Abstract:
The present disclosure describes systems and methods for detection and mitigation of malicious activity regarding user data by a network backup system. In a first aspect, a backup system receiving and deduplicating backup data from a plurality of computing devices may detect, based on changes in uniqueness or shared rates for files, atypical modifications to common files, and may take steps to mitigate any potential attack by maintaining versions of the common files prior to the modifications or locking backup snapshots. In a second aspect, the backup system may monitor file modification behaviors on a single device, relative to practices of an aggregated plurality of devices. Upon detection of potentially malicious modification activity, a previously backed up or synchronized store of data may be locked and/or duplicated, preventing any of the malicious modifications from being transferred to the backup system.

Claim (Index 12):
The method of  claim 8 , wherein the calculating comprises identifying different ones of the patterns of the legitimate file activity for different rates of file modification over time.
