RANSOMWARE SURVIVAL

Backups that ransomware can’t touch

Your backups lock the moment they're made. No one can change them. Not hackers. Not even you.

Every backup vendor promises recovery. None prove it daily. Rediacc does.

THE PROBLEM

Ransomware targets your backups first

Picture this. It's 3 AM and ransomware just hit. You reach for your backups, and they're encrypted too. Here's why: attackers hunt down your backups first. In fact, 94% of ransomware victims had their backups targeted during the attack (Sophos 2024). If a backup can be changed, it will be. You need backups that lock shut the second they're made.

Revenue at risk based on $9,000/min avg downtime cost (Splunk/Oxford Economics 2024) [4]. Recovery labor: 6 engineers × recovery hours × $200/hr blended rate. Reputation cost estimated as a percentage of direct costs (industry estimate). With Rediacc: immutable snapshots restore in under 5 minutes — downtime approaches zero.
HOW IT WORKS

One command. Total protection.

1

Back up

Run rdc repo push production --immutable. Your data is saved and locked right away.

2

Lock

The lock happens in the storage layer itself. No changes allowed. Not by ransomware. Not by an admin with the top password.

3

Recover

When disaster hits, your clean backup is ready. Your whole setup is back in under 5 minutes.

UNDER THE HOOD

Why ransomware can’t encrypt these backups

Rediacc saves your data with btrfs, an open-source storage system built into Linux. It takes a read-only copy, a frozen snapshot of your files at one moment. Once that copy is sealed, the storage layer itself blocks any change. This isn't a software lock that malware can pick. Even with the top admin password, ransomware can't encrypt, change, or delete a sealed copy.

Traditional backup tools
Rediacc (locked in storage)
Software 'locks' that an admin password can switch off
Read-only copies guarded by the storage layer, safe even with the top admin password
Backups sit as normal files on disk, easy to find and encrypt
Copies live in the storage layer, hidden from regular malware
'Backup completed' is the only proof you get
We copy, boot, and health-check it daily, so it's truly verified
Full copy each time: 380 GB × 30 days = 11.4 TB of storage
Shortcut copies: 30 daily backups share data (~40 GB total)
WHY IT MATTERS

What you get

Write once, read forever

No one can change, delete, or encrypt your backups. Not hackers. Not a hacked admin account. Not ransomware that grabbed the top admin password.

No trust required

Even a hacked admin account can't touch a sealed backup. We test every backup automatically, every day. If one fails, you get an alert before it matters.

Instant verification

We restore every backup to a test copy and check it works. Not just a 'backup done' message. We actually prove it, every day.

THE GAP

The only backup locked in the storage layer itself

Other backup tools promise locked backups using software locks. Ransomware can pick those locks. Rediacc builds the lock into the storage layer, where ransomware can't reach.

We got hit with ransomware at 3:17am on a Saturday. The attackers encrypted 14 servers including our backup repository — or so they thought. Rediacc’s immutable snapshots were untouched. By 3:24am all 14 servers were restored from sealed backups. Total data loss: zero bytes. Total ransom paid: zero dollars.
