Backup Central

Hi everybody,

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

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

rdiff-backup requires temporary space on the system being backed up, and I
suspect it is that that is running out of space. Once the backup of /public
has failed, the temporary space is cleared and the backup of /etc succeeds.
I suspect /etc is smaller than /public.

What does the output of 'df' show on the system being backed up?

The system partition (including /etc) is filled with 100%. The problem is that this partition has got a size of just 1 GB.
It wasn't set up by me, so I don't know the reason why it is so small...

Should then /tmp be filled with less than 100% if it is cleared during the backup?

Thanks

The system (ie, root) partition always includes /etc.

the backup?

Well it's unlikely to be filled more than 100% (although possible), so I
suppose the answer is 'yes'. /tmp isn't cleared during backups (not by
rdiff-backup anyway). I suggest you concentrate on fixing the fact that
your root partition is full before you worry about why rdiff-backup doesn't
work.
