Yes, NetWorker will manage the expiry and deletion of this data together with Data Domain. Once the retention period is passed, it'll be done automatically. As regards, how much space will be cleared up, it's a little more complicated:
In my case it didn't work as you said. I have to run nsrstage -C -V volume_name or nsrim –X to recover the space. And it works only when no backups are in progress. And that's a little bit problematic because backups are done almost all the time on this volume. Any suggestions? I use NW 8.0
mariusz - I use NW8 and it works just fine (at least with DD Boost devices - which kind of devices do you use?) I would also suggest to open separate thread as issue of OP has been resolved.

Hi,
Yes, NetWorker will manage the expiry and deletion of this data together with Data Domain. Once the retention period is passed, it'll be done automatically. As regards, how much space will be cleared up, it's a little more complicated:
From the NetWorker Data Domain Devices Integration Guide, page 25
"Reclaiming expired storage space
When a backup on a Data Domain system reaches its retention expiry date, all its
references to the data become invalid. However, unlike traditional storage systems,
space is not immediately freed up on the device because other backups or clients may
have deduplication references to the same data.
For example, the deletion of 1 GB of data, even of unique data from a NetWorker
perspective, does not result in 1 GB of space made immediately available on the Data
Domain system.
The DD OS filesys show space or df command shows the data that is eligible to be
deleted from the Data Domain system under the Cleanable GiB column.
A review of deduplication references and storage space occurs during a periodic
cleanup operation, which is scheduled by default to run once per week.
Note: If a NetWorker Data Domain device becomes full during a backup, the backup fails
immediately. It does not pause or wait for space to become available.
The DD OS filesys clean command describes all the available options for managing
how the storage space for redundant or expired data (such as expired NetWorker
save sets) can be reclaimed and recycled.

So You think that Networker 8 will delete every expired save set automaticly without my intervention on DD?
