SQL Server Best Practices

Keep Your Database In Top Performance Shape and Maintain Effective Backups

September, 2007

Richard Kokoski


Abstract

Learn to keep your SQL 2000 and/or SQL 2005 database optimized with Reindexing. You’ll learn how do Reindexing, update statistics (for optimized queries) and “shrink” the database to eliminate unused or deleted data. Also learn how to create scheduled backup routines that include notifications (e-mail and paging) so SQL administrators know that their database is properly backed up. If you’re a SQL administrator (stakeholder) or a technical administrator (network and database), you’ll gain great insight and learn best practices necessary for effective disaster prevention and recovery.

Topics of Discussion

Backup Database•Backup Types•Scheduling•Notifications

Optimize Database• Database Integrity Checks

• Rebuild/Reorganize Indexes

• Update Statistics

• “Shrinking”


• Full Backup

• Complete Backup of Database at Point in Time

• Definitive Restore Point

• Easy Copy of Database to Separate Server

• Most Common for Smaller Size Databases

• Lost Data Minimized to Last Full Backup

Backup Database – Backup Types


• Differential Backup

• Backup of Database Data Since Last Full Backup

• Full Backup + Differential Backup Restores to Point in Time

• Faster & Smaller Backup than Full Backup

• Most Common for Larger Size Databases

• Lost Data Minimized to Last Full + Differential Backup

Backup Database- Backup Types


• Transaction Log Backup

• Backup of Database Data Since Last Transaction Log Backup

• Full Backup + Transaction Log “Rolling Forward” Restore to Point in Time

• Faster & Smaller Backup than Full Backup and/or Differential Backup

• Most Common for Databases Needing “Real Time” Backups

• Lost Data Minimized to Last Full + Series of Transaction Log Backups

Backup Database- Backup Types


• Full & Differential Backups

• Usually Scheduled Every Night

• SQL Backup Files Part of Overall Network Backup

• Ability to “Ad-Hoc” vs. Schedule


• May Loose Some Data Because of Scheduling

Backup Database- Scheduling


• Transaction Log Backups

• Usually Scheduled More Often then Every Night

• Made for “Real Time”


• Best Used to Reduce Lost Data Because of More Frequent Scheduling

Backup Database- Scheduling


Backup Database- Notifications

• Notification Types• Email

• “Net Send”

• Pager

• What to Send• Text Messages

• Customized Notes & Logs

• Operators• Usually Network and/or SQL Server Administrators

• Multiple Operators May be Defined


• Database Integrity Checks

• Overall “Health” of your database

• Consistency Checks of Data and Indexes

• Structurally and Physically Sound

• Identify Possibly Corruption Issues

• Advance Warning in Order to Fix

• Attempt to Correct “Minor” Issues (Single User Mode)

Optimize Database



Optimize Database

•What are Indexes?• Descriptors to Data in Tables & Views

•How Are/Who Uses Indexes• Querying Database

• Stored Procedures/Query Plans

•Why Rebuild Indexes• Corruption Issues

• Speed Enhancements

• Adjust “Free Space per Page” to Optimize Data Inserts



Optimize Database

•What are Statistics?• Information & Distribution of Data for Table/View Indexes

•How Are/Who Uses Statistics?• Query Planning/SQL Server Query Optimizer

•Why Update Statistics?• Auto Update vs. Manual Update

• SPEED - Overall Benefit of Faster Querying for the Database

• Let’s SQL Optimizer Make Better Judgments About Data Access


• “Shrinking”

Optimize Database

•What is “Shrinking”?• Free Wasted Disk Space in Database of “Inactive” Data

• Reduce Disk Space for SQL Log Files As well (After Truncate)

•Why “Shrink” The Database?• Improved Database Performance

• Eliminate Unnecessary Disk Space/Backup Space

• Improve Backup Times

• *Note: Shrinking Only Reads To Be Done When A lot of Data Is Purged
