The cronjob task will look at all RBH databases and copy the stats into
our own database.

FileSystem Labels

Each filesystem now has the option of putting a user defined labeled
with different colours. This will help identify filesystems to users. An
example user case would be "public" filesystems vs "paid" filesystems or
"storage" filesystems vs "fast" filesystems. Again, all user defined and
not required.
