What is variable length deduplication primarily designed to do?

Variable length deduplication is primarily designed to efficiently store data by identifying and eliminating duplicate chunks of information. The correct approach to variable length deduplication involves saving data as separate objects or chunks, which can vary in size. This method significantly enhances storage efficiency because it allows the system to identify and remove redundancies across various portions of data, regardless of their length.

When data is separated into variable-length chunks, the system can effectively manage and compress it, which leads to reduced storage costs and improved performance. This is particularly advantageous in environments where large amounts of data need to be stored, such as backups or cloud storage, as it helps optimize storage capacity.

The other options focus on characteristics that do not align with the purpose of variable length deduplication. Storing all data together in blocks lacks the nuance of chunking data efficiently, compressing data in fixed sizes misses the variable aspect that allows more flexible and efficient deduplication, and automatic encryption does not inherently relate to the deduplication process itself. Each of these alternatives ignores the primary intent of varying the size of the chunks to maximize storage efficiency.
