How Datto manages trust within a fleet of devices

Learn how Datto manages the rollout of trusted root certificates to a fleet of hundreds of thousands of devices without causing a single failed backup!

Unifying Our User Interfaces

Datto has a lot of great products in its arsenal that only keeps growing as we acquire more businesses. Because of this, integration is very important and a key item of that is user experience. To accomplish this, we knew we had to streamline our user interfaces. As product designers, we are advocates for the user and have a proclivity for good aesthetics. So for us, this was not only a time to stretch our visual design muscles but to also improve the usability across our products.

Understanding chkdsk for NTFS

chkdsk is a utility from Microsoft that tries to fix a volume’s file system without losing data. It checks for both logical and physical errors. chkdsk usually checks the file system metadata information first and applies file system repair functions if necessary. At Datto, we mostly deal with NTFS, so in this post, I'll only discuss the NTFS file system.

Keeping it simple: Using Server-Sent Events (SSE) to power a live UI

Ever wonder how your favorite web-based app gets real-time updates without a page refresh? We wanted to do this for one of our networking products, but there are many ways to go about it. Here's how we ended up at one less well-known solution for building a live-updating web UI.

Putting the devices you know and love into our cloud

One of Datto’s ongoing missions is continually improving and advancing our cloud offerings. The SIRIS has proven itself over and over again to perform well with local restores, so why haven’t we put them in Datto’s cloud? By putting SIRIS in Datto's cloud we can improve two products offerings simultaneously without needing to adjust our test suites or even change our hardware.
