Datto SIRIS
Your servers sit in one office. A fire or ransomware there shouldn’t take the business with it — Datto SIRIS and ALTO image your servers to an appliance on site and to the private Datto Cloud — and boot a failed system as a virtual machine on either, with daily proof that every backup starts.

Understand BCDR before you buy it
Most product pages skip this. We start here — so you buy a capability, not a buzzword.
What is BCDR?
Business continuity and disaster recovery means keeping a backup that can run your systems, not just restore files, when a server or site is lost.
A NAS copy and a hope vs Datto SIRIS — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | A NAS copy and a hope | Datto SIRIS |
|---|---|---|
| When a server dies | Order parts, rebuild, restore for days | Boot it as a VM on the appliance in minutes |
| When the office is lost | No second site, no plan | Run the servers in the Datto Cloud until rebuilt |
| Knowing backups work | A green tick nobody checks | Daily boot screenshot plus service scripts |
| Paying for hardware | A NAS or server bought and depreciated | Appliance included; returned when you leave |
| Ransomware on backups | Shares the attacker can encrypt | Hardened Linux box and an immutable cloud copy |
| What it is NOT | — | A production cloud, or failover to Azure or AWS |
The cheapest test is a cloud DR drill: ask the MSP to boot your most important server in the Datto Cloud and time it against your target.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
Appliance
A hardened Linux appliance on your premises in micro PC, desktop or rack form — SIRIS 6 racks are Dell PowerEdge-based — or software-only SIRIS as a VM on hardware you own.
Capture
Agents image physical and virtual Windows and Linux servers; VMware is backed up agentless. Every incremental snapshot is stored as a complete, bootable recovery point.
Cloud
Snapshots replicate to Datto’s own cloud, nine sites across seven countries with Singapore closest to India, kept one year, seven years or indefinitely by tier.
Portal
Your MSP manages every appliance, restore and DR test from one portal with enforced two-factor sign-in, and raises tickets in Autotask PSA or alerts in Datto RMM.
An appliance on your premises and a private Datto Cloud — either one can boot a failed server as a virtual machine.
Nine capabilities. Protect, verify, recover.
Datto SIRIS gives a small business what it rarely owns: a backup that can run its servers, on site or in Datto’s cloud.
Backups as often as every 5 minutes
Incremental snapshots can run every five minutes by Datto’s figure, application-aware for SQL Server, Exchange and SharePoint.
Every snapshot is bootable
Inverse Chain Technology keeps each incremental as a fully built recovery point, so no restore waits on replaying a long chain.
Hardened box, immutable cloud
A hardened Linux appliance with ZFS snapshots, ransomware scanning of backups, an immutable Datto Cloud and Cloud Deletion Defense.
Screenshot proof that it boots
Since March 2026, AI-powered screenshot verification starts every backup as a VM, and scripts then confirm that named services run.
Drills without a test bill
Datto lists no charge for disaster recovery testing and offers support-assisted tests, so a drill never has to wait for budget.
One year, seven years or infinite
Cloud retention is bought as a 1-year or 7-year time-based tier, or Infinite Cloud Retention held while the subscription is current.
Failed servers run as VMs
A failed system boots as a VM, locally on the appliance or up in the Datto Cloud; Datto claims an average RTO under six minutes for this step.
Failover from tested set-ups
1-Click DR launches cloned VMs and their network configuration from set-ups tested in advance, rather than wiring them mid-crisis.
From one file to bare metal
File and folder restore, Rapid Rollback, image export, bare-metal restore and Fast Failback to repaired hardware, all in one place.

Want a live, India-context walkthrough for your environment?
Book a guided demo →A small business rarely has a second site. SIRIS gives it two: the appliance and the Datto Cloud.
Here’s what genuinely sets it apart — and exactly where it stops.
Proof, every day, that the backup boots
Most backup failures surface on the worst day. SIRIS boots each backup, takes a screenshot that AI checks, and runs scripts to confirm services start — so an auditor or insurer gets evidence, not a green tick. Every snapshot is a full recovery point, and DR tests carry no charge.
A second site you do not have to build
A small firm rarely owns a DR site. SIRIS gives it two: the appliance can run failed servers locally, and the private Datto Cloud can run them off site after a fire or flood, with 1-Click DR restoring the tested network set-up. Datto says there are no ad-hoc charges for ingress, egress or DR.
Hardware without a capital budget
Since November 2024 the appliance comes with the subscription for any term, month-to-month included, so there is no box to buy or depreciate. The fee is flat per appliance, set by capacity and retention tier. The catch: the hardware is Datto’s and goes back within 30 days of cancelling.
Where it stops
No price is published and Datto sells through MSPs. Failover runs in the Datto Cloud only, never Azure or AWS, and only for emergencies and tests, not as a production home. No Datto data centre is in India; Singapore is nearest. Datto holds no Gartner Magic Quadrant placement.
The numbers behind the platform
What your Datto SIRIS rollout looks like
Rank systems by downtime
List every server and VM, set an honest RPO and RTO for each, and note which data may leave India for Singapore.
Size the appliance and tier
Choose SIRIS or ALTO, the capacity and a 1-year, 7-year or infinite retention tier, then compare quotes from MSPs.
Install and seed
The MSP installs the appliance or virtual SIRIS, protects each server, and seeds the first full images to the Datto Cloud.
Run a cloud DR drill
Boot key servers in the Datto Cloud with 1-Click DR, test the VPN path for staff, and time the recovery against your RTO.
Make proof routine
Send screenshot verification reports to whoever answers to auditors or insurers, and book a DR test every quarter.

