innodb_log_file_size参数配置导致xtrabackup备份失败

用xtrabackup做mysql库的增量备份时报错如下：
xtrabackup:   innodb_log_file_size = 5242880
InnoDB: Error: log file ./ib_logfile0 is of different size 0 524288000 bytes
InnoDB: than specified in the .cnf file 0 5242880 bytes!
innobackupex: Error: The xtrabackup child process has died at /usr/local/xtrabackup/bin/innobackupex line 2631.

解决方法：
在--defaults-file=/tmp/my.cnf 指定的配置文件里设置innodb_log_file_size值如下：
innodb_log_file_size=524288000

再次备份提示
innobackupex: Error: Failed to create backup directory /tol/backup/incremental_one: File exists at /usr/local/xtrabackup/bin/innobackupex line 3883.

删除相关目录：
[root@goolen ~]# rm -rf /tol/backup/incremental_one

再次备份成功：
[root@goolen ~]# innobackupex --user=backup --password=backup --socket=/tmp/mysql.sock --defaults-file=/tmp/my.cnf --incremental /tol/backup/incremental_one --incremental-basedir=/tol/backup/full --no-timestamp --parallel=2
