I've set the loglevel to 2 and made a manual incremental run with #342, 
this is a small posrtion of the log:

Almost all files are marked "pool" and all directories are marked "create". 
There are files marked "skip" and some "same", but only a few.
The duration of this run was 175 minutes.

Before this I made another manual incremental run (with log level 1) #341. This 
run has almost all files marked "skip"
and only a few files marked "pool". All directories are also marked "create". 
This run lasted for 7 minutes.

Also noticeable is the line: "incr backup started back to 2009-06-13 10:59:37 
(backup #341) for directory data" above.
Does this mean this run, 342, is "compared" to 341? And if so, would that 
explain this behaviour? It seems that
files in run 341 which are marked "create" or "pool" are skipped in 342. 
Skipped files in 341 is marked "pool" in 342.

Also a bit peculiar is the fact that all directories are marked "create" but 
this is perhaps normal?
