Hi @AneeshBabu

Yes, `--decompress-threads` is a a valid flag for xtrabackup (See [docs](https://docs.percona.com/percona-xtrabackup/8.0/xtrabackup_bin/xbk_option_reference.html#-decompress-threads)).

As for `--parallel=16`, you may need to use copy-back as well for it to work, because that’s used for copying the files back to the datadir. (See [docs](https://docs.percona.com/percona-xtrabackup/8.0/xtrabackup_bin/xbk_option_reference.html#-parallel)).
