A cloud-native global file system, in which one or more filers are associated with a volume of a versioned files system in a private, public or hybrid cloud object store, is augmented to include a rapid ransomware recovery service. Upon detecting a ransomware attack associated with one or more files or directories of the volume, read and write access to the volume is restricted. A recovery filer is then activated or designated in the cloud. A restore operation is then initiated at the recovery filter. Following completion of the restore operation, a new clean (healthy) snapshot of the volume is then created using the recovery filer For any filer other than the recovery filer, a determination is made whether the filer has completed a merge operation with respect to the new clean snapshot. If so, read and write access to the volume is re-enabled from that filer.

Cloud-native global file system with rapid ransomware recovery

A cloud native global file system is augmented to include a 'file accelerator' that is configured to speed up data propagation with respect to updates on a shared volume and, in particular by performing real-time analysis on audit event data to coordinate pushes and pulls across multiple edge appliances, effectively replacing static snapshot and synchronization schedules. A “push” refers to a snapshot on the volume that occurs at a particular filer, and a “pull” refers to a synchronization (sync) operation initiated by a particular filer to obtain whatever is in the cloud (and that is the subject of the pull). The file accelerator operates in several modes of “triggered” operation based on user activity, and under the control of a cloud-based controller.
