2026 Backup Tools Benchmark: Velero 2.0 vs Restic 0.17 vs Duplicati 2.0 for 1TB Data

Intro: As data volumes grow, choosing the right backup tool is critical. This benchmark tests three leading open-source backup tools — Velero 2.0, Restic 0.17, and Duplicati 2.0 — against 1TB of mixed workload data (documents, media, databases, VM snapshots) to evaluate performance, efficiency, and reliability.

Test Methodology

All tests ran on a dedicated server with 16 vCPUs, 64GB RAM, 2TB NVMe SSD storage, and 10Gbps network connectivity. The 1TB test dataset included:

300GB of small files (<1MB, documents, configs)

400GB of medium files (1MB-1GB, images, logs)

300GB of large files (>1GB, video, database dumps, VM images)

Each tool was tested for:

Initial full backup speed

Incremental backup speed (after 10% data change)

Storage compression/deduplication efficiency

Restore speed (full and single-file)

Reliability (error rates over 10 consecutive runs)
