Webinar: Backups + Disaster Recovery
Download as PPTX, PDF9 likes3,808 views
The document outlines MongoDB's backup and disaster recovery solutions, emphasizing the importance of meeting recovery point and time objectives (RPO/RTO). It discusses various backup strategies, including manual methods, automated tools like MongoDB Management Service (MMS) and Ops Manager, and the benefits of built-in replication for availability. Additionally, it offers insights on planning, setup, and monitoring for optimal backup management.

- 3. 3 Topics • Requirements around Availability and Backup • MongoDB Solutions • Tools for Backing up MongoDB
- 4. 4 Requirements • “I need my data to be readable/writable in the face of infrastructure failures” – Memory, disk, server, network, rack, data center • “Need tunable resiliency depending upon failure scenarios” • “I want to be able to get my data back to yesterday 3:05 PM because an application change caused some erroneous updates”
- 5. 5 Requirements • “I need my data to be readable/writable in the face of infrastructure failures” – Memory, disk, server, network, rack, data center • “Need tunable resiliency depending upon failure scenarios” • “I want to be able to get my data back to yesterday 3:05 PM because an application change caused some erroneous updates” Availability Backup
- 6. 6 Considerations Effort and Cost to meet availability and backup requirements driven by: • RPO: Recovery Point Objective – How much data can you afford to lose? • RTO: Recovery Time Objective – How long can you afford to be offline?
- 7. Availability
- 8. 8 • Automated replication and failover • Multi-data center support • Improved operational simplicity (e.g., upgrades, HW swaps) • Data durability and consistency MongoDB Replication for Availability
- 9. 9 Single Data Center Automated failover Tolerates server failures Tolerates rack failures Number of replicas defines failure tolerance
- 10. 10 Active/Active Data Center Tolerates server, rack, data center failures, network partitions
- 11. 11 Replication Advantage • Built into MongoDB, only ops and infrastructure cost • Meet RPO with tunable durability – Acknowledge write from 1 to majority members of a replica set • Down for a very short interval – Failover time is in seconds
- 12. Backup
- 13. 13 “We do not need backups for MongoDB” • We have replicated data • Multiple systems will not go down • We have good change control Why should you backup: https://www.mongodb.com/presentations/run-mongodb-confidence- backing-and-monitoring-mms
- 14. 14 Solutions for Backup Manual Automated • mongodump/mongorestore • Storage level backups • MongoDB Management Service or Ops Manager
- 15. 15 mongodump / mongorestore • Can be run online or offline • Oplog aware for point in time restores • Filter in, filter out • Considerations: – Data size/can be slow – Shard sync
- 16. 16 Storage level backups • Flavors: – Copy files in your data directory (e.g. /data/db) – File system or block storage snapshots • Fastest way to backup/restore • Considerations: – Journal/consistency – Backup granularity (whole file system back up?) – Ops expertise – Storage of snapshots or data file backups
- 17. 17 MongoDB Management Service (MMS) Ops Manager • Runs on our cloud (mms.mongodb.com) • Free service for Managing/Monitoring up to 8 servers • Paid service for Backup, First 1 GB Free • Runs in your cloud / data center • Included with MongoDB Enterprise Advanced http://www.mongodb.com/presentations/automate- mongodb-mongodb-management-service-mms http://www.mongodb.com/presentations/webinar- introducing-ops-manager Automation, for single-click provisioning, scaling & upgrades Monitoring, with charts, dashboards and alerts on 100+ metrics Backup and restore, with point-in-time recovery, support for sharded clusters
- 18. 18 Steps for Backup MMS Ops Manager (Infrastructure already exists in the cloud) Setup MMS for Automation and Monitoring Infrastructure Size and setup MMS Backup infrastructure Start to monitor (and/or manage) your MongoDB deployment Deploy backup agents Start taking backups
- 19. 19 Comparing backup approaches Mongodump File system MMS Backup Ops Manager Initial complexity Medium High Low High System overhead High Low Low Medium Point in time recovery of replica set Yes * No Yes Yes Consistent snapshot of sharded system Yes * Yes * Yes Yes Scalable No Yes Yes Yes Restore time Slow Fast Medium Medium * Possible, but need to write the tools and complex to setup and maintain NOTE: You cannot use MMS or OPS Manager to backup Standalone MongoDB
