MongoDB backup plan

Question

I want to switch from MySQL to MongoDB but great data losses (more than 1 hour) are not acceptable for me.

I need to have 3 backup plans:

1. Hourly

Answer 1

If you want to outsource the backup solution entirely, MongoDB Management Service takes snapshots every six hours. The default retention policy on the snapshots will allow you to get point-in-time restore for 24 hours, daily snapshots for a week, weekly snapshots for a month, and monthly snapshots for a year.

This FAQ has the full retention policy.

The backup service continually backs up your replica set by reading the oplog so the overhead is lower than full local periodic snapshots.
