如题,准备装r197了,准备好了uboot+r197+sp6,但备份这一块还不明白。那位老大给点指点吧。千恩万谢!!

到oesf的论坛上搜索zbackup,下载最新版本。
安装,使用前可以阅读一下zbackup,理解的尽量多一点。
1、备份最好退出X系统,在纯console界面上进行
2、命令:zbackup
3、要接上外接电源
4、备份数据放在SD卡上,要保证剩余空间

STATUS_XSCRSV=`pidof xscreensaver`

取消系统休眠,设置屏幕等
function set_dpms

}

恢复设置

fi
}

### begin
if [ "$1" = "-v" ] || [ "$1" = "-version" ] || [ "$1" = "--version" ]; then
echo "`basename $0` v$version ($VERSION)"
exit 0
fi

设置文件名和路径
if [ -f /media/realroot/sbin/init ] || [ -f /media/fakeroot/usr/sbin/cfdisk ]; then
if [ "`mount|grep data`" != "" ]; then
LOC=/data
else
LOC=/mnt/card

else
LOC=/mnt/card
NAME=initrd.bin
fi

if [ "$1" != "" ] && [ -d $1 ]; then

检查SD卡的剩余空间

if [ $? -eq 1 ]; then
echo "SD card not mounted! Exiting."
exit 1

检查硬盘的剩余空间

echo "There is only $[FREE_HDD/1024] MB available on /data!"
exit 1
fi
fi

if [ ! -d $LOC ]; then

开始备份了
echo "backing up $VERSION..."

do
if [ "`grep /mnt/$i /etc/directories`" = "" ]; then

done

/etc/rc.d/init.d/mntloop stop 2>/dev/null
if [ "`pidof X`" != "" ]; then
set_dpms

检查是否接上了外接电源
apm|grep "On-line" &> /dev/null
if [ $? -eq 0 ]; then
echo ""
echo " AC adapter is connected."
echo ""
else
echo ""
echo " AC adapter is NOT connected!"
echo "Please plug in to power source as backup may take over an hour..."
echo ""
fi

开始备份
echo ""
echo "Started backup at `date`"
echo "... please wait ..."

if [ -f /media/realroot/sbin/init ]; then
tar czf $LOC/$NAME /bin /etc /home /lib /root /sbin /usr 2>/dev/null
else
if [ -f /media/fakeroot/usr/sbin/cfdisk ]; then
cd /media/fakeroot
tar czf $LOC/$NAME /bin /etc /home /lib /root /sbin usr 2>/dev/null
cd -
fi

if [ ! -d /mnt/backup ]; then
mkdir -p /mnt/backup
fi

if [ "`mount|grep usr`" != "" ]; then
umount /usr 2>/dev/null
fi

建议loop文件
mount -t squashfs -o loop /home/.rootfs.squashfs /mnt/backup

装载loop文件
for i in bin home root etc lib sbin usr
do
mount --bind /$i /mnt/backup/$i
done
tar cf $LOC/home_custom.tar /home/root/ 2>/dev/null
mount --bind $LOC/home_custom.tar /mnt/backup/root/.home_default.tar

建立jffs2文件系统
mkfs.jffs2 -n -e 16 -o $LOC/$NAME.jffs2 -d /mnt/backup

umount /mnt/backup/root/.home_default.tar
rm $LOC/home_custom.tar
for i in bin home root etc lib sbin usr
do
umount /mnt/backup/$i
done

if [ -d /media/fakeroot/usr/bin ]; then
mount --bind /media/fakeroot/usr /usr 2>/dev/null
fi

加initrd的文件头
cat /mnt/backup/.initrdheader $LOC/$NAME.jffs2 > $LOC/$NAME

rm $LOC/$NAME.jffs2
umount /mnt/backup
echo ""
echo "Warning: the generated initrd.bin file may not work if the size of your root partition is less than 100MB."
echo ""
fi

备份完毕
echo "Done! - backup finished at `date`"
echo " - backup file is $LOC/$NAME"
echo " "

恢复设置
/etc/rc.d/init.d/mntloop start 2>/dev/null
if [ "`pidof X`" != "" ]; then
reset_dpms
fi

关于zbackup还有个问题,zbackup生成的是initrd.bin文件,是在sharp原厂的OK模式下用的,在uboot的emergency模式下也能用吗,emergency模式下不是用的rootfs.img吗,initrd.bin怎么用呢?
请老大指点?

那要分析rootfs.img是什么格式?

这个我完全不懂啊,怎么分析呢?分析完了又该怎么做呢?用zbackup做的initrd.bin怎么能在u-boot中刷机呢?愿闻其详,多谢指导!!!
