Well, one could just compress it... If you'd otherwise put compression
in the ssh pipe (or elsewhere) then y
Wither it is efficient or not to send the compressed or uncompressed
data depends on a lot of factors.
If the data is already in the ARC for some other reason then it is
likely much more efficient to use that because sending the compressed
blocks involves doing IO to disk. Reading the version

In the "Thoughts on ZFS Pool Backup Strategies thread" it was stated that zfs
send, sends uncompress data and uses the ARC.
If "zfs send" sends uncompress data which has already been compress this is not
very efficient, and it would be *nice* to see it send the original compress
data. (or an op
