Continuous backup
Continuous backup is the ongoing capture or archival of data changes so a system can be restored to a recent point after disruption.
MongoDB 8.0 in Action, Third Edition
Continuous cloud backup continuously captures database changes and write history to support restoration to a selected point within a retention window.
- How it is used
- Protects Atlas clusters against accidental deletion and corruption by retaining changes for recovery within a configured window.
- How deep it goes
- Explains snapshot-based oplog replay and shows a restore command, but defers continuous-backup setup details to documentation.
- Examples
- Shows an Atlas CLI point-in-time restore specifying a UNIX timestamp, source cluster, target cluster, and target project.
- What you can do after
- Apply it via the Atlas CLI to request and monitor a restore to a selected time within the retention window.

PostgreSQL Mistakes and How to Avoid Them
Continuous archiving is the ongoing preservation of database transaction-log segments so changes can be replayed during recovery.
- How it is used
- Enables point-in-time recovery beyond the state captured by the latest full backup.
- How deep it goes
- Explains configuration, backup-time WAL retention, recovery_target_time restoration, and restore testing without detailing archive-command implementations.
- Examples
- Uses recovery immediately before damage and a cascaded replication topology for redundancy and backup.
- What you can do after
- Operate/configure WAL archiving, base backups, timed recovery, redundant backup storage, and full-restore verification.
