Write Once Read Many

Write once read many (WORM) is a data storage method that allows data to be written to a storage medium only once. After the initial write, the data cannot be modified or deleted. However, the data can be read multiple times.

Object storage, including cloud storage, is compatible with write once read many capabilities.

Key characteristics of WORM:

• Immutability: Data is locked in place after being written.
• Data integrity: Protects data from accidental or malicious changes.
• Security: Helps prevent ransomware attacks as data cannot be encrypted or held hostage.
• Compliance: Meets regulatory requirements for data retention and preservation.
