[rdiff-backup-users] Speed issue in first run

Hi list, 

I joined the list just now.

First some background info:

I have almost a terabyte to back up, and so far I have used a single
one-line rdiff-backup script to do it all. The script runs every night, and
36 increments are stored.

A couple of weeks ago something happened, and rdiff-backup started to crash
each time I tried a backup.

Now I did what I probably should have done a long time ago: divided the huge
target directory to several directories, with a dedicated rdiff-backup
script for each. 

Now to the question:

When I run rdiff-backup for the first time for each new directory (with
--force), the run takes very long. It takes about as long as copying it all
from source, even though almost all of the content is already in place at
the target directory.

How could I speed this up? Does it matter if there is a manually created,
empty rdiff-backup-data directory ready in place (in one test I got the
impression that this might help).

I wouldn't want to wait for the next couple of weeks for my script to
finish. :-) 

Any suggestions?

- Jussi
