Issue Description
Galax backup failed.
Alarm Information


Handling Process
1 Using ‘dos2unix’, restore file type of‘logparam.conf’
2 Coppy this file to all CNA node
Root Cause
When checking MCNA system operate logs, we found someone have operation on MCNA at the day system backup failed. A file was replaced and the files type was changed.
Although content is the same except ‘clientLogExpireDay’, but using diff command, we could  see all lines different.

Using file command, we found files type is different.

From symptom above,we can image that the administrtor want to change ‘clientLogExpireDay’, so he download file ‘logparam.conf’, edit it using windows notepad and then upload it. This process lead to file type changed and system can not read this file. This file contend essential paameters especially ftp server password. So the backup process can not read ftp password and lead to galax backup failure. 
Do not edit linux files in windows system, it may lead to file type changed and have impact on services rely on this file.
