Recebemos uma resposta de Brad Fitzpatrick, autor do Perkeep:
Em suma, parece que Perkeep tem a capacidade de mitigar os modos de falha de corrupção silenciosa, no entanto, não é atualmente um objetivo ativo do projeto.In Perkeep, every chunk of data and all metadata (which is just more data blobs) is named by its cryptographic digest, which is way stronger than simple filesystem checksum, or no checksums (like many filesystems).
The digests are validated when uploading new data to Perkeep, during replication, and at other times, but we don't really document or have a cohesive policy...
