Jan,

This doesn't sound right.
The DP for xxx clients should be able to restore the data
without having to do anything special.

Files which are inaccessible to the storage agent
are supposed to be restored, although there will be a performance hit.
These files are supposed to be proxy restored from the server to
the storage agent and from there back to the client (the data is moved
twice).

If you are not finding that to be the case,
please call IBM support.

Thanks,

Del
