[rdiff-backup-users] rdiff-backup for changes only

[Herman Lim]

Hi All,

Does anyone know if there's a way to use rdiff-backup to make  
incremental 'backups' of changes only? ie. without mirroring the  
original directory (then the changes subsequently).

Have a massive source directory and would only like to keep track of  
the changes only.

Thanks in advance,

Herman
