用xtrabackup2.4备份mysql5.6.30一直显示log scanned up to

一直处于log scanned up to，只能ctrl+c强制终止备份





没有大事务

停止xtrabackup前



停止xtrabackup后



没事大事务，大概用了15分钟

xtrabackup: Transaction log of lsn (104012539342) to (104012560503) was copied.
170420 17:31:43 completed OK!

real 15m18.319s
user 12m48.151s
sys 0m11.271s

因为用了gzip压缩，机器配置比较低导致gzip的cpu使用率是96%

一般170420 17:04:16 >> log scanned up to (441263433482)
后面的这个数字441263433482有变化就不用担心，如果后面这个数字没有变化，表示xtrabackup进程被hang住了，可能有大事务需要注意
