What Do We Protect Data From?
• Server Failure
– Hard Drives Stop Spinning, Storage Controllers Corrupt Data, etc
• Accidental Drop or Delete
– The “Arggg Sh***!” factor
• Security Compromise
– Server, Database, Application
• Business or Government Regulation
– Historical Archiving Rules – HIPPA, EU Data Archiving Regulations
Who Protects Data MySQL?
• Different Users Have Different Needs and Preferences for Data Protection • Three Types of MySQL Administrators 1. Developers 2. Accidental Admin 3. Database Administration (DBA) Guru
MySQL Developers
• Some develop on test systems MySQL Data Protection Not Important • In Practice Development often on live production environments! Oh My! • Hidden Risk for Stakeholders • Single copy of PHP / Python / Perl Scripts Often Located on Server
PHP, Perl and Python used by ~85% of MySQL Developers
Accidental MySQL Admin
• Accidental MySQL Admin
– Who Are They? • Proprietor of Web 2.0 Business • Hosting Business • Network or System Administrators • The Small Office PC Technician – Simple is Better – Binary Log, Clustering and Replication techniques often out of reach or unused
MySQL DBA Guru
• MySQL DBA Guru
– Often using Clusters and Replication – Likes to performance tune and understand all details – Custom data protection scripts and methods prevalent – If a professional serving many clients simple data protection solutions desired
MySQL Data Protection Ideas
• • • • RAID Replication Clusters MySQL Backup and Restore
RAID
• RAID Attributes
– Software or Hardware RAID – Available on Windows, Linux, Unix – Some RAID levels protect against drive failure
• Good Data Protection?
Archiving Accidental Drop or Delete Server Failure Security Compromise None Data Loss! Data May Be Lost! All Data Compromised!
Replication
• One Writer and Many Readers
– – – – MySQL Master Slave Replication Some Protection against server failure Multiple copies of data Replicates accidental data deletion!
• Good Data Protection?
Archiving Accidental Drop or Delete Server Failure Security Compromise None Data Loss! Protected Limited Protection
Clusters
• Many Writers and Many Readers
– – – – – Usually Linux / Unix Only Examples: DRBD, NDB, Continuent Protection against server failure Multiple copies of data Replicates accidental data deletion!

Archiving Accidental Drop or Delete Server Failure Security Compromise Data Loss! Protected Limited Protection
Evaluating MySQL Backups
• Archive Management?
– Does application easily manage historical archives
• Archive Type?
– People either need disk or tape or both
• Supported Environment
– What storage engines are supported? – What O/S’s are supported?
• Binlog Restore
– Rollback to selected transaction using binary log
• Zero Business Interruption (Hot Backup) • Granular Restore
Evaluating MySQL Backups Continued
– means no noticeable interruptions to connections or queries on live database system – Means restore selected Databases or Tables to original or alternate locations – Who Needs it Most?: Developers, DBA Guru
• Ease of Use
– Graphical User Interface, Web Interface, etc – Who Needs it Most?: Developers, Accidental Admin
• Complete Server Protection
– Does it just protect MySQL? Or Server Also?
• Backup Type
Evaluating MySQL Backups Continued 2
– Full • All data transmitted and stored every backup – Incremental • Complex combination of periodic full, and more frequent incremental backups – Virtual Full Backups • One full backup, with deltas sent from then on. Each backup appears as full backup, only deltas sent across network and stored.
• Backup Window
– How long is the backup Window on Large Data Sets?
• Server I/O and Load Impact
– Does it kill the server when data set is large?
• Financial and Banking
– Binlog Restore Critical – Tape Backup – Example:
What Are Your Data Protection Priorities?
• Typical Embedded OEM Network Device
– Usually small databases – Proprietary device/app. Management handles backups using mysqldump or mysqlhotcopy – Exceptions are carrier grade clusters – Example:
• Massive Transactional Enterprise System
– – – – Master data located on mainframe or Unix not MySQL Data replicated for read-only queries to MySQL Use existing mainframe or Unix backup system for data protection Example:
• Web 2.0 / LAMP Stack Application / Web Hosting
– – – – – – – Zero Business Interruption (Hot Backup) Critical Granular Restore for developers Ease to Use GUI Complete Server Protection Short backup window with minimal server impact Disk Based Backup Dominates Large Databases
What Are Your Data Protection Priorities?
– Examples:
MySQL Backup Applications
• Legacy Backup
– – – – – – The Dump Binary Log Backups mysqlhotcopy Volume Snapshot Hot Backup InnoBase (Oracle) Backup Replication Slave Backup
• Legacy Backup with GUI
– ZRM, Bakbone, and others
• Alpha MySQL Online Backup API • near-Continuous Data Protection

Volume Snapshot Hot Backup
• Uses snapshot capability of volume manager on Linux (LVM) or Unix: Veritas VxFS, NetApp SnapManager • Linux: uses LVM snapshots • Usually implemented with custom scripts or programming by a DBA
5.Lock Tables in MySQL 6.Take Volume Snapshot 7.Unlock Tables in MySQL 8.Copy Raw Tables from Snapshot

Slaves Are Hard Workers
• MySQL Replication Slave for Backup • Replication Can be Paused on Slave to Allow Point-intime backups • Long backup operations can proceed without disrupting other servers • Backup Disk I/O isolated away from customer facing servers

Big $$ for User Interfaces?
• Most Commercial Software Vendors make Expensive Wizards and User Interfaces for MySQL Backup • What Do You Really Get? Is it worth your $$?
What is Under The Hood?
• Answer: Little more than mysqldump, mysqlhotcopy, binlog !

Alpha MySQL Online Backup API
• Commercial vendors told MySQL AB: build as an API and we’ll build hot backup apps! http://forge.mysql.com/wiki/OnlineBackup
• Implemented and Not Yet Released (MySQL 6.0.5 )
– Online Backup without Interruptions for InnoDB and Falcon – SQL Interface for Initiating Backups • BACKUP DATABASE databasename1, databasename2 TO "filename.backup"; • RESTORE FROM "filename.backup";
• Limitations Still Being Worked Out
– – – – – Can’t backup replicated Databases No backup of database privileges No selective (table level) backup and restore No Compression No MyISAM support

Developer, Accidental Admin, DBA Guru Disk InnoDB and Falcon All Yes when used with binlog backups Yes (Only InnoDB and Falcon for now) No (No Table level restore) No No Full (incremental with binlog) Long Heavy
MySQL near-Continuous Data Protection
• Online Backups for MyISAM and InnoDB
– Similar to Linux LVM Backup Method except LVM not required! – All block devices supported! Software RAID (MD), MultiPath, ISCSI, Windows Dynamic Disks, etc – Low Level Volume Snapshots with Device Driver (Linux), Volume Shadow Copy (Windows)
• Scheduled Synchronizations
– E.g. Every 15 minutes, Hourly, Daily, etc.
• Changes to Disk Sectors Tracked in between Synchronizations = Short Backup Windows with Minimal Impact • Granular Restore to Table Level • Recovery Point Archiving
– Only Deltas Stored after first full backup – Each archive point appears as virtual full backup
