That's correct, you can't. Snapshots do not work at the file level.

looking through some more code.. i was a bit premature in my last post - been a
long day.
extracting the guids and query the metadata seems to be logical - i think
runnign a zfs send just to parse the data stream is a lot of overhead, when you
really only need to traverse metadata directly.

This may be redundant in light of my earlier post, but yes it does.
Directory mtimes are updated when a file is added or removed, and
find -newer will detect that.

Is there a possibility to get a list of changed files between two
snapshots? Currently I do this manually, using basic file system
functions offered by OS. I scan every byte in every file manually and
it is of course awfully slow.
If I have understood correctly, ZFS could use its
Okay, so first of all, it's true that send is always fast and 100%
reliable because it uses blocks to see differences. Good, and thanks
for this information. If everything else fails, I can parse the
information I want from send stream :)
