Starting at 12:00 AM (assuming that you have
followed the previous section's suggestion and set the full
backup to 2:00 AM -- to ensure it will not be running at the
same time as the full backup). Click OK.
- Click Next to proceed to the Select Maintenance Tasks
page.
- On the Select Maintenance Tasks page, choose Back Up Database
(Transaction Log). Click Next.
- On the Select Maintenance Task Order page click Next.
- On the Define Back Up Database (Transaction Log) Task page
click the down-arrow to the right of Databases and choose your
database from the list. Click OK to close the
database selection window. Choose the media for the backup (i.e.,
Disk or Tape) and the location for the backup. Select Verify
backup integrity. Click Next.
- On the Select Report Options page, you can choose to have the
maintenance plan generate reports. This is optional. Click Next.

ReliaSoft makes two minimum recommendations for maintaining SQL Server
2005 and earlier databases:
- Set the Recovery Model to Full.
- Create a Database Maintenance Plan that creates a
Full backup within SQL Server.
Note: The instructions in this section were prepared
using SQL Server 2000. The options may vary for SQL Server 7.0 or 2005.
Set the Recovery Model to Full within SQL Server
2005 and Earlier
- In the SQL Sever Enterprise Manager, right-click the
database and select Properties.
- Go to the Options page. Choose Full for the
Recovery Model, as shown next. Click OK.

Create a Database Maintenance Plan within
SQL Server 2005 and Earlier
- Launch the SQL Server Enterprise Manager and use the
hierarchy to navigate to your server. Under the server, expand the
folder called Management.
- Under Management, right-click Database Maintenance Plans
and select New Maintenance Plan to start the Database Maintenance
Plan Wizard.

- Click Next to proceed to the first page of the wizard.
When prompted to select the databases for which to create the maintenance
plan, ReliaSoft recommends choosing the application database, "master," "model" and "msdb," but only the application
database is required.
- Click Next to proceed to the next page of the wizard,
Update Data Optimization Information, as shown below.
- Select Reorganize data and index pages and Change
free space per page percentage to 10.
- Select Remove unused space from database files and
keep the default value of 50 MB.
- It is recommended to change the schedule to daily, to be
done after hours. Also, if your backup is to tape, it is recommended
to have this performed before that process. The time it takes
to complete the maintenance depends on the size of your database
and the hardware used to host the database.

- Click Next to proceed to the next page of the wizard,
Database Integrity Check, as shown below.
- At minimum, select Check database integrity and
Include indexes. Do not select Attempt to repair any
minor problems since the given database must be in single-user
mode to use this value.
- You may accept the schedule default value of once a week
or you may change the schedule.

- Click Next to proceed to the next page of the wizard,
Specify the Database Backup Plan, as shown below.
- Select the options to Back up the database as part of
the maintenance plan and Verify the integrity of the
backup when complete.
- Set the location to Disk.
- Schedule daily backups. If you have a system tape backup,
then schedule the database backup to occur before the system
tape backup.

- Click Next to proceed to the next page of the wizard,
Specify Backup Disk Directory, as shown below.
- You may use the default backup directory or specify your
location.
- If you specify the Create a subdirectory for each database
option, the system backs up each database into separate folders.
- Select the Remove files older than option, and specify
how long to retain previous backup files. Usually, removing
files older than two weeks will be adequate. Of course, this
depends on the database size, the amount of free space on the
system hosting the database and your organization's preferences.

- Click Next to proceed to the next page of the wizard,
Specify the Transaction Log Backup Plan, as shown below.
- Select the options to Back up the transaction log as
part of the maintenance plan and Verify the integrity
of the backup when complete.
- It is recommended to backup the transaction logs every 2
to 4 hours during normal business hours. Each environment is
different, so you should set these options based on the acceptable
amount of data loss in case of a failure.

- Click Next to proceed to the next page of the wizard,
Specify Transaction Log Backup Disk Directory, as shown below.
- It is recommended that you choose the same options as you
did for the database backup location.

- Click Next to proceed to the next page of the wizard,
Reports to Generate, as shown below.
- If you choose, you can have the maintenance plan generate
reports. This is optional.

- Click Next to proceed to the next page of the wizard,
Maintenance Plan History, as shown below.
- The default options are usually adequate. You can view the
history by right-clicking the Maintenance Plan under Database
Maintenance Plans under Management and selecting Maintenance
Plan History.

- Click Next to proceed to the final page of the wizard,
as shown below.
- Name your plan and click Finish.

Execution of the Maintenance Plan requires that the SQL Server Agent
be active. The system displays an error message if the SQL Server Agent
is not active. If necessary, activate the SQL Server Agent the same
way you activated SQL Server.
- To start this service, click the SQL Service Manager located
in your system tray by the clock.
- Select SQL Server Agent and start it. You will probably
want to select the Auto-start service when OS starts
check box also.
- After this, your maintenance plan should run as scheduled.
