Q: Rsync, Batch: How to avoid the "password" ask ?

[bzels123]

Hi

As I want to automate my Desktop backup process, I'm currently trying
to finilize a CMD (Windows XP batch) file in order to save different data
(outlook.pst, \desktop, \docs, \Favorites ....).

My problem is that even with this parameter SET RSYNC_PASSWORD=xxxx
It still ask me for a password, blocking of course all the process 
automation.

I'm running either on my Linux backup box (RedHat9 v2.40) or on my PC,
version 2.6.2 of rsync, assuming it is the latest.

Thanks in advance,

Regards,

Bart.
