Longhorn
Cloud
Open source distributed block storage for Kubernetes, incubating at the CNCF
- From
- Free
- Rated
- -
The short version
- Each has a real cost: Duplicati no managed service or commercial support; Longhorn there is no vendor and no SLA, so a production incident at three in the morning is your own problem unless you buy SUSE Rancher Prime support separately.
- They diverge on capability: Duplicati covers AES-256 encryption, Longhorn covers Per-volume controllers.
- Prices and features above were last checked on 1 September 2026.

- Edge sites where shipping a storage array is impractical and three nodes is the whole clusternot Duplicati
- A K3s deployment where the storage layer must be light enough to run alongside the workloadsnot Duplicati
- A team that wants snapshots and S3 backups of persistent volumes without paying per-node storage licencesnot Duplicati
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Duplicati
- No managed service or commercial support
- Relies on community support
- No enterprise features
Longhorn
- There is no vendor and no SLA, so a production incident at three in the morning is your own problem unless you buy SUSE Rancher Prime support separately.
- Synchronous replication across nodes means write latency depends on the slowest replica and the network between nodes, which makes it a poor fit for latency-sensitive databases.
- Every replica is a full copy, so three-way replication consumes three times the raw capacity, unlike erasure-coded systems that are far more space efficient.
- It is designed for block storage on modest clusters and does not scale to the node counts or throughput that Ceph or a commercial array handles, so growth eventually forces a migration.
- Recovery from certain degraded states, such as a volume stuck detaching or replicas failing to rebuild, requires manual intervention and knowledge of Longhorn internals that is not widely held.

Answered from the vendors’ own pages
Duplicati: Is Duplicati free?
Yes. Duplicati is completely free and open-source under the LGPL license. There are no premium tiers, trials, or limitations.
SourceLonghorn: Who do we call when it breaks?
Nobody, unless you buy SUSE Rancher Prime, which includes commercial support for Longhorn. This is the decisive question for production use.
Duplicati: What does Duplicati support?
Duplicati supports zero-trust, fully encrypted backups to local storage, network drives, and cloud services. It includes deduplication and incremental backups.
SourceLonghorn: How much capacity does replication cost?
Full copies, so three replicas means three times the raw capacity. Budget accordingly rather than assuming erasure coding efficiency.
Duplicati: What are the platforms?
Duplicati runs on Windows, macOS, and Linux. It can back up data to local storage, network drives, or cloud providers.
SourceLonghorn: Is it suitable for production databases?
For modest workloads yes, but synchronous replication adds write latency and high-transaction databases usually want something faster.
