Backnix

Linux server backup that survives the loss of the server

Your server holds application code, configuration under /etc, user uploads, certificates and logs you may need for an investigation. Backnix is designed to copy what matters to encrypted cloud storage on a schedule, so a broken disk or a compromised machine is a recovery task, not a disaster.

The problem

The problem: servers fail in ways RAID does not cover

RAID protects against a disk failure. It does not protect against deleted files, corrupted file systems, a failed distribution upgrade, a compromised account encrypting your data, or a provider closing your account. Snapshots taken by the same provider share the same fate as the server.

  • Human error

    A wrong command or a bad deployment can delete or overwrite data in seconds.

  • Security incidents

    Attackers who gain root access can modify or encrypt everything reachable from the server, including local backups.

  • Provider or hardware loss

    A data center incident or an account problem can make the server and its local snapshots unavailable at the same time.

The consequence

The consequence: rebuilding from memory

Without an independent backup, recovery means reinstalling the operating system, guessing configuration values, chasing old copies of certificates and asking users to upload their files again. Some data simply does not come back, and the outage lasts as long as the reconstruction.

The solution

How Backnix approaches server backup

A lightweight agent runs on the server, reads the paths you select and sends compressed, encrypted data to S3 cloud storage outside your infrastructure. After the first full backup, incremental runs transfer only what changed. Every run is recorded so you can see when the last good backup happened.

  • Select paths and exclusions

    Protect /etc, /home, /var/www, /srv or any path, and exclude caches and temporary files.

  • Schedule

    Run backups hourly, daily or at the time that fits your workload.

  • Encrypt locally

    Data is encrypted on the server before upload.

  • Verify and restore

    Check integrity and restore single files or complete directories.

Server backup flow: a server runs the Backnix agent, data is encrypted, sent to cloud storage, verified, and can be restored.
Server backup flow: Server → Backnix Agent → Encryption → Cloud Storage → Verification → Restore.

Benefits

Benefits

  • Offsite by default

    Backups live outside the server, the rack and the provider account that hosts it.

  • Less bandwidth

    Incremental transfers keep daily backups small after the first run.

  • Point-in-time history

    Keep several versions according to your retention policy and restore the one you need.

  • Clear status

    A missed or failed backup is visible instead of silently ignored.

Technical considerations

Technical considerations

File-level backups are ideal for configuration, application files and user data. For databases, back up a consistent dump instead of raw data files, or use the database backup option. Exclude virtual file systems such as /proc, /sys and /dev. Plan a restore procedure that includes reinstalling packages, because a file backup is not a bootable disk image. Windows Server support is planned and marked as coming soon.

Server backup FAQ

Which Linux distributions are supported?
The agent targets mainstream distributions such as Ubuntu, Debian, RHEL-compatible systems and their derivatives. Exact supported versions will be published with the agent release.
Can I restore a single file?
Yes, file-level restore is part of the design, so you do not need to download the whole backup.
Is Windows Server supported?
Not yet. Windows Server backup is planned and shown as coming soon on the features page.
Do I still need snapshots?
Snapshots are great for fast rollbacks. They complement offsite backups but do not replace them.
