Aye, that's what I was hoping for. Since ZFS seems to support nesting filesystems, I was hoping that each filesystem would contain the others, so a snapshot of the root filesystem would also be a snapshot of the others.
I'm still not sure if that's the case or not, it could be that -r just means you have individual snapshots as well (handy for restores). Going to do some testing now I have zfs running, if it comes to it I'm hoping I can use -r and script a backup of all the filesystems. Scripting zfs send from that shouldn't be too hard, I'm just hoping it's not going to be too complex to script the zfs receive side of it. I guess the ideal for me would be for filesystems to include child filesystems in their snaphots and for zfs snapshot -r to recursively snapshot each filesystem, starting from the topmost branches of the tree and working backwards. That would mean you could backup the entire system by just copying one snapshot, but you would have contained within that individual snapshots for each child filesystem. Apologies for my inconsistent (or just plain wrong) use of terminology. I've only started using ZFS this week, and hadn't even touched a Unix system before that!
