Customer Facing Data (CFD)
• As important as CRM and Financial Data
– For many companies loss of CFD implies catastrophe
– Lost revenues, lost customers and lost reputation
• Today’s Data Protection Challenge
• Break neck rate of change
• MySQL is the database of choice for CFD
• Metadata is very vital as well

“Oops!”
“I forgot to add a
“where” clause and
emptied the entire
thing!”
“Hi, I lost MySQL
server and I didn’t
do backups. What
can I do?”
“… the server on which my
blog is being hosted was
being changed and for
some reason during the
importing the MySQL
databases disappeared ”
“I am the one who wrote
the backup script so I went
to grab the backup for
yesterday. Yup, you know
it. There wasn’t one. The
backup stopped working
back on July 3rd! Ouch.”
“Does the backup
through MySQL
Administrator have to
be saved in a certain
way to allow migration
to a new box?”
“Lesson learned – always backup regularly!”

Top considerations for a MySQL backup solution
• Performance
– Impact of the Backup Window
– How fast your restore needs to be? (RTO)
– How precise your restore needs to be? (RPO)
• Scale Up
– 10GB -> 100GB -> 1TB -> ??
– Organic growth
Longer retention
• Scale Out
– Wiki, Forums, Web registration database, Sugar, Alfresco, …..
– Multiple locations
• Security
– Aren’t you backing up your crown jewels?

Backup needs to match MySQL’s flexibility
• Today & Future
– MyISAM, InnoDB, Falcon …
• Replication
– Slave pauses replication -> Backup on slave ->
Resume replication
• MySQL Cluster
• Restores should hide all the complexity

Remote storage grid as a destination for backups
• Keep copy of data off-site yet
online with storage grid, e.g.
Amazon S3
• Pay for only what you use
(bandwidth and disk capacity)

• Backup data is always
available, anytime, anywhere
“We think users should seriously consider
• You can have the risk profile of
Amazon
adopting such hybrid [backup & online storage]
approaches to provide layered, efficient data
protection.” - John Webster, Analyst, Illuminata

Infrastructure for scalability
Scenario:
• 100+GB of database growing into Terabytes
• 24x7 application (i.e. no backup window)
• Active OLTP workload
• Need ability to restore to specific database event
Solution:
• Storage Snapshot + MySQL Logs
+ Automated Point-and-Click Restore

Snapshots – key considerations
• Snapshots scale extremely well as database size grows
• Need to be used carefully to ensure data consistency
• Need to be integrated with log-based incremental backups
