数据库远程备份之前好好的，最近几次发现没备份到，报错

db.log的内容:
[/data/backup/DB_mt_20161013*.tgz] Delete Old Backup File
[/data/backup/DB_mt_20161018_02.tgz] Backup success
[/data/backup/DB_mt_20161020*.tgz] Delete Old Backup File
[/data/backup/DB_mt_20161025_02.tgz] Backup success

[/data/backup/DB_mt_20161108_02.tgz] Backup success
[mt] not exist
[mt] not exist

配置一直都没动，不知道为何出现这个错误，而且mt数据库也是存在的
 
 
 
这是tools/config_bakcup.txt里的内容
com:::[ ! -e /data/backup ] && mkdir -p /data/backup
file:::/data/backup/DB_mt_20161108_02.tgz /data/backup push
com:::[ -e /data/backup/DB_mt_20161108_02.tgz ] && rm -rf /data/backup/DB_mt_20161124_*.tgz
