Rather having to write something like: #!/bin/bash TIME=`date ''+%Y-%m-%d-%H:%M:%S''` zfs snapshot -r ztank@$TIME for i in `zfs list -H | grep $TIME | cut -f1` ; do zfs send $i | ssh ihstore zfs receive -d tank/sstore-ztank ; done That is just a first run, I''ll need to add a a touch /ztank/.LASTSEND+$TIME file and do some parsing and stuff to make it all incremental. It would be much nicer to do something like: zpool snapshot ztank@$TIME zpool send -i ztank@$LAST ztank@$TIME | ssh BACKUPHOST zpool receive remote-tank/ztank-backup then another pool on the same machine to same backup pool on the remote machine. zpool snapshot mtank@$TIME zpool send -i mtank@$LAST mtank@$TIME | ssh BACKUPHOST zpool receive remote-tank/mtank-backup Possible or is this going to break the zfs model?

You want:
6421958 want recursive zfs send (''zfs send -r'')
Which is actively being worked on.

Maybe just assume that anyone who wants to use send -r must implicit have run snapshot -r. So just ignore the ''snapshot -r'' and have a complete snapsend -r.

While I would really like to see a zpool dump and zpool restore so that I could throw a whole pool to tape it is not hard to script the recursive zfs send / zfs receive. I had to when I had to recover my laptop. http://blogs.sun.com/chrisg/entry/recovering_my_laptop_using_zfs --chris This message posted from opensolaris.org
