Cloudstic
Currently in early access

All your files. One encrypted backup.

Google Drive keeps your files in sync, but sync is not backup. One accidental delete and it's gone everywhere. Cloudstic creates encrypted, point-in-time snapshots you can always restore from.

The Real Risk

Sync is a Mirror, Not a Safety Net.

Cloud providers are excellent at protecting your data from disk failure, but they are powerless against human failure. Because sync is instantaneous, your mistakes are permanent.

The "Delete Everywhere" Trap

When you delete a folder on your laptop, the cloud doesn't say "Are you sure?" It says "Me too." If you don't notice a missing folder within 30 days, it's not just deleted - it's scrubbed from the planet.

The Risk

You aren't just one click away from losing a file; you're one sync cycle away from losing a decade of work.

Corruption Propagation

Ransomware doesn't just lock your local drive; it triggers a sync. Your cloud provider faithfully replaces your healthy documents with encrypted, unreadable versions across every linked device.

The Risk

Syncing isn't protection; it's a high-speed delivery system for data corruption.

The "Point-in-Time" Gap

Versioning in Google Drive works for a single file, but it fails for a system. You can't tell Google, "Revert my entire account to exactly how it looked at 10:00 AM last Tuesday."

The Risk

Without snapshots, you're forced to hunt for individual file versions manually - a process that takes hours and is prone to missing hidden dependencies.

RAID is not a backup. Sync is not a backup. Your 'Recently Deleted' folder is a countdown timer, not a strategy.

Content-addressed storage

Same file, stored once

If the same file exists on your Google Drive and your laptop, Cloudstic stores it only once. You save space and money.

Drive
OneDrive
Local
1 backup

3 sources, 1 copy of each unique file. No wasted storage.

Built for reliability

A content-addressed storage engine inspired by modern backup tools like restic. Fast, space-efficient, and crash-safe.

Incremental backups

Only changed files are stored. Each backup is fast and space-efficient, no matter how many sources you connect.

Cross-source deduplication

A file that exists on Google Drive and your laptop is stored only once. You only pay for unique data.

One-click restore

Download any snapshot as a ZIP. Browse your backup history, compare versions, and restore exactly what you need.

Set it and forget it

Connect your accounts and drives once. Cloudstic handles scheduling, retention, and cleanup automatically.

Security first

Your data is private. Period.

Everything is encrypted before it's stored. Each account has its own key. There are no backdoors, no shared secrets, and no way for us to read your files.

Encrypted by default

AES-256-GCM

Every file, every snapshot, every piece of metadata is encrypted before it's stored. Your data is unreadable without your key, even to us.

Your own encryption key

Per-account isolation

Each account gets a unique encryption key. One compromised account can never expose another. Keys can be rotated at any time.

Passwordless sign-in

Passkeys / WebAuthn

Sign in with your fingerprint, Face ID, or a hardware key. No passwords means nothing to phish, leak, or forget.

Breach-resilient

Defense in depth

Even if our servers were compromised, attackers would find only encrypted blobs and encrypted credentials. No plaintext, anywhere.

Open source

Don't take our word for it.

The backup engine that powers Cloudstic is fully open source. Inspect how your data is encrypted, chunked, and stored. Audit the code, run it yourself, or let us handle everything.

Let us handle it

Sign up and start backing up in seconds. We run the infrastructure, scheduling, and retention — so you don't have to.

Run it yourself

Install the CLI, point it at your own storage, and run backups on your terms. Same engine, full control.
