Content Addressable Storage

Content Addressable Storage (CAS) is a data storage method where each piece of data is identified by a unique code generated from its contents, rather than a traditional location or filename. This code, often called a hash, acts like a digital fingerprint. When you want to retrieve data, you provide the hash, and the system finds the exact match. This approach ensures data integrity, avoids duplicates, and makes searching efficient. CAS is commonly used in backup systems, archiving, and scenarios where accurate, rapid data retrieval and verification are critical.
