The present disclosure describes a technique for performing an efficient deduplication of compressed source data. The techniques may reduce the required storage footprint required for deduplication of compressed data. In order to reduce the storage size required, the system may perform additional decompression/recompression processes by identifying particular compression algorithms used by a source storage system. Once the compression algorithm is identified, the system may initiate decompression and then perform fingerprint analysis of the segment in the file of the uncompressed data. When a recovery process is initiated, the system may recompress the deduplicated data using the same compression algorithm used by the source storage system. Accordingly, the data recovery process may be performed in manner in which the client device receives restored data as expected and in the original compression format.
