I am running x32 ubuntu 14.04 headless server. My wish is to do two different auto backups every monday at midnight. I just want to make sure I am making the correct steps, and not screwing my machine up at the same time. My goal is to:
-duplicate the contents of dir A into dir B
-duplicate the contents of dir C into dir D
-do this every monday at midnight (as in 00:00:59 Monday)

I'm under the understanding I need to write a script, so:
#!/bin/sh
# Monday Data Backup
sudo rsync -avucz --update --progress --human-readable /media/osstorage/ /media/osbunker/ && sudo rsync -avucz --update --progress --human-readable /media/storage/ /media/bunker/

I'd then save that script as "mon_sync_cron", and place it in /home/backup/script. This would be followed by "sudo chmod +x /home/backup/script/mon_sync_cron.sh"

next, I'd have to add the following to "sudo crontab -e"
0 0 * * Mon /home/backup/script/mon_sync_cron.sh


Is this all correct?
