How It Works — Silver Fox Cyber VaultShield

You choose what gets backed up

When you sign up for VaultShield, we install the Comet Backup client on your Windows or Linux computer. You select what you want protected:

📁 Files & Folders

Documents, photos, videos, spreadsheets. Everything in your chosen folders, backed up daily.

💿 Full Disk Image

A complete snapshot of your entire drive. If your computer is destroyed or encrypted, we can restore it to exactly the state it was in before the attack — applications, settings, and all.

Most home users choose Full Disk Image. It's the simplest option and provides the most complete recovery.

Your data goes to a private, dedicated vault

When you become a VaultShield client, we create a private, dedicated cloud storage bucket exclusively for you. Your data never shares space with another customer's data.

Before anything leaves your computer, the backup client does three things in sequence:

1
Deduplicates — only changed data is uploaded after the first backup. Incrementals are typically a small fraction of your total data size.
2
Compresses — using the zstd algorithm, typically achieving 2:1 or better compression. Less data uploaded = faster backups = lower storage costs.
3
Encrypts — with keys that only exist on your machine. We never see your unencrypted data. Nobody does.

The immutability lock — the part that matters most

When each backup object arrives at your storage vault, it's immediately stamped with an Object Lock retain-until date. This is enforced at the storage provider level — not by software, not by us, but by the underlying storage infrastructure itself.

What that means in practice:

✓ Ransomware that gains full access to your computer cannot delete your backups
✓ A criminal who somehow obtained your storage credentials cannot delete your backups
✓ Deletion requires explicit administrative authorization — it doesn't happen automatically, accidentally, or silently

Your daily backups are locked for their retention period (30, 90, or 365 days depending on your tier). Routine deletion by ransomware, hackers, or automated processes cannot override that lock. When backups expire naturally, storage is reclaimed automatically.

Recovery — choosing which day to go back to

When something goes wrong, recovery isn't complicated. You contact us, tell us what happened, and we work through the restore together.

🦠 Ransomware

We identify the last clean backup point. We restore your system to that point. You're back to normal.

🗑️ Accidental Deletion

You deleted something weeks ago and just realized you need it. We restore just that file or folder. Everything else stays as-is.

💥 Hardware Failure

Your hard drive dies. We restore your full disk image to a new drive. Your computer is exactly as it was before the failure.

After setup — you don't have to think about it

After the initial setup — which we walk you through — VaultShield runs silently in the background. There's no dashboard you need to check, no alerts to respond to unless something actually goes wrong, no monthly maintenance tasks.

The backup client runs on a schedule you set (we recommend 2:00 AM — it runs while you sleep), uploads only the changed data, and reports back to our monitoring system. If a backup fails three nights in a row, we'll reach out to you.

You don't need to understand deduplication, compression, retention passes, or Object Lock expiration. That's what you're paying us to manage.

Simple enough to explain in three minutes.
Serious enough to trust.
