2. Best practices for running
MySQL on production

3. Agenda:
Backup tool for MySQL
Importance of having basic HA
MySQL trouble shooting

4. Little about me:
Working for Techmojo solutions
Leading DBA and Production support engineering
MySQL user and try to contribute to forum and gain
knowledge
I thank MyDBOps and Karthik for inviting me!

5. Backup tool for MySQL:
# Disadvantages
Logical :
Comparitively takes longer time
Takes long to restore
For certain size it's not practical
Physical :
Storage intensive
Nobody can save you, but your backup can!
Types of Backup
Logical and Physical
# Advantages
Logical :
simple commands for backup and restore
storage efficent
Physical :
Faster to backup
Faster to restore
Also crons and config files and may be mysql users in
some cases
# Monitoring backup
# Test backups

6. Importance of having basic HA:
Why HA?
HA is your friend. :)
1. Fault tolrant architecture
2. Avoid SPOF (Single point of Failure)
3.Your replica is for protecting against the downtime due to HW, SF, DC,
Network failure but not for data loss!
In other words replica can't be your backup strategy!
4.It protects from unplanned downtime and helpful to reduce the unplanned
downtime
5. High availability = High cost and not having HA can cost more than HA cost !

7. MySQL trouble shooting:
Define your problem (it may evolve over the period)
Have concave approach
1. Start with resources
2. Check the historic resource utilization
3. Check the pattern if any
4. Check for latest changes / deployments
5. Compare the query behavior
6. Hunt for newly added queries (monsters)
7. Define what is your benchmark
8. Know your application well
Tools can be helpful

8. Run it like you OWN it!!
Keep a watch on access
Audit privileges periodically
Backup test plan
HA health
Performace reports
Table growth
Top 10 alerts
Top 10 slow queries
Robust SDLC system to filter thing before it goes out to Prod
