Is TrueNAS replication a backup?

TrueNAS SCALE replication allows users to create one-time or regularly scheduled snapshots of data stored in pools, datasets or zvols on their SCALE system as a way to back up stored data.

The TrueNAS replication feature is often used as part of a comprehensive backup strategy, but it is not a standalone backup solution. While replication provides data redundancy and allows for failover in case of hardware failures or disasters, it does not fulfill all the requirements of a complete backup.

Replication in TrueNAS involves creating an exact copy of your datasets on another TrueNAS system, either locally or remotely. This copy serves as a synchronized replica that can be used for high availability or disaster recovery purposes. It ensures that your data is readily accessible in case of a primary system failure.

Accidental Deletions and Corruption: Replication propagates changes from the source dataset to the replica. If a file is accidentally deleted or corrupted on the source, these changes are mirrored in the replica, potentially resulting in data loss. A backup solution should include features like point-in-time snapshots or versioning to protect against such scenarios.

Ransomware Protection: Replication does not inherently protect against ransomware attacks. If your primary system is compromised, the replicated data may also be affected, leading to encrypted or inaccessible copies. A backup solution should include features like immutable backups or air-gapped storage to safeguard against ransomware threats.

Granularity and Retention: Replication typically mirrors entire datasets or file systems. If you need to recover a specific file or a previous version of a file, replication may not provide the necessary granularity or retention options. A backup solution allows you to selectively restore individual files or restore data from different points in time.

Human Error and Logical Failures: Replication may propagate human errors, such as accidental file modifications or data corruption. It also does not protect against logical failures like database corruption or software bugs. A backup solution with the ability to restore to a clean state or specific application-level backups can mitigate these risks.
