Package: rdiff-backup

Thanks for maintaining Debian's rdiff-backup
package.
It's good at backing up linux data.
However, I noticed that it fails when run under
linux to back up one MS Windows file system to
another.
The source and destination directories and devices
are:

Fatal Error: Bad rdiff-backup-data dir on destination side
The rdiff-backup data directory
/mnt/dos_backup/rdiff-backup-data
exists, but we cannot find a valid current_mirror marker. You can
avoid this message by removing the rdiff-backup-data directory;
however any data in it will be lost.
Probably this error was caused because the first rdiff-backup session
into a new directory failed. If this is the case it is safe to delete
the rdiff-backup-data directory because there is no important
information in it.
The rdiff-backup-data appears to be named
/mnt/dos_backup/rdiff-ba and created every time
rdiff-backup is run.
Thanks,
Kingsley