Quick poll — what’s driving your evaluation?
Talk to an advisor“Our file server’s RAID died on a Monday. The MSP booted it as a VM on the SIRIS box and staff were working again before lunch.”
“The screenshot of each backup booting is what our cyber-insurance renewal asked for. We forward the report instead of writing one.”
“We ran a full cloud failover drill with our MSP and paid nothing extra for it. The VPN to the Datto Cloud took longest to set up.”
“Our cloud copy sits in Singapore, not India. For our data it was acceptable, but get the storage location in the contract first.”
“An ALTO covers our three servers and a desktop. It is quiet, sits in a cupboard and the MSP watches it; we rarely think about it.”
“There is no price list, so we compared three MSP quotes. The flat fee is predictable, but it took weeks to see what we were paying for.”

Which approach fits you?
Honest fit signals — because the fastest way to lose your trust is to pretend one product wins every scenario.
Choose Datto SIRIS if…
- ✓You have no second site and want an MSP to give you one, on the appliance and in the Datto Cloud
- ✓Insurers or auditors want daily proof that backups boot, not a success log
- ✓You would rather pay a flat monthly fee than buy and depreciate backup hardware
Compare alternatives if…
- ✓Backups must be stored in India — Acronis has a Mumbai data centre and Veeam Vault has Azure India regions
- ✓You want to fail over into Azure or your own site — Cove, Acronis and Veeam all allow it
- ✓You run IT in-house and want a published price — Veeam Vault lists per-TB rates
Do not expect…
- ✓A published price, or a way to buy without an MSP in most cases
- ✓Failover to Azure or AWS, or running production in the Datto Cloud for months
- ✓A Datto data centre in India, or a Gartner Magic Quadrant placement
Datto SIRIS is one of 27 disaster recovery products TechBag carries. The Disaster Recovery guide narrows them to a shortlist and shows the reasoning. →
What does hand-checked backup and slow recovery cost you?
Drag the sliders (servers and VMs you protect; IT staff-hour cost). Estimates model staff time spent checking backups by hand, running restore tests and rebuilding after failures, at an assumed 1.5 hours per server a year, with 70% of it removed by automatic boot verification and one-click virtualisation. Both figures are assumptions. Illustrative.
Loaded cost = salary + overheads per productive hour. Illustrative only — your TechBag quote models your actual environment and modules.
Three ways to consume it
Not published. Datto shows only a quote form and says it works exclusively with MSP partners, so an Indian business normally buys SIRIS or ALTO through an MSP, in US dollars. The fee is flat and monthly per appliance, set by capacity and by retention tier (1-year or 7-year time-based, or Infinite Cloud Retention), with the hardware, cloud storage, cloud virtualisation and DR testing included. Terms run month-to-month or committed; the hardware goes back within 30 days of cancelling. SIRIS is not part of any Kaseya 365 bundle. TechBag sizes the appliance and tier first, then compares MSP quotes.
Datto ALTO
Best for a small office with a few servers
- Protects up to four agents
- Desktop appliance, same Datto Cloud
- Price by quote through an MSP
+ Platform add-ons
Best for a broader rollout
- Scoped to your estate
- Add-on modules as needed
- Phased, right-sized deployment
Datto SIRIS
Best for multi-server sites that need cloud DR
- Micro PC, desktop, rack or virtual
- Hardware included; returned on exit
- 1-year, 7-year or infinite retention

The 8 questions to ask every vendor
Take this into your next vendor call — including ours.
Which systems must be back within an hour? Test Datto’s under-six-minute average claim against your own servers.
May backups be stored in Singapore? No Datto data centre is in India; only the on-site appliance copy stays here.
Do you need failover into Azure or AWS? SIRIS runs failed servers only locally or in Datto’s own cloud.
How long must backups be kept — one year, seven years or indefinitely? The tier sets the monthly fee.
Which MSP will run it, and who at your firm gets portal access, restore rights and the verification reports?
Are you ready to return the appliance within 30 days of cancelling, with cloud copies deleted after 60 days?
Do you run Hyper-V? Agentless Hyper-V was announced for June 2026; confirm with your MSP that it has shipped.
Will finance accept a US-dollar fee billed by an MSP, month-to-month or on a committed term that auto-renews?
