Depending on the data content that you're dealing you can compress the
snapshots inline with the send/receive operations by piping the data
through gzip. Given that we've been talking about 500Mb text files,
this seems to be a very likely solution. There was some mention in the

It is more cost, but a WAN Accelerator (Cisco WAAS, Riverbed, etc.) would be a
big help.

So the conclusion I draw from this is that the --incremental-- snapshot simply

I took binary dumps of the snapshots taken in between the edits and this showed
that there was actually very little change in the block structure, however the
incremental snapshots were very large. So the conclusion I draw from this is
that the snapshot simply contains every written block since

I am looking to use Opensolaris/ZFS to create an iscsi SAN to provide storage
for a collection of virtual systems and replicate to an offiste device.
While testing the environment I was surprised to see the size of the
incremental snapshots, which I need to send/receive over a WAN connection,
