backing-up?

Hi!

How do you back-up your custom "trimmed" install onto a partition in case you have a system compromising situation ? it's possible to automatically start a copy, in case something goes wrong? if you please give a few "key" words for me to look for, as this might be a rather general question, and this is not the place to do it anyway, i would surely apreciate.
I am trying 3d acceleration on a IGP radeon 340M under slackware 9.1 (i found it in linux questions answers (see the duality of it?) thats why i love this site and go crazy about having to re-install everything again too!!) thanks !

You can backup kernel + modules + prog for your card + config files in a tar gz file which could be burned on a cd.

Code:

# mkdir backup
# cp -r /boot backup/
# cp -r /lib/modules/$(uname -r) backup/
# mkdir backup/bin
# cp whatever_programs backup/bin/
# mkdir backup/etc
# cp whatever_config_files backup/etc/
# tar -czvf backup.tar.gz backup

thanks a bunch !

one more thing :

i just used / for both is it alright?

# cp whatever_programs(/) backup/bin/
#cp whatever_config_files(/) backup/etc/
-------------------------------------------
ls /root/backup

2.4.22 boot etc

can i copy as well to a empty partition?
thanks again

If I understand, you just add slash (/) to end of file/directory name ? Is does not matter

yes, I tought burn resulting tar.gz backup file in a cd was more handy, but you can copy this file to everywhere you want.

For duplicate a entire partition to another partition, there is a command with tar :

Code:

cd /original_partition; tar cvf - . | (cd /destination_partition; tar xvf -)

Just make sure the destination partition is greater or equal than source partition

[edit]
The size partition does no matter but the size of files which are copied yes.
ie : a 8 gb / partition with 2 gb datas > just 2 gb are copied

I dont want to overask but, how can i activate the backed-up files? Sorry for all the questioning but you saved me a lot searching/reading !

To uncompact tar.gz file (?) : tar xzvf your_file.tar.gz
