<span id="deduplication"></span><h1>Hvordan fungerer deduplikeringsprocessen?<a class="headerlink" href="#how-does-the-deduplication-work" title="Link to this heading">¶</a></h1>
<p>Processen med at fjerne redundante filer og erstatte dem med NTFS-hardlinks ved hjælp af TreeSize kaldes <strong>deduplikation</strong>. Dette vil reducere den diskplads, der er blokeret af dine duplikatfiler.</p>
<p>I stedet for at hver af filerne optager individuel plads på din harddisk, fjerner TreeSize alle duplikatfiler og beholder kun én af dem.</p>
<p>De filer, der blev fjernet, vil blive erstattet af hardlinks, som derefter peger på de resterende data (Se: <a class="reference internal" href="notesonntfs.html#notesonntfs"><span class="std std-ref">Noter om NTFS</span></a>).</p>
<p>Dataene deles nu af alle hardlinks for denne fil, som vist i billedet nedenfor.</p>
<a class="reference internal image-reference" href="_images/Deduplication.png"><img alt="_images/Deduplication.png" class="align-center" src="_images/Deduplication.png" style="width: 100%;" />
</a>
<p>Disse hardlinks kan bruges som enhver normal fil. Du vil ikke bemærke nogen forskel, bortset fra at dataene nu deles mellem de andre links. Faktisk er de ikke forskellige fra enhver normal fil, bortset fra at de ikke optager deres egen plads.</p>
<section id="which-of-the-duplicate-files-will-be-replaced">
<h2>Hvilke af duplikatfilerne vil blive erstattet?<a class="headerlink" href="#which-of-the-duplicate-files-will-be-replaced" title="Link to this heading">¶</a></h2>
<p>Hvis du markerer alle filer i en duplikatgruppe, vil TreeSize vælge filen med den nyeste »Sidst ændret« dato og bruge den som »master« for denne gruppe. Alle andre filer vil blive fjernet og erstattet af hardlinks, der peger mod masterfilen.</p>
<p>Hvis du ønsker at vælge en masterfil manuelt, kan du lade en af filerne i en duplikatgruppe være umarkeret. Denne fil vil så ikke blive erstattet, men bruges som master i stedet.</p>
<div class="admonition note">
<p class="admonition-title">Bemærk</p>
<p>Desværre viser Windows Stifinder ikke størrelsesforskellen for en dedupliceret fil eller den mappe, den er placeret i. <a class="reference external" href="https://knowledgebase.jam-software.com/7259">Læs vores vidensbase</a> for mere information.</p>

<p class="admonition-title">Bemærk</p>
<p>Alle hardlinks, der peger på den samme fil, deler den samme »Sikkerhedsbeskrivelse« (adgangstilladelser). Deduplikation vil anvende et ensartet sæt af tilladelser til den ene fysiske resterende fil.</p>
