Consider using different policies for different data. For traditional file
systems, you
had relatively few policy options: readonly, nosuid, quota, etc. With ZFS,
dedup and
compression are also policy options. In your case, dedup for your media is not
likely
to be a good policy, but dedup for your backups could be a win (unless you're
using
something that already doesn't backup duplicate data -- eg most backup
utilities).
A way to approach this is to think of your directory structure and create file
systems
to match the policies. For example:
/home/richard = compressed (default top-level, since properties are
inherited)
/home/richard/media = compressed
/home/richard/backup = compressed + dedup
-- richard
