A important thing to consider is file system fragmentation and
number and size of files, which may impactseverely on performance.
In order to check this, try to create a single big file (2 GB, for example)
and
create a test policy to backup only that file. Under normal conditions,
on a idle system/network, you should be able to get over 50 MB/s.
