cpio is not a good idea, it is amongst other problems limited to 8 GB per file
with the POSIX format, the SVr4 cpio format is limited to 4 GB per file.

If you don't need ZFS ACLs, I recommend star. It supports true incremental
backups using a similar strategy than ufsdump for the incrementals.
Star does not yet support ZFS ACLs but it does support UFS ACLs.
Another feature of star star is of interest for backups is multi volume support
in a way that allows you to start restoring with any volume (in case you don't
like to do an incremental restore but are just looking for single files).
