Title: DETECTION OF BULK OPERATIONS ASSOCIATED WITH REMOTELY STORED CONTENT
Abstract:
Cloud-based storage services are provided for storing and/or sharing content across multiple devices, where the content is periodically synchronized between the devices and the storage service. Embodiments are directed to detection of bulk operations associated with content stored at a storage service to protect users both proactively and remedially from accidental and/or nefarious content alterations propagating to the storage service and/or other devices. A model may be created based on a usage pattern associated with the content, an attempted operation performed on the content may be detected, and the attempted operation may be compared to the model to determine whether the operation deviates from the usage pattern. If the attempted operation deviates from the usage pattern, a preservation policy for the content at the storage service may be modified and a notification of the attempted operation may be provided to obtain user approval.
