Optimizing disk volume scanning using snapshot metadata

Abstract:

Techniques for optimizing disk volume scanning using snapshot metadata are described. A method of optimizing disk volume scanning using snapshot metadata may include determining, by a scanning service of a provider network, a plurality of changed blocks between a current snapshot of a storage volume in a storage service of the provider network and a reference snapshot of the storage volume, determining one or more files that overlap at least one of the plurality of changed blocks, and scanning the one or more files for threats.
