# xtrabackup --decompress --target-dir=/data/compressed xtrabackup version 2.4.8 based on MySQL server 5.7.13 Linux (x86_64) (revision id: 97330f7) 170921 14:04:52 [01] decompressing ./xtrabackup_logfile.qp sh: qpress: command not found cat: write error: Broken pipe Error: thread 0 failed.
原因是decompress解压缺少工具qpress解压办法：
# wget http://www.quicklz.com/qpress-11-linux-x64.tar # tar xvf qpress-11-linux-x64.tar # cp qpress /usr/bin
安装好qpress后就可以正常解压了！
