Well, I'm at work and will be until about 4am. Caroline is at home on her own, and I'm missing her loads.
During the file load we perform 3 partial backups of our Oracle database. For the last few months, the backups have been taking almost twice as long as they should have. However, on Tuesday, the backup drive had a sudden reform, and is now running at its proper speed again. So we should be able to knock about 3 hours off the time.
Thanks to poggs and clicker for keeping me company so far :-)
