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 They require active engagement, otherwise:•Backups can be outdated•Process can be slow (backup or restore)•Isolated•…but they are relatively inexpensive and do well at minimizing risk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
