Abstract
A method for detecting a modification to stored data includes continuously creating a point-in-time copy of a storage level logical unit, the point-in-time copy comprising a volume copy of the storage level logical unit and a signature of the storage level logical unit, comparing at least a portion of the point-in-time copy with a previous copy of the storage level logical unit, and monitoring, based on the comparing, changes on certain logical blocks of the stored data, using the signature of the storage level logical unit.
