newbie - cron help

[panther89]

Hi,
I'm an Ubuntu newbie and i need help with some task.


I have a server and i'like to backup it daily. So i need some script, which do this task.

- daily at 00:00 connect to SSH
- download folders /www1 and /www4 from server and save them to disk (~/backup_YY-MM-DD) (and create todays folder, like backup_11-07-10) (through scp?)
- after all is backuped, shutdown PC


I'd like to study it myself, but i need backup server content quickly..


Thx for help, better script with short explain.

for any/all backups and uploads it is easy and best to use

rsync

write a simple bash script (test the commands manually in CLI first, then enter in your bash script)
using rsync commands to get all your folders backup'd
after ever backup add at the end of line a
; sync
to make sure all previous processes are finished and written to disk before proceeding (specially before shutdown)

all rsync by default is SSH
so I assume you have your server key authentication prepared to avoid any password need when doing cron jobs

after you have done above backup one by one manually and successfully
you then enter the path to your bash script in your cron entry

I do my own server backups that way since years - also the opposite . to synchronize my servers with all offline prepared new content

later when back up important, you will have time to study rsync - its easy and
