I don't think that the growth/decrease is significant - not just 1% over a
period of two days. You'd need a lot more data to determine that there was
a problem from that alone.
However, checking df the amount of used space for Sunday is
2097152-1367816=729336. Yet du only shows 34060. This would indicate that
there is a considerable amount of data in / which du is unable to see.
The obvious cause for this would be a filesystem mounted over the top of a
directory which contains some data. df would show this as used space -
since it really is used - but du wouldn't be able to see the files and so
wouldn't tally them. Usual culprits are log directories, especially those
with NFS mounts.
If you had a log file which was in use, then a filesystem was mounted over
the top of it then it's possible that the original file - in / itself - is
still being used by whatever process was writing to it at the time. But as
I said: the data you've shown isn't sufficient to conclude that you've got
something eating your disk space.
