Why immutable backups are non-negotiable for dental practices

Most backup tools promise protection. Far fewer can promise that the backup itself can't be tampered with — and that gap is exactly where modern ransomware lives.

The problem with mutable backups

If your backups live somewhere an administrator account can reach and modify, then anyone who compromises that account can do the same. Attackers know this. The first thing sophisticated ransomware does is find and corrupt the backups, then encrypt production. By the time you reach for your recovery point, it's already gone.

What "immutable" really means

An immutable backup is written once and locked for its full retention window. Not by policy — by design. No credential, no admin, no insider, and no malware can alter or erase it.

At DDSArk, every recovery point is content-addressed and sealed the moment it lands. We then replicate it to a second, independent provider, so a single outage — or a single compromised account — never puts your history at risk.

The test that matters

Ask your current provider one question: "If an attacker gets domain admin tonight, can they delete our backups?" If the answer isn't a flat no, you don't have immutability. You have hope.
