<title>Ako sve ode po zlu</title>

<p><app>Déjà Dup</app> may fail.  Maybe it crashes or gives you an error when you try to restore.  When you really need your data back, the last thing you want do deal with is a bug.  Consider filing a <link href="https://launchpad.net/deja-dup/+filebug">bug report</link> but in the meantime, here are some approaches to workaround a misbehaving <app>Déjà Dup</app> and get your data back.</p>

<note><p>Ovo će nastaviti sa malo tehničkih terminologija. Ako ništa od ovoga ne razumijete, nemojte se bjati <link xref="support">tražiti pomoć</link>.</p></note>

<steps>
  <item><p>Ovorite <app>Terminal</app> prozor pritiskom <keyseq><key>Ctrl</key><key>Alt</key><key>T</key></keyseq>.</p></item>
  <item><p>Create the directory in which you will place your restored files.  This guide will use <file its:translate="no">/tmp/restore</file>:</p>
<screen its:translate="no">mkdir -p /tmp/restore</screen></item>
</steps>

<title>Povrat sa Duplikacijom</title>

<p>On the assumption that <app>Déjà Dup</app> is just not working for you right now, you’re going to use the command line tool <app>duplicity</app> that is used by <app>Déjà Dup</app> behind the scenes to back up and restore your files.</p>

<note style="advanced"><p>If you want more information about <app>duplicity</app> than presented here, run <cmd>man duplicity</cmd>.</p></note>

<p>The first thing we’ll try is a simple restore of all your data.  Assuming your files are on an external drive mounted as <file its:translate="no">/media/backup</file> and you chose to encrypt the backup, try this:</p>
<screen its:translate="no">duplicity --gio file:///media/backup /tmp/restore</screen>

<p>If you didn’t encrypt the backup, add <cmd its:translate="no">--no-encryption</cmd> to the command.</p>

<section id="locations">
<title>Druge lokacije rezervnih kopija</title>
<p>If you backed up to a remote or cloud server, the syntax you use with <app>duplicity</app> will be different than the external drive example above.  See below for how to connect to your chosen backup location.</p>
<note><p>Remember to add <cmd its:translate="no">--no-encryption</cmd> to any example commands if your backup is not encrypted.</p></note>
<p>If <app>duplicity</app> appears to be having trouble connecting to your server, try downloading all the <app>duplicity</app> files yourself to a local folder and following the simpler example above.</p>

<p>If even <app>duplicity</app> isn’t working for you, there may be little hope.  The backup file format is complicated and not easily manipulated.  But if you’re desperate, it’s worth a try.</p>

<p>If you used a remote or cloud server to store your backup, first download all the <app>duplicity</app> files and place them in a folder on your computer.  Then enter that folder in your terminal.</p>

<p><app>Duplicity</app> stores your data in small chunks called volumes.  Some volumes belong to the periodic ‘full’ or fresh backups and others to the ‘inc’ or incremental backups.  Starting with a full backup set of volumes at volume 1, you’ll need to restore files volume by volume.</p>

<p>If you encrypted your backup, first you must decrypt the volume with <cmd its:translate="no">gpg</cmd>.  Say you have <file its:translate="no">duplicity-full.20110127T131352Z.vol1.difftar.gpg</file>:</p>
<screen its:translate="no">gpg --output duplicity-full.20110127T131352Z.vol1.difftar --decrypt duplicity-full.20110127T131352Z.vol1.difftar.gpg</screen>

<p>Ili uraditi sve odjednim (provjerite da imate dovoljno prostora!):</p>
<screen its:translate="no">gpg --multifile --decrypt duplicity-full.20110127T131352Z.*.difftar.gpg</screen>

<p>Now you have either a <file its:translate="no">.difftar</file> or a <file its:translate="no">.difftar.gz</file> volume (depending on whether you had to decrypt it or not).  Use <cmd its:translate="no">tar</cmd> on whichever one you have to extract the individual patch files:</p>
<screen its:translate="no">tar xf duplicity-full.20110127T131352Z.vol1.difftar</screen>

<p>Ili ponovo, uraditi sve odjednom:</p>
<screen its:translate="no">for t in duplicity-full.20110127T131352Z.*.difftar; do tar xf $t; done</screen>

<p>Now the patch files will be in <file its:translate="no">multivolume_snapshot</file> and <file its:translate="no">snapshot</file> folders.  Each file that spanned multiple volumes will be in <file its:translate="no">multivolume_snapshot</file>. Let’s say you backed up <file its:translate="no">/home/jane/essay.txt</file>:</p>
<screen its:translate="no">cd multivolume_snapshot/home/jane/essay.txt
cat * &gt; essay.txt</screen>

<p>To recover data from incremental backups, use <cmd its:translate="no">rdiff</cmd> to stitch the files together. See <cmd its:translate="no">man rdiff</cmd> for usage.</p>
