If you want to use Fletcher, you need to use verify, as the likelihood of
collisions is increased since Fletcher is not *random*. You don't really
need to verify when using SHA256, and by default, SHA256 is used with
dedup, not Fletcher. . More information about the checksumming and
trade-offs can
Jan,
I'm not sure that turning dedup or compression on is useful in your
particular situation.
Since the images are already compressed, re-compressing them only adds
cpu overhead without much benefit. Also, Since images will have little
opportunity for dedup (unless you tend to have multiple
Thank you for the replies.

Someone can correct me if I'm not 100% accurate, but:
Those features are thoroughly tested and not experimental. That said:
nothing is guaranteed to keep your data safe, and if you're truly worried
about it, don't use dedupe. In fact set ZFS to write multiple copies of
everything. Create a ZFS poo
Hi,
I'm building a home NAS so I don't care too much about performance,
but *do* care if I lose all my photos. I'm aware that ZFS had a very
extensive test suite that ensured that data is kept safe.
Are the newer capabilities (specifically checksum=sha256,
compression=on, dedup=verify) thoroughly
