Why Backup is important
 Audits
 Disasters
 Is HA setup a backup ?
 Is LVM a backup ?

Types of Backup and Tools for these types
 Logical
– Mysqldump
– Mysqldbexport/import
 Physical
– MySQL Enterprise Backup (MEB)

8. Copyright © 2013, Oracle and/or its affiliates. All rights reserved.8
Logical Backup
 Advantages
– Easy of use - simple commands allow you to easily backup and restore
– Good for small database or tables – minimum impact on backup and
restore performance
– Flexibility – logical backup allows you to choose what you want to backup
and not backup. Change the scripts to restore partially etc.
– Readability - Good assurance that database files are not corrupt - all the
data is read and it is read using standard SQL queries.
Collection of SQL Queries to recreate the database

9. Copyright © 2013, Oracle and/or its affiliates. All rights reserved.9
Logical Backup
 Disadvantages
– Not an online solution - write operations are locked while performing the
backup, thereby blocking use of the database.
– Poor performance for larger databases – backup and especially restore
times are very slow for larger databases.
– No incremental backup – all backups are full backups, can be time
consuming and require more storage.

Physical Backup (MEB)
 Advantages
– Performance –faster for backups and faster for restore
– Flexible – support for incremental backups, partial backups, backup
compression, point in time recovery and more.
– Archival Backups – suitable archival format for historical purposes
– Scalable – performance is near linear for larger databases.
– Consistent – delivers consistent point in time recovery

MEB Backup
 Full Backup
 Incremental Backup – File based
and Redo log only
 Compressed Backup
 Backup to Single File/Image
 Backup to tape
 Partial Backup
What is methods are available to choose from

15. Copyright © 2013, Oracle and/or its affiliates. All rights reserved.15
MEB – Apply log
 InnoDB consists of pages with
information about the LSN
number applicable to the page
 Applylog scans the InnoDB redo
log and applies the relavant
changes to the InnoDB page and
upto the correct LSN to be
applied
The intermediate step

16. Copyright © 2013, Oracle and/or its affiliates. All rights reserved.16
MEB – Recovery
 copyback,
 copyback-and-apply-log*
 Validate
Recovery is what is important

What’s New in MEB 3.9
 New! Single Step
– Restore directly.
 New! Selective
– Leverages TTS
– Great for large tables
 New! Skip Unused Pages
– Reduces space
 New! Full Instance
– Config/Settings/…
 Continuous progress
– %, Bytes, Status
 Monitor disk space
– Optional action : Warn & Retry, Abort,
Remove

22. Copyright © 2013, Oracle and/or its affiliates. All rights reserved.22
Single Step Restore
 You don't have to store the intermediate contents anywhere
 Pipe backup stream directly to remote machine
 Optionally, perform compression /decompression on the fly
 Optionally perform restore operation simultaneously
Easy to create a slave
mysqlbackup --user=root --port=3306 --backup-dir=backup --socket=/tmp/mysql.sock
--backup-image=- backup-to-image | ssh <user name>@<remote host name> ‘
mysqlbackup --backup-dir=backup_img --datadir=/data/datadir
--innodb_log_group_home_dir=. --innodb_log_files_in_group=8 --innodb_log_file_size=5242880
--innodb_data_file_path="ibdata1:12M:autoextend" --backup-image=- copy-back-and-apply-log'

23. Copyright © 2013, Oracle and/or its affiliates. All rights reserved.23
Selective backup with TTS
 MySQL 5.6 feature : Transportable
Table spaces
– Online table portability :
Import/Export
 Why use with MEB
– Locking time
– Ease of use
What is TTS, why better than normal partial backup

24. Copyright © 2013, Oracle and/or its affiliates. All rights reserved.24
Skip Unused pages
 InnoDB files don’t shrink
 A small DB has many unused pages
 There is a performance penalty
Cleaning up before a backup
