I was taught that you need at least twice as much available disk space as
your largest client's index. My Solaris 9 NetWorker 7.1.3 server is
running at 63% right now for its index volume, which also contains the
media database, the nsr logs, and other NSR stuff, such as the res
directory. This is all on a StoreEdge A1000 that's RAIDed.

We're probably going to move our NSR index files to a larger volume on a
SAN in a few months because I do expect to use a lot more disk space as we
add additional clients to back up. So far though, I haven't run into any
problems as a result of us running with our /nsr volume at 63% of
capacity. We were at 61% for several months, but I recently added some
large clients, so it pushed it up some.
