Disaster Recovery & Business Continuity

Hybrid On-Premise and Cloud Data Protection

To virtualize and run a protected server with Hybrid Virtualization, ALTO initializes a virtual machine (VM) for that server in the secure Datto Cloud. Then the ALTO automatically connects that VM in the Datto Cloud to the local network through the ALTO, using a secure VPN tunnel.

Ensure offsite data protection by sending backup copies to Datto’s own secure 300PB+ Cloud

Fast initial data pre-seeding makes getting protected fast and easy.

Full-server Instant Failover to the Cloud

Datto protects systems from site-wide outages using instant off-site virtualization.

Ransomware Protection

Unique, Automatic Ransomware Detection and Alerting

Datto rocked the industry when it announced the first ransomware detection feature as part of the Datto Total Data Protection platform.

Don’t Pay the Ransom: Roll back servers to moments before Ransomware attacks

Even from the very first backup, Datto uses several proprietary methods for detecting the presence of ransomware.

Instant Hybrid Virtualization gets critical servers - and you - back in business right away.

Asset 1 datto Datto Cloud Virtual Environments Physical Servers Datto Device Physical or Virtual VM VM

A complex combination of standard and proprietary software integrated into a single Data Protection platform.

Datto ZFS
Ubuntu 16.04
Next-Gen Datto BMR


Datto’s proprietary weighted replication algorithm that enables ALTO to more efficiently sync data with the Datto Cloud.

Built on the efficient LZMA2 compression algorithm, SpeedSync enables multiple images to be pushed off site to the Datto Cloud at one time, subject to bandwidth throttling settings.

Datto ZFS

The base filesystem used in the ALTO built on industry standard ZFS. It provides protection against data corruption, support for high storage capacities, efficient data compression, integration of the concepts of filesystem and volume management, snapshots, copy-on-write clones, and RAID.

It is used as the basis for continuous integrity checking and automatic repair with enhancements to enable Inverse Chains, Instant Virtualization, and a host of other capabilities.


The most popular general purpose web server in the world, running more than half the world’s websites.

Apache provides the basic web hosting capabilities for the Remote Web management connection, web based file restores, web based NAS file access, and ownCloud on ALTO.


The latest and most performant release of the popular PHP web development platform combined with the benefits of the FastCGI Process Manager.

PHP is the application language for the ALTO platform, and FPM is the mechanism used by Apache to turn PHP into executable bits at runtime. This combination dramatically enhances ALTO performance, while enabling better memory management, adaptive process spawning and other goodies that make the ALTO platform more capable across the board.


Also known as Kernel-based Virtual Machine, this highly performant enterprise class virtualization host is embedded in every ALTO hardware and software appliance.

It is used for all local device virtualization, all screenshot verifications, and to generate Backup Insights file lists for individual file restores.

Ubuntu 16.04

The latest release of one of the most popular Linux variants on the market, providing enterprise class security, manageability, and performance in a small footprint.

Ubuntu is the basic operating system for all ALTO products, and supports many standard packages that ALTO uses as building blocks for the platform.

Next-Gen Datto BMR

Newly re-engineered to provide faster, more resilient bare metal restore options, BMR creates a bootable USB to plug into and image replacement hardware.

Simply create a BMR USB stick, plug it into the destination, and select the image to restore. Images and drivers are pulled in as needed to make this a fast restore process, and get the systems back up and running on new hardware fast.
