I'm curious as to what advantage deduplication gives you on a home
server? On a large file system with thousands of users, I can see how
it could be a benefit there. But on my own computer, the large storage
is taken up by photos, music, and video and I highly doubt there are
many duplicate blocks there.
I suppose if you're PXE-booting multiple computers with an NFS root file
system, then deduplication could be of some benefit. Or maybe virtual
machines. Some years ago, Red Hat was working on a system to kind of of
do this, which they called "Stateless Linux". I'm not sure if it's
still an active thing or not. For me disk was too cheap to worry about
this sort of thing.
