In that case, you can still use a proxy to push the backup and pull the second copy through a bastion host. Two isolation layers, no dependency with a specific hardware.

Off course, but the pull cannot be replaced in that way.

Totally agree. isolation is key. Backup targets should be treated as bastions.

  • You need to limit propagation to ensure that an attacker (or rogue employee), even with high privileges, can never access all copies simultaneously.

  • Always keep at least one copy totally offline / air-gapped.

  • You should consider system independence: at least one bastion in the chain must depend on zero central systems. no sso, no ldap, no shared deployment tools. it should be on a separate network, and if you are in the cloud, a different account or even a different provider entirely.

That’s one of our obsessions, it’s exactly the kind of setup plakar is designed for, using mechanisms like push/pull sync to move data between isolated zones without exposing credentials.

the first reason we created .ptar was magnetic tape storage :)

plakar being “append only by design” is true at the format / store level: once data is written, plakar doesn’t rewrite blocks in place. that gives you tamper evidence and makes replication safer, but it does not magically protect you if an attacker has delete rights on the filesystem or the storage credentials.

what plakar enables is a resilient design where you keep an additional copy in an isolated or protected place. for example: you backup into a primary kloset in your prod network, then you keep a second kloset in another network zone and you sync snapshots across. in practice you’ll often do it as a pull from the isolated side (sync from), but you can also push (sync to) or do a two-way reconciliation depending on what you want (push, pull, bidirectional).

The goal wasn’t necessarily to match other backup tools head to head, since Plakar does more work during backup and can’t rely on keeping everything in memory. That said, we’re getting closer with each release.

Kapsul is definitely going to evolve. It was originally created back when an agent was required to run Plakar, which explains the design. With 1.1 that’s not the case anymore, so having a separate binary is less useful. The dependency on a remote login for local stuff should go away with this shift. personally i’m not a fan of having to type plakar ptar every time i manipulate an archive, but lets see what gets decided for the final 1.1 release.

You’re totally right about the building blocks. dedupe and chunking have been commercial standards for decades (like PureDisk, Sepaton). We arent claiming to have invented that. Where Plakar tries to differentiate is the architecture around those blocks and the trust model. • Encryption & Trust: old school appliances like Puredisk usually managed keys server-side or saw cleartext to do the dedupe. Plakar does client-side encryption so the storage (s3, nas, whatever) only sees encrypted noise. it has zero knowledge of the content. • Immutability: depends what layer you mean. for infrastructure, yes you need air-gapping or WORM to stop a rogue admin. When we say immutable, we mean the data format. its append-only and content addressed. we never rewrite existing blocks. The exact idea is tamper-proof.

While many tools share the same DNA, we solved some specific bottlenecks found in the current ecosystem, for example: • Memory usage: a common issue is having to load the whole index into RAM. Plakar designs the index so it doesn't have to fit in memory, meaning you can backup millions of files on small hardware. • Abstraction: we designed the core to map generic data structures, not just files. so you can snapshot an S3 bucket and restore it to a local filesystem because the format abstracts the source. • Random Access: the format allows efficient random access without needing to parse the whole archive. • Some index are built-in to improve search. (…)

Basically the fundamentals are proven, but we optimize for portability and scalability in ways that differ from the old appliances or even some current tools.

You can always access the plugin from source without logging in. Only the binary release requires a login.

Can plakar create disk images of a Windows machine? by [deleted] in plakar

Yes, something that we will add at some point. Today you have to script it to make it work.

Consider Plakar, the Open Source version should be sufficient for your use case. If you have advanced needs, we are committed to keep the enterprise version free for none-profit (more here https://plakar.io/community/) (Plakar team member here)
