Server Replication (again) 1

[m1bzm]

Hi all,

I read a few threads on this subject a few weeks ago. Can anyone answer this one for me?

Im would like to use this tar commmand:

tar -cplzf backup.tar.gz . --exclude backup.tar.gz

to backup my box but am I correct in understanding that it will only backup the "/" partition and not the "/boot" "/home" etc.

Thank you for your help.

HI,
Well I you can try the crontab.Go to 'Super user scheduled tasks' and add a command there to backup your file then simply write down the time at which it shoud backup and that's it.The crontab will automatically back it up for you.

Hi Krischrist

LOL your one step ahead of me because that was going to be my next question...

Im trying to work out how to backup the individual partitions to a file. Ive tried backing up the whole server to a file but the file size gets too big and the tar command fails :-(

Ill set up the scheduling as soon as I can work out the correct commands.

Thanks for your help..

tar -cplzf backup.tar.gz . --exclude backup.tar.gz

the "l" tells tar to stay in one filesystem only. it also stops tar from trying to tar up things you don't want, like /proc and /mnt.
you could do
tar -czf backup.tar.gz / --exclude "/proc/*" --exclude "/mnt/*"
to get it to cover all filesystems while still missing out stuff you don't want. the quotes "" are important in this case.

if you are tar'ing straight to tape then consider taking out the "z" for zip and find out if your tape drive does hardware compression since it will be better/faster.

this command also creates the tarball in "/" which might not be a good idea. it looks like an example i wrote so sorry if i misled. the "p" may not be needed either (i can never remember, it doesn't hurt tho but if you restore the backup make sure the "p" is there as it keeps all the file permissions.

Hey thanks all - Ive got it going with all your help

This is part of the cron job and at the moment it works great. It takes a gziped tarball of all the important files and ftps them offsite.

====autobackup and ftp off site script===
tar -cplzvf /root.tar.gz . --exclude root.tar.gz
ftp -v -n ftp.server.com << SCRIPT
user USERNAME PASSWORD
put /root.tar.gz /home/backup/root.tar.gz
quit
SCRIPT
rm /root.tar.gz
tar -cplzvf /boot/boot.tar.gz /boot --exclude boot.tar.gz
ftp -v -n ftp.server.com << SCRIPT
user USERNAME PASSWORD
put /boot/boot.tar.gz /home/backup/boot.tar.gz
quit
SCRIPT
rm /boot/boot.tar.gz
etc....
=========================================

Thanks MrTom!
