Data segments and metadata segments to be stored in a storage system, where the data segments are deduplicated segments and each of the metadata segments includes a fingerprint for the corresponding data segment, for each of the metadata segments. It is determined that the metadata segment contains one or markers inserted by a client device of the storage system. The metadata segment is examined to determine whether the metadata segment satisfies a predetermined condition. In response to determining that the metadata satisfies the predetermined condition, the metadata segment is compressed using a predetermined compression algorithm. The compressed metadata segment is stored in the storage system, otherwise the metadata segment is stored in the storage system without compression. Thereafter, the data segments are stored in the storage system.
