I don't think you have any choice. There is such a thing as "zfs send" and there is no such thing as "zpool send." You can use -R for replication recursive, which is kind of like doing the zpool directly... But not exactly. The only gotcha is to ensure your applications (whatever they are) are resilient to power failure. Because the zfs snapshot will literally produce a block-level snapshot of the way the disks are right now, at this instant. If you ever need to restore, then it will be as-if you sustained a power loss and came back online. The most notable such situation would probably be databases, if you have any. Ensure to use a database backup tool to export the database to a backup file, and then send the filesystem. Or else momentarily stop the database services while you take the snapshot. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
