title: Firebird error during backup
body: <p>i want to backup firebird database. Below is command that i use to execute the backup.</p>
  
  <pre><code>gbak -b -v -user SYSDBA -pass ***** -service localhost:service_mgr -verify -y E:/logs/backup_20111104.log D:\data\campaign.FDB E:/backup/campaign_20111104.fbk -FIX_FSS_METADATA WIN1252 -FIX_FSS_DATA WIN1252
  </code></pre>
  
  <p>However, after 2 hours running, it ends with general error(only in last line). Below is the error.</p>
  
  <pre><code>gbak:22068 records written
  gbak:    writing data for table AA_1307265720107_842
  gbak:19872 records written
  gbak:    writing data for table AA_1301338383915_1025
  gbak:4 records written
  gbak:Exiting before completion due to errors
  </code></pre>
  
  <p>There is 700+ tables in this database. And the database size is 129GB. </p>
  
  <p>I need to get complete stacktrace(if any). Or any idea where to check so i can know the actual error?</p>
