Great work! What I feel skeptical about, is the fact that plakar is not self-contained, but has a dependency. That gives me a pause. What I’d love to see is one single binary that I can just install and use.

Author here, plakar is a single binary, unsure I understand what it is you’d prefer, a ptar specific executable?

Thanks for replying. Maybe I misunderstood something. The way I saw it, I can not use plakar without having to install Go first (the dependency). And that bothers me a bit.

Let me explain my reasoning. Suppose I made an .ptar archive today, put it on a USB stick, threw that in a vault and forgot about it. Ten years down the road I want to restore that archive. But the .ptar file alone is useless without the plakar tool. So I have to install plakar first. Ideally plakar should sit on that USB stick, right next to the archive, ready to be installed. But plakar is dependent on Go, so I have to hunt Go first. And who knows what the state of Go will be ten years down the road. The .ptar file that I made today may end up unusable ten years later, because Go evolved in some unpredictable way.

This is really neat... plakar itself looks like an awesome backup tool. We use Borg now but I'll be testing this out.

So another WIM like format?

Not exactly, if WIM is a complete snapshot of a Windows disk ready to be restored on an identical machine, .ptar is a self-contained capsule holding successive, encrypted, deduplicated, and verifiable versions of any dataset, portable and usable across different environments.
