    <title>topic Lucene indexes: automatic corrections? in Alfresco Archive</title>

    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;SPAN&gt;Hi,&lt;/SPAN&gt;&lt;BR /&gt;&lt;BR /&gt;&lt;SPAN&gt;We are looking how we could build a backup system for our Alfresco installation and data. After reading the documents in the WIKI I do understand that it's advised to save the Lucene indexes but you could rebuild them from scratch if needed.&lt;/SPAN&gt;&lt;BR /&gt;&lt;BR /&gt;&lt;SPAN&gt;Now, when I add a document to the content repository it gets added to the Lucene indexes, if I remove a document it's removed (I suppose).&lt;/SPAN&gt;&lt;BR /&gt;&lt;BR /&gt;&lt;SPAN&gt;But what if a document is missing? Database inconsistence (pointer in database but the document is not on the file system or vice versa) may be possible and how does the Lucene indexes recover from these sorts of problems?&lt;/SPAN&gt;&lt;BR /&gt;&lt;BR /&gt;&lt;SPAN&gt;Will Lucene detect this and if so in what timeframe?&lt;/SPAN&gt;&lt;BR /&gt;&lt;BR /&gt;&lt;SPAN&gt;Thanks!&lt;/SPAN&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
