Technical deep dive into .ptar: replacing .tgz for petabyte-scale S3 archives
.tgz made sense in 1994, but today we need archiving that supports deduplication, encryption, S3, and zero trust. here’s why we built .ptar.

It doesn't make sense to wrap modern data in a 1979 format, introducing .ptar
.ptar is our own archive format, a self-contained kloset, a container for your data. You end up with a standalone file that provides deduplication, compression, encryption, with all of the fancy features of a kloset store !
Plakar v1.0.2 was released: mostly S3 improvements !

Audit of Plakar cryptography
Before releasing a usable version, we wanted an expert to examine our cryptographic design and confirm we hadn’t made any regrettable choices. We were delighted to have Jean-Philippe Aumasson take care of the review—a true privilege given the high level of confidence we have in his skills: he is a recognized cryptographer who created various widely-used algorithms, including ones used in plakar, and who authored great books on the topic, two of which are on my desk as I write this.
