create 3 copies of the files, on 2 different media, with 1 off-site copy. Encrypted External Hard Drives. Use external hard drives for backup. For greater security, use software like BitLocker or FileVault to encrypt the entire disk. Then use NAS, a sort of private cloud, and Air-gapped Offline Media. Physically disconnect the hard drive from the computer after the backup. This protects the data from ransomware
BitLocker is a Windows security feature (Pro/Enterprise, and sometimes Home) that encrypts your entire hard drive to protect your data from unauthorized access, especially if your device is lost or stolen. It uses the AES algorithm (usually 128- or 256-bit) to encrypt data and requires a recovery key for access in the event of hardware changes or authentication issues.
FileVault is the disk encryption feature built into macOS that protects sensitive data by encrypting the entire startup volume. It uses the XTS-AES-128 algorithm with a 256-bit key to make files inaccessible without the user password, which is essential to MacBook security, especially in the event of theft.
NAS (Network Attached Storage) is an intelligent storage device connected to the local network (LAN or Wi-Fi), equipped with its own CPU, RAM and operating system, which allows multiple users to centralize, share and protect data (files, photos, videos, backups) in a secure way and also accessible remotely.
Ransomware is a type of malware (malicious software) that infects computers or networks, encrypting files and making them inaccessible. Attackers demand a ransom in cryptocurrency to unlock them. It represents a serious form of digital extortion, often threatening the disclosure of the stolen data.
