MMS – Backups
Disasters: All Shapes & Sizes
Disasters: Many Causes
Risks Are Everywhere
Replication
• Redundant copies of your data across– Servers– Racks– Data Centers
• Automatic failover• Tunable consistency minimizes risk• However…programmer errors will replicate
almost immediately!
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 They require active engagement, otherwise:•Backups can be outdated•Process can be slow (backup or restore)•Isolated•…but they are relatively inexpensive and do well at minimizing risk
MongoDB Backup Approaches
MMS – Maintenance Operations
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/
Step 1 – Stop A Secondary
Step 2 – Restart As Standalone
Step 3 – Perform Maintenance
Step 4 – Restart As Member of Replica Set
Step 5 – Work on Primary Last
