c、使用tar格式远程增量备份时收到如下提示，即只支持xbstream
xtrabackup: error: streaming incremental backups are incompatible with the
'tar' streaming format. Use --stream=xbstream instead.
d、用流备份，默认的临时目录都是系统的/tmp目录，需要保证该目录有足够的空间，或指定--tmpdir选项
e、流备份日志输出
innobackupex --stream=xbstream /tmp 2>>"$backupLog" | gzip > "$backup_file" 2>>"$backupLog"
