Saves a copy of the complete log file in a backup directory, which has to be specified in the Options / Automatic backup dialog. If this directory is embedded in a floppy disk, it has to be present in the drive A: while executing this command. The file will have an additional .bak extension (test.wtb.bak for example). To use this backup file, just rename the file without the .bak extension.
Warning : A 1.44 MB floppy disk will accept no more than approximatly 7000 QSO !
