siris-hero-diagram Run the power of SIRIS in your existing Virtual infrastructure. Backup to local datastores, then move the data to the Datto Cloud. Create local instant virtualizations of physical or virtual sources, with failover to the cloud. Secure multi-site Disaster Recovery as a Service for any SIRIS deployment method. The Datto Cloud provides hosting for virtualized systems, giving businesses with any budget access to low-RTO business continuity. Datto's purpose-built BCDR appliances provide high-performance local backup, a local business continuity host, and a gateway to the Datto Cloud and DRaaS from Datto. Retain your investment in existing infrastructure, or supply your own hardware. Use a Datto-provided USB thumb drive to re- image it into a SIRIS device—with all the power of SIRIS backup, instant virtualization, and protection in the Datto Cloud. SIRIS 3 Cloud Virtual Imaged Hardware

A data protection platform for today’s business

Data backup, recovery and business continuity for local, virtual and cloud environments, within a single platform.

Complete data backup, recovery and business continuity in one platform

Datto SIRIS 3 is the first complete data protection and business continuity solution delivered on one platform. The SIRIS 3 solution can be deployed on a purpose-built Datto appliance, in a virtualized environment, or imaged for use on existing hardware.

Business data can be backed up to a local device in real time and synchronized with the 250+ PB Datto Cloud, which provides geo-redundancy, data integrity and location-specific sovereignty.

SIRIS 3 comes complete with Instant Virtualization technology that enables whole infrastructures to be spun up in a matter of seconds, either on a local device or in the cloud. As such, SIRIS 3 significantly reduces RPO (Recovery Point Objective) and RTO (Recovery Time Objective) for small and mid-sized businesses.


Datto Appliance

Datto’s purpose-built SIRIS 3 high-performance appliances are tailored to the specific requirements of the SIRIS solution and packed with the latest generation of components. Each comes complete with multiple 10 gigabit ethernet interfaces and the latest generation of multi-core Intel XEON CPUs and DDR4 memory for increased performance as well as an IPMI for remote lights-out management. Built and unit-tested by Datto all devices come with a standard 5-year warranty. Storage capacity ranges from 500GB to 60TB, with field upgrades available to provide additional capacity as your business scales.

Datto SIRIS 2

Nuvoton Board Management Controller (IPMI)

IPMI provides remote access to multiple users from different locations. It also allows a system administrator to monitor system health and manage computer events from a remote location. IPMI works independently of the operating system as a separate micro-controller. When used in conjunction with the IPMIView, system administrators can remotely access, monitor, diagnose, and manage their Datto devices.

Supported on all SIRIS Professional and Enterprise models.

10GbE NICs

All SIRIS 3 Professional and Enterprise systems have two 10GbE RJ-45 NICs on a dedicated PCI Express lane.

Up to 1TB of of ECC memory

The installed memory on the SIRIS appliances range from 16gb (on the X1 device) - 128Gb (on the 60TB device)


Three field-replaceable cooling fans for cooling redundancy and maximum cooling. SIRIS also uses Dynatron CPU heatsinks, and is assembled in our build facility with meticulous care to keep cables out of the path of airflow.

Up to 24 hot-swap drives

SIRIS 3 systems (other than X1) use hot-swap drive bays, enabling service technicians to provide non-disruptive onsite field replacement. SIRIS systems use 7200rpm drives with SATA 6 Gb/s

SATA interfaces and 64MB of cache. ZFS uses write coalescing to eliminate traditional RAID read-modify-write performance overhead, and maximize throughput during backup operations.

Internal SSDs for OS and cache

Operating system resides on dedicated partition on enterprise SSDs that are hot-swappable from rear of chassis. OS Drive includes a cache partition of 43GB (Business models) or 103GB (Pro & Enterprise models), 1x Kingston SSD. SIRIS firmware can be reloaded after an upgrade in as little as 10 seconds. The drives are partitioned to create a large L2 cache for ZFS.

Hot-Swappable Power Supplies

All SIRIS Professional and Enterprise models have two redundant, hot-swap power supply modules. They automatically sense the input voltage between 100v to 240v, and operate at that voltage.

LSI Disk Controller

An LSI 2308 SAS Controller is used on SIRIS Enterprise units, and assembled with redundant internal connections to the hard drives. This 6.0gbs SAS 2 or SATA III based controller has native PCIe 3.0 connectivity.



The Datto SIRIS 3 X1 provides the full feature set of the SIRIS 3 platform delivered as a small form-factor all-flash device. Intended as an entry level SIRIS deployment appliance, the X1 is licensed to protect a single server, comes with a 1TB solid state drive and 16GB of RAM and can perform local virtualization directly on the appliance.

SIRIS 3 Virtual


The Datto SIRIS 3 Virtual appliance provides the full feature set of the SIRIS 3 platform for businesses that prefer implementing a virtualized service. SIRIS 3 Virtual supports VMware vSphere, Microsoft Hyper-V, and Citrix XenServer and is available in an array of local storage options, ranging from 500GB to 60TB.



Datto SIRIS 3 Imaged is a SIRIS 3 appliance built using a USB-based imaging tool that can convert a wide array of backup, disaster recovery (BDR) appliances, and other user-provided hardware, into a full feature Datto SIRIS 3 appliance. A SIRIS 3 Imaged appliance contains the entire SIRIS 3 platform.


Datto utilizes Hybrid Cloud technology to improve redundancy and give users greater protection for their systems and data. The SIRIS appliance provides workstations and servers with local data protection. From there it is automatically and securely transmitted to the secure Datto Cloud, providing local and remote data protection and Disaster Recovery as a Service (DRaaS). All with a solution that can literally be installed and protecting servers in minutes.

Datto uses image-based backup technology to take a complete picture of the workstation or server. This, combined with Inverse Chain Technology makes backup dependency chains a thing of the past. Each backup is fully independent from previous backups, providing maximum data integrity while optimizing storage efficiency.


Instant Virtualization allows image-level backups of on-prem servers (physical and virtual) to be virtualized locally on the Datto appliance or in Datto's secure cloud. Ten second launch times regardless of the recovery point selected.

Automated Backup Verification

Screenshot Backup Verification automatically validates backup integrity after completion. Large quantities of protected servers, even across a fleet of Datto appliances, can have backups validated at a frequency never before possible. Screenshot Backup Verification is supported on both Windows and Linux (an industry first!)
