Abstract

A system and non-transitory computer program product for preserving data redundancy in a data deduplication system in a computing environment is provided. A selected data segment, to be written through the data deduplication system, is encrypted such that the selected data segment is not subject to a deduplication operation. Copies of the data segment that are to be precluded from data deduplication are determined and identified. A unique encryption key is used to encrypt the selected data segment to be written through the data deduplication system such that the selected data segment is not subject to a deduplication operation. The data deduplication system is tricked to recognize the encrypted, selected data segment as new, undeduplicated data by the encrypting thereby skipping steps of the deduplication operation that includes fingerprint generation and matching. The encrypted, selected data segment is directly written to a new physical storage location.
