Abstract: After completion of a backup job, the illustrative system performs a threat analysis of the freshly generated backup copies. Each copy is restored at a secure storage area. The system scans the restored data using, preferably, a signature-based malware scanning engine. If the scan finds malware infection or some other unsafe condition, a tracking index is updated to indicate that the copy is unsafe, and the secondary copy is quarantined. The quarantine prevents the copy from being restored to the production environment, and from acting as a source for other copies. The system iterates, scanning preceding versions of the copy, updating the index, and quarantining, until a clean or uninfected copy is found. The clean copy is so indexed. Responsive to a restore request, the illustrative system automatically restores the clean copy and skips over the infected copy/copies, preferably without asking the requesting user for input or approval.
