Usually, we see this behaviour in the Artifactory storage section when a file(artifacts) exists in many places within an organization’s repositories, however, it is actually stored (binary) only once on physical storage. This happens due to the feature Deduplication in the Checksum-based storage.
Artifacts Size vs Binaries Size
Artifacts Size: The amount of physical storage that would be occupied if each artifact was a physical binary (not just a link).
Binaries Size: The amount of physical storage occupied by the binaries in your system.
Hence, Artifacts Size would be larger than Binaries Size sometimes when the same artifacts having multiple reference paths inside Artifactory repositories.
