[Samba] AD Backup in cron

[Stefan G. Weichinger]

I use Louis' scripts from https://github.com/thctlo/samba4 to backup my 
DCs per cronjob.

Can't remember when but I remember someone (Louis himself?) to notice 
that his backup script wasn't good enough anymore or something.

The Samba Wiki brings this:

https://wiki.samba.org/index.php/Back_up_and_Restoring_a_Samba_AD_DC

So what is the recommended way to automate this?

Run the command for the online-backup from a script, with the password 
in the script?

What is best practice here? Thanks in advance, Stefan
