What is the technique that involves distributing encrypted data across multiple storage solutions?

The technique that involves distributing encrypted data across multiple storage solutions is known as data sharding. This method breaks down large datasets into smaller, more manageable pieces, or "shards," which can be spread across multiple databases or storage locations. Each shard operates independently, allowing for improved performance, scalability, and security.

In a security context, sharding can enhance data protection, as even if one shard is compromised, the entire dataset remains secure because the actual data is fragmented and distributed. This approach also helps in efficiently managing encryption, as each shard can be encrypted separately.

Data redundancy typically focuses on creating copies of data to ensure availability and durability, but it does not inherently involve the distribution of encrypted data across different solutions. Bit splitting refers to a method of dividing a single piece of data into smaller parts at the bit level, which might not necessarily correspond to a distribution across multiple storage solutions nor involve encryption. Data encryption is simply the process of converting information into a code to prevent unauthorized access, but it does not imply distribution or management of data across various storage locations as described in the question.
