Hello, my comment is for your #2..

On the DD box the "cleaning" process is by default set to use 50% of the cpu 
and it throttles back if the DD box has other actions to perform.  The cleaning 
job properties are configurable so you can reset any of the times and values.  
Best practice is to set the cleaning time when the DD box is not busy, but know 
beforehand if you already have it set to an offpeak time it may just take 5 
hours for it to clean.  I guess you could alter the throttling up a bit, but 
then if there are other things going on those may slow down..

Subject: Re: nsrim and DataDomain behaviour

Hello all,

sorry I didn´t say thank you for your replies earlier, but I had a few days off 
and a few problems with my account.

In the meantime I hope we could locate two points:
1) We have two clients with lots and lots of small files, index-check for both 
of them lasts from one to two hours. This problem should be resolved now, but 
we have to wait a few weeks until the index will be cleaned and the check will 
be faster
2) After nsrim and nsrck is finished, the place reclaiming process at the 
DataDomain starts. We have two DD880 in use, which are replicating. On the 
first one the reclaiming process is finished after 60 to 90 minutes, which is a 
time I can accept. On the other DD the reclaiming process lasts up to four or 
sometimes 5 hours, what is really a problem. Both DD are equally configured and 
share the same space. DD2 holds more data, because it was configured first, but 
that shouldn´t cause so much difference. For us ist seems to be more a 
DataDomain than a Networker problem, I think next thing to do is to open a call 
there.

Regards,
Christian
