[X-Newbies] Backing Up Files

[Christopher Collins]

OK, so maybe I will use this list, This is a bit of a newbie question.

I need to backup 2 hard disks to a single hard disk for a client. We  
have looked at all the backup programs and have settled on rsync  
because it will give us a readable copy of the files that we need to  
backup.

Now in Windows, I would create a batch file with the command I want  
and then use the inbuilt scheduler to run it at a specified time.

How do I do the same on a Mac? The OS is Mac OS X Server 10.4.11 and  
the backup is from 2 internal hard disks to an external hard disk.

We wanna run the "batch file" at 10pm at night every weekday. Not sure  
if this will be helpful, but the command lines will probably be:

rsync -auv /Volumes/Storage_1 /Volumes/External_1/Storage_1
rsync -auv /Volumes/Storage_2 /Volumes/External_1/Storage_2

If someone can give me some ideas about how to get pointed in the  
right direction with a basic idea, I can go and do some more  
searching.....

Thanks everyone!
