I'm working on some enhancements to zfs send/recv that will simplify
this even further, especially in cases where you have many filesystems,
snapshots, or changed properties. In particular, you'll be able to
simply do:
# zfs snapshot -r [EMAIL PROTECTED]
# zfs send -r -b [EMAIL PROTECTED] | ssh newbox zfs recv -p -d newpool
The "send -b" flag means to send from the beginning. This will send a
full stream of the oldest snapshot, and incrementals up to the named
snapshot (eg, from @a to @b, from @b to @c, ... @j to @today). This way
your new pool will have all of the snapshots from your old pool.
The "send -r" flag means to do this for all the filesystem's descendants
as well (in this case, space/jbeck and space/local).
The "recv -p" flag means to preserve locally set properties (in this
case, the mountpoint and sharenfs settings).
For more information, see RFEs 6421959 and 6421958, and watch for a
forthcoming formal interface proposal.
