16. MMS – Backups

17. Disasters: All Shapes & Sizes

18. Disasters: Many Causes

19. Risks Are Everywhere

20. Replication
• Redundant copies of your data across
– Servers
– Racks
– Data Centers
• Automatic failover
• Tunable consistency minimizes risk
• However…programmer errors will replicate
almost immediately!

21. Backups
Backing up data is one way to ensure availability and lower
risk. They require active engagement, otherwise:
•Backups can be outdated
•Process can be slow (backup or restore)
•Isolated
•…but they are relatively inexpensive and do well at
minimizing risk

22. MongoDB Backup Approaches

23. MMS – Maintenance Operations

24. The Process
• Applies to upgrades and most maintenance tasks
• Careful order of steps is critical
– Especially in sharded clusters!
• For each shard/replica set
– For each replica set member
• http://docs.mongodb.org/manual/tutorial/perform-maintence-
on-replica-set-members/

25. Step 1 – Stop A Secondary

26. Step 2 – Restart As Standalone

27. Step 3 – Perform Maintenance

28. Step 4 – Restart As Member of Replica
Set

29. Step 5 – Work on Primary Last
