About Datto Drive
Datto Drive is the new FSS (file synchronization and sharing) service being launched by Datto in early 2016. Datto Drive uses hardware resources that are built, owned and managed by Datto in the Datto Cloud. Datto Drive leverages OwnCloud Enterprise.
Datto Drive is the first cost effective file sync and share platform for business, privately deployed and protected by the secure Datto Cloud. Easily enable Datto Drive locally or in the cloud to keep files and folders in sync across user devices, and share business files in- and outside of the organization. Automatically backup and recover files on-demand, ensuring business data is available even if servers fail.
Datto Technology
Datto Drive is an n-tier web application providing cloud protected file sync and share for businesses. Built on an industry standard LAMP stack, the system is comprised of Linux, Apache, MariaDB and PHP code, with some javascript for web browser UI interactions.
