[rdiff-backup-users] Strange Error -> No space left on device

Hi everybody,

can anyone of you help me with my problem? I got this error message 
tonight from our system:

IOError: [Errno 28] No space left on device

rdiff: ERROR: IO error
backup of /etc

At first it seemed clear that there is no space on device. The 
/temp-file became too big. But how is the system able to make a backup 
of /etc (last line) but not of /pulic (first line). I thought that there 
is too less space...

The backup system worked for some weeks perfectly. No message that the 
space is too small. Why is the temp-file becoming so big? What are the 
reasons therefore?

Thanks in advance for your help,

Robert
