well my linux box is configured to backup by Mondo Archieve.
My problem is that i am not familiur with linux so as Mondo, I am handling this box as additional stuff in my job. Recently my tape drive stops working due to some mechenical problem. Now we are not using tape drive anymore and there is no backup of my linux box which is really a ALARM for me. tell me what should i do now. how i check mondo configurations. can i store backup on Network path as i have a powerful server in my network with more then 100GB spare space on HDD. how i can do it. also i need to know which file should be backup i am running squid, intranet website, samba, gnokii on this linux box

You can make backup using various commands. To make a full backup of entire system use dump command.

Each Sunday night full backup
Following command backups all user data stored in /home, /var/www is web root for web sites and /etc is configuration directory. I use tar command to backup all important directories:

Code:

tar  -zcvf /backup-22-04-2006.tar.gz /var/www /home /etc

Then I run ftp data and store it to NAS server.

Rest of weekdays I just make an incremental backup and than again ftp to NAS server:

Code:

tar -g /var/tar.inc.log  -zcvf /backup-23-04-2006.tar.gz /var/www /home /etc

I also dump mysql data using mysql dump command.

mysqldump -u madmin -h localhost -p mypassword db1 | gzip -9 > db1.gz

And I upload this backup to NAS using ftp

Backup arranged as follows:
Full-backup == Sunday backup
System-backup = everyday incremental backup for both MySQL and directories

Code:

drwxr-xr-x   5 ftpusers ftpusers      4096 Aug  6 00:14 full-backup
drwxr-xr-x  34 ftpusers ftpusers      4096 Aug 10 00:15 system-backup

If you goto full-backup you will see data arranged according to dates

Code:

drwxr-xr-x   2 ftpusers ftpusers      4096 Aug  6 00:15 06-08-2006
drwxr-xr-x   2 ftpusers ftpusers      4096 Jul 28 06:17 28-07-2006
drwxr-xr-x   2 ftpusers ftpusers      4096 Jul 30 00:19 30-07-2006

The entire procedure is automated using shell scripts. Chk out my two scripts:

MySQL backup -
http://bash.cyberciti.biz/backup/mysql-backup.bash.php

http://bash.cyberciti.biz/backup/mybackup.php

If you want i will upload the ftp automated backup script when i will get back to home

let me know...

After digging into my linux box i found that mondo is already configured on my machine for backup. you can see in /var/local/sbin/mondoarchieve

Code:

echo "New archive made, setting path"
PATH=/usr/local/bin:$PATH
export PATH

echo "Path set, running mondo"
### run mondo
mondoarchive -Ot -d /dev/st0 -T /tmp -F -l GRUB -f /dev/hda -E "/usr/pub /var/mdaemon /var/tars"
echo "Mondo ran, emailing the logs"
### trim the log and email me the log file
tail -200 /var/log/mondo-archive.log > /tmp/mondo-archive.stripped
mail -s "Mondo Archive Report" me@mydomain.com.au < /tmp/mondo-archive.stripped
rm /tmp/mondo-archive.stripped
/usr/bin/eject /dev/st0

can you please make me understand what is script is doing?

Code:

echo "New archive made, setting path" 
PATH=/usr/local/bin:$PATH 
export PATH

Set up path

Code:

echo "Path set, running mondo" 
### run mondo 
mondoarchive -Ot -d /dev/st0 -T /tmp -F -l GRUB -f /dev/hda -E "/usr/pub /var/mdaemon /var/tars"

It will NOT backup dirs - /usr/pub /var/mdaemon /var/tars to tape device /dev/st0. In other words, it will backup whole system excpets those dirs specifed by -E option. It will also backup your boot loader GRUB and stored on /dev/hda hard disk.

Code:

echo "Mondo ran, emailing the logs" 
### trim the log and email me the log file 
tail -200 /var/log/mondo-archive.log > /tmp/mondo-archive.stripped 
mail -s "Mondo Archive Report" me@mydomain.com.au < /tmp/mondo-archive.stripped 
rm /tmp/mondo-archive.stripped

It will send an email to you along with mondo archive log.

Code:

/usr/bin/eject /dev/st0

It will eject /dev/st0 i.e. tape cartridge.

Can you type (paste here) the output of following command:

Code:

mondoarchive -Ot -d /dev/st0 -T /tmp -F -l GRUB -f /dev/hda -E "/usr/pub /var/mdaemon /var/tars"

I think you said that your tape drive has gone bad.

It is trying to access the tape drive /dev/st0. So, may be you can change the code

Code:

mondoarchive -Ot -d /dev/st0 -T /tmp -F -l GRUB -f /dev/hda -E "/usr/pub /var/mdaemon /var/tars"

to

Code:

mondoarchive -Ot -d /backup -T /tmp -F -l GRUB -f /dev/hda -E "/usr/pub /var/mdaemon /var/tars"

and then, as Vivek said, ftp the backup to another system or your NAS( if you have one)

Err ricc, i did not noticed about her/his bad tape... anyways i think following command need to change -Ot means tape for directory you should use -Oi (ISO)

Replace

Code:

mondoarchive -Ot -d /backup -T /tmp -F -l GRUB -f /dev/hda -E "/usr/pub /var/mdaemon /var/tars"

With:

Code:

mkdir /backup
mondoarchive -Oi -d /backup -T /tmp -F -l GRUB -f /dev/hda -E "/usr/pub /var/mdaemon /var/tars /backup"
