Recover from Advanced Malware Attacks Using The Snapshot Feature
Overview
The Snapshot feature allows administrators to easily copy a Team Share or a user’s personal data as it existed at a specific point in time, including content that was previously deleted, recreated, or changed. This feature even recovers the revision history of restored content, starting from the selected date.
The Snapshot Feature and Ransomware
Ransomware is a type of malware that denies access to infected content, and demands that the user pay a ransom to remove the restriction. In many instances, you can use Anchor’s Restore Deleted and Revision Rollback feature to restore affected files to their previous, healthy revisions.
Advanced ransomware attacks—such as Locky—might delete, recreate, then change files names, thereby affecting a file’s revision history, and preventing you from restoring to a previous revision. The Snapshot feature helps you recover from these advanced attacks, allowing you to restore data as it existed before infection.
The Snapshot feature is one of many AXIS Cloud Sync features that help protect and restore data. For more information on AXIS Cloud Sync’s data restore options, please reference the following Knowledgebase articles:
- The Restore Revisions feature allows you to restore one file to a previous revision
- The Revision Rollback feature helps you recover from many variants of ransomware; the feature utilizes a file’s revision history to restore all currently-existing content to a healthy revision
- The Restore Deleted feature allows you to restore a file that has been previously marked as deleted
Other Use Cases
In addition to ransomware recovery, you can also use the Snapshot feature for data management or archive purposes. For example, if an employee resigns from an organization, you might decide to clone his personal root folder as a Team Share and retain this content as a record or archive.
A Technical Note About Purged Files and Folders
Please note that purged files and folders cannot be recovered using this feature. Purged files and folders are defined as:
- Files and folders that have been deleted and then purged
- Files and folders that have been deleted, purged, and then manually recreated
- Files and folders that have been moved from a folder location that is later deleted and purged; in these instances, the revisions captured in the original folder location will not be recovered
Purge settings can be managed as an organization policy.
