Yes. At least on my server (Banana Pi), BackupPC_zcat is four times slower than either zlib or pigz. As the number of errors of this kind is usually really small, it's still faster to re-check the errors than using BackupPC_zcat for all the files. But one should test it for their server and select the best option, taking into account the balance between CPU, memory and disk. Regards, Guillermo
