I went ahead and hacked this script together, so let me elaborate. First,
though, a teaser:

Is there a way to get the total amount of data referenced by a snapshot
that isn't referenced by a specified snapshot/filesystem? I think this is
what is really desired in order to locate snapshots with offending space
usage. The written and written@ attributes seem to only do the reverse. I

For illumos-based distributions, there is a "written" and "written@" property
that shows the
amount of data writtent to each snapshot. This helps to clear the confusion
over the way
the "used" property is accounted.

As I understand it, the used space of a snapshot does not include anything
that is in more than one snapshot. There is a bit of a hack, using the
verbose and dry run options of zfs send, that will tell you how much data
must be transferred to replicate each snapshot incrementally, which should

All,
I apologize in advance for what appears to be a question asked quite often, but
I am not sure I have ever seen an answer that explains it. This may also be a
bit long-winded so I apologize for that as well.
I would like to know how much unique space each individual snapshot is using.
