Audited encryption
End-to-end encryption whose cryptography was reviewed in an independent audit.

Assume they get in.
Recover anyway.
Attackers go after backups first. Plakar keeps encrypted, tamper-evident snapshots they cannot read or silently alter, plus an off-site copy at another provider, so your disaster recovery plan holds when it matters.
The problem
Ransomware goes after your backups first.
If an attacker can read, encrypt, or delete your backups, you do not have a recovery plan. You have a negotiation.
Backups in the same blast radius
Backups reachable with the same credentials as production fall with production. One compromised admin account is enough to wipe both.
Readable backups are a second breach
Unencrypted backups hand attackers a full copy of your data to exfiltrate and leak, even after you have restored.
Restores nobody has tested
Backups that were never verified or restored fail in the middle of the incident, when it is too late to fix them.
How it works
Encrypt, verify, isolate, recover.
Four layers between the attacker and your last good snapshot.
-
01
Encrypt at the source
Data is chunked, deduplicated and encrypted before it leaves your environment. Storage only ever holds ciphertext, and passphrases live in your Control Plane or your own secret manager.
-
02
Detect any tampering
Every snapshot is signed and every chunk carries a MAC, so any change is detected. A check task can run after each backup to prove the Kloset is intact.
-
03
Keep a copy out of reach
Sync snapshots to an off-site Kloset on another provider, account or storage tier, or export a self-contained, encrypted .ptar archive to keep offline.
-
04
Restore what you need
Browse any snapshot, download a single file, or restore a whole resource to its original location or an isolated one, so you can rehearse recovery without touching production.
Truly immutable? Plakar snapshots are never modified in place, and any change is detected. For immutability enforced by the storage itself, pair them with object lock, WORM, or an offline .ptar copy.
What you get
Built for the worst day, not the average one.
Tamper-evident snapshots
Signed snapshots and MACs, verified by check tasks after every backup.
Learn moreSecond copy with sync
Replicate a Kloset to another store, provider, or tier on a schedule.
Learn moreOffline .ptar archives
One encrypted, read-only file to store offline.
Learn moreLegal hold
Freeze a restore point so no one can delete or prune it through the Control Plane. Pair it with your storage's object lock.
Learn moreLeast privilege
Granular roles, enforced two-factor authentication, and Edges that open no inbound ports.

System State backups of your domain controllers, often the first thing to bring back.

Browse, download single files, or restore to a new target.

announcement
Agentless VSS and SQL Server backup now available in Plakar
VSS and SQL Server backups are now free for registered Plakar users: agentless over SSH, encrypted and deduplicated into an open, portable Kloset store. The connectors are closed source, built for Control Plane. Active Directory recovery is a Plakar Control Plane capability.
