JFTR, I also hit this problem. It happened during the switch of daylight savings, causing two backups being created the same day, with a different timezone offset (+1 and +2).
After removing all backup files from that day, everything worked again. Cheers, Carsten -- Fraunhofer Institute Computer Architecture and Software Technology, FIRST Kekuléstraße 7, 12489 Berlin Tel.: +49 (0)30 6392-1900, Fax: +49 (0)30 6392-1805
