Relica is designed without compromise for security, flexibility and ease-of-use.
All your data is encrypted locally using a password that only you know. It never leaves your computer unencrypted. No one else can read your backups, not even us.
Your data never leaves your computer without encryption, ensuring complete privacy. With Relica, you are a customer, not a product. We will never sell your information.
With a single subscription, you can back up any number of computers. Whether you're backing up your home computer or your organization's entire network, Relica scales with you.
Relica uses deduplication and incremental backups to minimize transfer times. Only changed data is uploaded, making subsequent backups incredibly fast.
Choose from 50+ cloud providers including AWS S3, Backblaze B2, Wasabi, Google Cloud, Azure, and more. Use your own accounts or our Cloud Escrow service.
Works on Windows, macOS, and Linux. The same familiar interface everywhere, so you can protect all your devices with ease.
Powered by Restic, a battle-tested open-source backup engine. Your backups aren't locked to our platform - you can always access them directly.
Every backup creates a point-in-time snapshot. Browse and restore any version of your files from any point in your backup history.
Set your backup schedule once and forget it. Relica runs quietly in the background, protecting your files without interruption.
