 Posted: Fri Aug 24, 2007 10:03 pm Post subject: [SOLVED] backup the / with tar |
 |
|
after i finished installing gentoo on my laptop i noticed a big problem, the only way i can install back windows is by dvds of recovery that have good probability of formating the disk where the gnome is installed,
since that i want to backup using tar like "creating" a stage that we use to install gentoo,
the question is what should the command be...
i already searched but i must confirm with someone before i loose to many hours of work
| Code: |
tar -cvWpf file.tar /mount/point |

while in the live system, run the following commands.
| Code: | | tar cvjp --exclude=/dev --exclude=/sys --exclude=/proc --exclude=/stage4.tar.bz2 --file /stage4.tar.bz2 / |
to restore the stage4 tarball from a livecd, just untar it to /mnt/gentoo then perform the following commands.
| Code: | | cd /mnt/gentoo && mkdir dev proc sys && cd dev && MAKEDEV generic |
after just emerge -e system; compile your kernel, then setup your boot loader etc.. that should be all. |

DaNe,
Search the forums for a Stage 4.
Thats the name given to what you want to do.

DaNe,
You need not rebuild the kernel provided /boot was mounted when you made the stage 4.
You may need to reinstall grub to the MBR, depending on what happens to the disk space outside of the filesystem.
It will not survive if you reinstall Windows. That will install the Windows boot loader.

I found a nice script that takes care of nearly everything for me. I have a separate /backup partition located on a hard drive from my operating hard drive and store all of my files there.
/backup/backup
| Code: | #!/bin/bash
# the configuration file script...run this to make a backup

#############################################
# configuration is in backup.cfg
# get config
. /backup/backup.cfg
#set -x
# some helper functions
backupdir()
{
ARCHIVE_NAME=$1-`$dateformat`.tgz
echo "Building $1 archive"
tar cfz $target/$ARCHIVE_NAME /$1 > /dev/null 2>&1 && echo "[got it!]" || echo "[FAILED]"
}
delold()
{
echo "Deleting old backups"
rm $target/*.tgz
}
makebigfile()
{
echo "Create archive of all backups"
tar cf $target/backup-`$dateformat`.tar $target/*.tgz
}
# main script
# do we need to delete old stuff
if [ "$delold" = "yes" ]; then
delold
fi
# backup all needed dirs
for i in $backupdirs
do
backupdir "$i";
done
# make big file, if required
if [ "$bigfile" = "yes" ]; then
makebigfile
fi |
/backup/backup.cfg
| Code: | # the configuration file script...run this to make a backup
#
# Author: Stefan Wendler

#############################################
#
# define which dirs to backup
# backupdirs="bin boot dev etc home lib opt root sbin usr var"
backupdirs="bin boot etc lib opt root sbin usr var"
# define where to store the backup
target="/backup/"
# bigfle yes | no
bigfile=no
# del old backups
# delold yes | no
delold=yes
# dateformat
dateformat="date +%G-%m-%d" |
Just run ./backup after setting up the configuration file and you're good to go. |
