A backup you have never tested is just a hope

Built to survive ransomware

Modern ransomware groups know that backups are what let victims avoid paying. They actively look for backup systems and try to encrypt or delete them before launching the main attack. That is why a backup drive plugged into the same network, using the same administrator password, offers far less protection than most owners assume. If an attacker can reach it with stolen credentials, they can usually destroy it too.

Resilient backup follows a simple principle: keep multiple copies, on different types of storage, with at least one copy offsite and protected from tampering. Immutable or isolated backups that cannot be changed or deleted for a set period, even by an administrator account, give you a reliable recovery point if your main environment is compromised. Separate credentials and multi-factor authentication on backup systems add further protection.

Cloud applications need attention too. Services like Microsoft 365 are highly available, but their built-in retention is not the same as an independent backup you control. Accidental deletions, malicious insiders, and compromised accounts can all remove data that you later discover you need. A dedicated backup for email, OneDrive, SharePoint, and Teams closes that gap and makes it easy to restore a single message, file, or entire mailbox.
