Abstract
Systems and methods are provided for tracking sensitive data within a plurality of storage units, where storage units include block storage volume(s) and/or 'snapshot(s)' representing values of every block of a block storage volume or device at a particular point in time. A computing device may be configured to receive a notification identifying a first tainted storage unit. Subsequently, a subset of the plurality of storage units may be identified. Additional tainted storage units can be identified as tainted within the subset. This identification may depend on whether the storage units contain data blocks in common with the first tainted storage unit. Remedial action may be taken for storage units identified as tainted.
