Here is a script i use to backup my .mp3s on a daily basis. When run it checks my source partition to make sure it is mounted, if it's not, it mounts it. Then it checks to see if my destination parition is mounted (my destination is a samba share on another box), if its not mounted it mounts it. Then it uses cp -R to copy the files over. you could use tar or gzip or whatever you wanted. I had it setup to use zip but that was just too slow and you really don't gain much when zipping .mp3s. After the copy is complete it checks to see wether or not it had to mount the source and destination and if it did have to mount them then it unmounts them. It also logs what is backed up.

Just drop something similar in /etc/cron.weekly, make sure it's executable, and you should be good to go.

I highly recommend the Advanced Bash Scripting Guide from TLDP (http://www.tldp.org).

thanks for ur quick reply voidinit

i really appreciated that...


i'll definitely look into the Advanced Bash Scripting Guide from TLDP that u have mentioned..that should be good for me to start with

hopefully i will be able to get it done by end of next week bcos it's productive server so i can't really leave it on it's own without any backup...
ideally. i would like to perform incermental backup (tar possible) for the /home /var ...it should be harder to implement ..well time will tell...

thanks again

cheers
