The short version

  • Each has a real cost: Datto SIRIS requires on-premises appliance, not purely cloud-native; Panzura cloud egress charges apply whenever data is read from the object store into a site that has not cached it, and organisations routinely discover this during a restore or a new site rollout rather than during procurement.
  • They diverge on capability: Datto SIRIS covers Instant virtualization, Panzura covers Global file system.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Datto SIRIS

  • Requires on-premises appliance, not purely cloud-native
  • Initial setup and hardware costs can be substantial for smaller MSPs

Panzura

  • Cloud egress charges apply whenever data is read from the object store into a site that has not cached it, and organisations routinely discover this during a restore or a new site rollout rather than during procurement.
  • Performance depends entirely on cache hit rates, so a team that works across the whole dataset rather than a hot subset sees latency that a local NAS would not have produced.
  • Licence cost is only part of total cost; object storage capacity, per-site filer nodes and egress all sit outside the vendor quote and can exceed it.
  • Recovery of a very large dataset is bounded by your internet link and by egress cost, so the practical recovery time after a site loss is often much longer than the snapshot policy implies.
  • Encryption keys can be held by the customer, but organisations that accept vendor-managed defaults give up the ability to render the object store unreadable independently, which some regulators now ask about explicitly.

Answered from the vendors’ own pages

Datto SIRIS: What does SIRIS protect against?

Datto SIRIS includes immutable cloud backups, automated recovery verification, and integrated ransomware detection through Cloud Deletion Defense which undoes accidental or malicious backup deletion.

Source
Panzura: Who holds the encryption keys?

Customer-managed keys are supported. Insist on them if you need the ability to revoke access to the object store independently of the vendor, and confirm the key custody model in writing.

Datto SIRIS: What's the pricing model?

Datto SIRIS uses flat-rate pricing starting at $1,095, which includes installation, storage, VIP support, recoveries, two annual DR tests, and five-year warranty.

Source
Panzura: What does it actually cost to run?

Model three things: the Panzura subscription, the object storage capacity, and cloud egress. The third is the one that catches buyers out during restores and site bring-ups.

Datto SIRIS: What integrations does SIRIS have?

Datto SIRIS integrates natively with Autotask PSA, Datto RMM, ConnectWise Automate, and ConnectWise PSA. It also supports virtualization platforms like vSphere and CentOS Linux.

Source
Panzura: Does it replace backup?

Immutable snapshots cover many recovery scenarios, but confirm your retention and compliance requirements before removing an existing backup product.

Datto SIRIS: Is SIRIS cloud-only or appliance-based?

Datto SIRIS is an on-premises appliance that backs up data to Datto's cloud. You do not need to maintain your own physical server infrastructure for the core SIRIS functionality.
