Best When

You want a self-hosted, encrypted, versioned backup tool and can run a desktop/server process with access to your backup storage.

Avoid When

You cannot run long-lived processes or you need strict transactional semantics across frequently changing datasets.

Use Cases

  • Automated encrypted backups of home/office PCs
  • Cloud-to-cloud or local-to-cloud backup workflows
  • Long-term versioned backups with deduplication/blocks
  • Disaster recovery restore testing
  • Backing up file sets with schedules and retention policies

Not For

  • Mission-critical database replication/point-in-time continuous replication
  • Low-latency synchronization use cases (backup is batch-oriented)
  • Environments requiring a managed hosted SaaS with guaranteed SLA

Known Gotchas

  • Duplicati is primarily an application/service, not a programmatic API package; agents may need to operate via CLI/UI rather than structured endpoints.
  • Backup/restore operations are stateful and time-consuming; agent retries may cause duplicated work or unintended scheduling impacts if not coordinated.
  • Encryption configuration and destination credentials are critical; agent automation should avoid logging secrets and should validate configuration before running long jobs.
