118
119 <p>In the past restoring to a different location was not supported by <b>Clonezilla Live</b> at all. Because of that, a script called <b>reloc-img</b> was added to <b>Clonezilla-SysRescCD</b>, which would help the user perform this task.</p>
120
121 <p>Recent versions of <b>Clonezilla Live</b> partly support restoring to a different location, so the <b>reloc-img</b> script is obsolete, and has been removed. <b>Clonezilla Live</b> now supports:</p>
122
123 <ul>
124 <li>Relocation of a disk image (restoring a whole disk)</li>
125 <li>Relocation of a partition image (restoring a partition)</li>
126 </ul>
127
128 <p><b>Clonezilla Live</b> does not support:</p>
129 <ul>
130 <li>Relocation of a single partition contained into a disk image.<br>
131 <br>
132 Imagine you have a disk backup image named <b>hda-2009-02-02</b>. The image contains three partitions, <span style="color: Red; font-weight: bold;">hda1</span> (operating system), <span style="color: Red; font-weight: bold;">hda2</span> (user data) and <span style="color: Red; font-weight: bold;">hda3</span> (other data).<br>
133 <br>
134 You want to restore your <b>other data</b> partition (<span style="color: Red; font-weight: bold;">hda3</span>), to a different system (partition <span style="color: Green; font-weight: bold;">sdb2</span>) but there is no way to restore (extract) a single partition from a disk image - you can only restore the whole disk.
135 </li>
136 </ul>
137
138 <p>In order to address this situation, two new scripts have been written for <b>Clonezilla-SysRescCD</b>: <b>imginfo</b> and <b>imgconvert</b>
139
140 <H2><a name="imginfo-script"></a>Script imginfo <span class="hideprint">[<a href="#reloc-img-top" title="go to top of the page">^</a>]</span></H2>
141
142 <p>The script will be used to print info about existing image files.</p>

161
162 <p>The script will be used to convert an existing <b>disk</b> or <b>partition</b> image file to a new <b>partition</b> image file.</p>
163
164 <p><b>imgconvert</b> can create two type of images:</p>
165
166 <ol>
167 <li><b>Temporary image</b><br>
168 This type of image is created by linking the data files of the existing disk image to the new partition image. This means that the original image <b>must</b> be present for the new image to be used. This is the default image type created by <b>imgconvert</b>.
169 </li>
170 <li><b>Permanent image</b><br>
171 This type of image is created by copying the data files from the existing disk image to the new partition image. This means that the original image is not needed in order to use the new one. Permenant image files are created using the command line parameter <b>-p</b>.</li>

198 <p>After booting into <b>Clonezilla Live</b>, I select<br>

222 <p><b>sys-bck</b> is a backup of my old system, which had three partitions.

350 <H2><a name="reloc-img-boot"></a>Booting a restored Linux system <span class="hideprint">[<a href="#reloc-img-top" title="go to top of the page">^</a>]</span></H2>
351
352 <p>A Linux system that has been restored to a new disk/partition, is usually not ready to be booted right after the restoration procedure is finished.</p>
353
354 <p>There are two more steps that you may have to take:</p>
355
356 <ul>
357 <li>Fix <b>/etc/fstab</b></li>
358 <li>Reinstall <b>GRUB</b>.<br>
359 I will assume GRUB is your boot manager, as it is the usual case nowadays.</li>
360 </ul>
361
362 <p>For this example I will assume that you have restored a Linux system (that used to be in <font color="Red"><b>sdb</b></font>), to a new disk (<font color="Green"><b>hda</b></font>), and that it contains three partitions, <b>/</b> (the root partition), <b>/home</b> (user's partition) and a <b>swap</b> partition. You must be really careful here, as the name of the new disk depends on the system to be booted. If it uses one of the newest Linux kernels (using the libata disk driver), ALL your disks will be recognised as SCSI. More info: "<a href="annex-a-devices.html#annex-a-scsi-ata">Identifying devices in Linux</a>" section "<a href="annex-a-devices.html#annex-a-scsi-ata">SCSI disks when there are none!!!</a>".</p>
363
364 <p>This is what we have:</p>
365
366 <p class="newcode">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;root partition&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;home partition&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;swap partition<br>
367 Old system&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font color="Red">/dev/sdb1</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font color="Red">/dev/sdb2</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font color="Red">/dev/sdb3</font><br>
368 New system&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font color="Green">/dev/hda1</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font color="Green">/dev/hda2</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font color="Green">/dev/hda3</font></p>
369
370
371 <H3><a name="reloc-img-boot-fstab"></a>Fixing /etc/fstab <span class="hideprint">[<a href="#reloc-img-top" title="go to top of the page">^</a>]</span></H3>
372
373 <p>Since we are still in <b>Clonezilla Live</b>, right after the restore procedure has finished, we will use it to mount our restored root partition, and edit its <b>/etc/fstab</b>. We issue the commands:</p>
374
375 <p class="newcode">mkdir /new-root<br>
376 mount /dev/hda1 /new-root<br>
377 vi /new-root/etc/fstab</p>
378
379 <p>The contents of <b>/etc/fstab</b> could be something like</p>
380
381 <p class="newcode"><font color="Red">/dev/sdb1</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;reiserfs&nbsp;&nbsp;&nbsp;acl,user_xattr&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1&nbsp;1<br>
382 <font color="Red">/dev/sdb2</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/home&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;reiserfs&nbsp;&nbsp;&nbsp;defaults&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1&nbsp;2<br>
383 <font color="Red">/dev/sdb3</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;swap&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;swap&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;defaults&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0&nbsp;0</p>
384
385 <p>and we have to change ti to</p>
386
387 <p class="newcode"><font color="Green">/dev/hda1</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;reiserfs&nbsp;&nbsp;&nbsp;acl,user_xattr&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1&nbsp;1<br>
388 <font color="Green">/dev/hda2</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/home&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;reiserfs&nbsp;&nbsp;&nbsp;defaults&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1&nbsp;2<br>
389 <font color="Green">/dev/hda3</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;swap&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;swap&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;defaults&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0&nbsp;0</p>
390
391 <p>Finally, we unmount the partition, and we are ready to reboot</p>
392
393 <p class="newcode">umount /new-root<br>
394 reboot</p>

396 <H3><a name="reloc-img-boot-grub"></a>Reinstalling GRUB <span class="hideprint">[<a href="#reloc-img-top" title="go to top of the page">^</a>]</span></H3>
397
398 <p>When <b>Clonezilla-SysRescCD</b> menu appears, we select <i><b>Tools &gt; Super Grub Disk</b></i></p>
399
400 <p>Then we select <i><b>Super Grub Disk &gt; Super Grub Disk (WITH HELP) &gt; English Super Grub Disk &gt; Gnu/Linux &gt; Fix Boot of Gnu/Linux (GRUB)</b></i>. From this entry we will be able to reinstall GRUB to our hard disk.</p>
