Immutable cold backups

Backups that ransomware cannot touch

Every backup is scanned for malware, stored immutable in the EU and restored in an isolated sandbox every month to prove it comes back.

What protects your backups

Everything that stands between an attacker and your last good copy.

Immutable storage

Object Lock keeps every backup unchangeable until its retention ends. Not even a stolen admin account can delete it early.

Malware scanning

ClamAV, entropy analysis and YARA rules check every upload. A suspicious archive is quarantined instead of stored.

Off-site replicas

Keep an independent copy in a bucket you control, or in LOX's cold archive in Warsaw, with a fast-access copy of the newest version.

Monthly restore tests

Once a month LOX restores your backups in an isolated sandbox and reports which ones really came back.

Audit log and legal hold

Every action is recorded in a hash-chained audit log, and a legal hold keeps a backup past its retention when you need it.

Restore any version

Download any version from the dashboard, the CLI or the API; the plugins restore a site in place.

How it works

A simple, secure process to protect your most critical data.

Step 1

Upload

A plugin, agent, SDK or the dashboard sends the backup.

Step 2

Scan and verify

Malware scanning and integrity checks run before anything is stored.

Step 3

Store immutable

The backup is written to the LOX vault with Object Lock and copied to your replicas.

Step 4

Test every month

Restore tests prove the backups come back.

True airgap protection

Offline backup storage

Sync your cloud backups to customer-controlled storage devices. Connect periodically, download new backups, then go offline for true airgap protection.

How airgap sync works

1. Connect

Plug in your NAS or device to your network. The LOX daemon authenticates securely with your account.

2. Sync

Automatically download all new backups since your last sync. Checksums verified for integrity.

3. Disconnect

Unplug and store your device offline. Your backups are now completely isolated from network threats.

Supported devices

Synology NAS

DSM 7.0+, native SPK package

QNAP NAS

QTS 5.0+, QPKG package

Raspberry Pi

ARM binary, systemd service

Linux Server

x86/ARM64, any distro

Ransomware proof: No delete API. Backups can only be downloaded, never modified or deleted remotely.
