MORE INFORMATION
================

During an online backup, multiple log files may be generated even if circular
logging is enabled. This will occur during times of heavy use. This can result
in more than four log files being generated and used, even with circular logging
enabled. In Microsoft Exchange Server version 5.5, these log files are removed
after the backup is complete. In Microsoft Exchange versions 4.0 and 5.0, these
log files are not removed after the backup has completed.
