Backups
MongoDB
Backups for MongoDB Atlas are performed on two levels. First, Atlas makes live backups using the Oplog and makes snapshots with the following schedule:
| Frequency Unit | Every | Retention Time |
|---|---|---|
| Hourly | 6 hours | 7 days |
| Daily | - | 7 days |
| Weekly | Saturday | 4 weeks |
| Monthly | Last day of month | 12 months |
To prevent loss in the event of deletion of a whole Atlas MongoDB cluster the latest snapshot is backuped monthly to S3 by a CronJob.
Note that, for now, both the Krane production cluster and the Sherpa clusters are backed up.
