Atlas Backups — MongoDB Technical Interview Questions & Answers

Automated continuous and scheduled backups.

Atlas Backups

  • Simple meaning: Atlas can snapshot your cluster on a schedule (paid tiers have continuous backup). M0 has limited/no continuous backup — dump important homework yourself.
  • How to use: Atlas Backup (or Cloud Backup) in the cluster menu if your tier includes it. Else mongodump with the SRV URI.
  • Common mistake: assuming free M0 has point-in-time restore like paid clusters.
  • Interview tip: Managed backups on paid Atlas. mongodump still works everywhere.

Technical Interview Tip: Know your tier’s backup. Dump if unsure.
