linux下使用extundelete恢复误删除的文件

34tg

一：搭建模拟环境

[iyunv@pan-T ~]# fdisk l#/dev/sda4为新添加的硬盘

Disk /dev/sda: 21.5 GB, 21474836480 bytes

255 heads, 63 sectors/track, 2610 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00009fb4

Device BootStartEndBlocksIdSystem

/dev/sda1*1256204800083Linux

Partition 1 does not end on cylinder boundary.

/dev/sda225615301024000083Linux

/dev/sda315301791209715282Linux swap / Solaris

/dev/sda417912052209651483Linux

[iyunv@pan-T ~]# mkfs.ext4 /dev/sda4#格式化硬盘

[iyunv@pan-T ~]# mkdir /tmp/sda4 #创建挂载点

[iyunv@pan-T ~]# mount /dev/sda4 /tmp/sda4/ #挂载新硬盘

[iyunv@pan-T ~]#cp -r {/etc/hosts,/etc/passwd} /tmp/sda4/

[iyunv@pan-T ~]#cd /tmp/sda4/

[iyunv@pan-T sda4]# mkdir -p a/b/c/d

[iyunv@pan-T sda4]#cp /etc/passwd . /a

[iyunv@pan-T sda4]#cp /etc/passwd ./a/b

[iyunv@pan-T sda4]#cp /etc/passwd ./a/b/c

[iyunv@pan-T sda4]#cp /etc/passwd ./a/b/c/d

[iyunv@pan-T sda4]#mkdir /tmp/back

[iyunv@pan-T sda4]#cp r ./* /tmp/back

[iyunv@pan-T sda4]#rm rf ./*

[iyunv@pan-T sda4]#cd

[iyunv@pan-T ~]#umount /tmp/sda4

[iyunv@pan-T ~]#

二、安装恢复软件包extundelete包

[iyunv@pan-T ~]#tar -jxvf extundelete-0.2.4.tar.bz2 -C extundelete #解压缩到extundelete目录中

[iyunv@pan-T ~]#cd /root/extundelete/extundelete-0.2.4

[iyunv@pan-T extundelete-0.2.4]# yum -y install e2fsprogs e2fsprogs-devel

[iyunv@pan-T extundelete-0.2.4]#./configure

[iyunv@pan-T extundelete-0.2.4]#make && make install

三、通过extundelete软件恢复测试文件

[iyunv@pan-T extundelete-0.2.4]#cd

[iyunv@pan-T ~]#cd /root/test #切换到已经创建好的test目录中进行恢复操作

[iyunv@pan-T ~]#extundelete /dev/sda4 --inode 2 #通过inode查看被删除的文件

[iyunv@pan-T test]#extundelete /dev/sda4 restore-all #恢复所有文件

[iyunv@pan-T test]#extundelete /dev/sda4 restore-inode 12 #通过inode号来恢复文件

[iyunv@pan-T test]#extundelete /dev/sda4 restore-file passwd #通过file文件名来恢复文件

var kevent = 'onabort|onblur|onchange|onclick|ondblclick|onerror|onfocus|onkeydown|onkeypress|onkeyup|onload|onmousedown|onmousemove|onmouseout|onmouseover|onmouseup|onreset|onresize|onselect|onsubmit|onunload'; var aevent = kevent.split('|'); jQuery('.showContent img').each(function(){ var nimg = this; jQuery.each(aevent, function(i, n){ if (n!='onload') { jQuery(nimg).attr(n, ''); } else { if (jQuery(nimg).attr(n) != 'if(this.width>650) this.width=650;') { jQuery(nimg).attr(n, ''); } } }); });
