Backup Central

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

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..
