Ransomware has the ability to cause a lot of problems for those who aren't prepared. Businesses and students can lose days or weeks worth of work, and consumers can find years worth of treasured photos are no longer accessible. People are bad at doing regular backups, and that's why ransomware protection is an important feature for storage and syncing products.

Microsoft is adding features to OneDrive and Office 365 that help protect against Ransomware from making user's files irrecoverable. Their solution is to bring the ‘Files Restore’ service from their business products and add it to consumer offerings. Files Restore allows users to restore their entire OneDrive storage back to any previous point within the last 30 days.

Initially, this feature was designed to protect against mass deletion or file corruption, i.e., situations where restoring files individually one-at-a-time isn’t a practical solution. Ransomware functions similarly to these events, so it would make sense that Files Restore works just as well for this sort of problem. Dropbox is one of the few alternatives that also offers bulk restore.

Manual backups stored separately from the computer, such as on an external hard drive or in online-only storage, help prevent the loss of files. But cloud storage and sync services have historically been vulnerable since a locked file would overwrite the original file during syncing.

To supplement Files Restore, Microsoft has added the ability to detect ransomware attacks into Office 365. A notification will be sent via email, desktop, and mobile (via the OneDrive app), and selecting this will load up the restore window to show the date and time of the attack with the option to restore to before that point.

We haven’t been able to clarify whether this applies to all paid versions of OneDrive or just the Office 365 version. The confusion comes from the way that OneDrive plan tiers work. Users can choose a smaller 50 GB OneDrive plan, but the 1 TB plan is called "Office 365" and comes with the full office suite, and Microsoft is advertising this as an Office 365 feature.

I grew up in a family surrounded by technology, starting with my father loading up games for me on a Commodore 64, and later on a 486. In the late 90's and early 00's I started learning how to tinker with Windows, while also playing around with Linux distributions, both of which gave me an interest for learning how to make software do what you want it to do, and modifying settings that aren't normally user accessible. After this I started building my own computers, and tearing laptops apart, which gave me an insight into hardware and how it works in a complete system. Now keeping up with the latest in hardware and software news is a passion of mine.
