I looked into backing up ZFS and quite honostly I can't say I am convinced about its usefullness here when compared to the traditional ufsdump/restore. While snapshots are nice they can never substitute offline backups. And although you can keep quite some snapshots lying about it will consume diskspace, one of the reasons why people also keep offline backups.
However, while you can make one using 'zfs send' it somewhat worries me that the only way to perform a restore is by restoring the entire filesystem (/snapshot). I somewhat shudder at the thought of having to restore /export/home this way to retrieve but a single file/directory. Am I overlooking something here or are people indeed resorting to tools like tar and the likes again to overcome all this? In my opinion ufsdump / ufsrestore was a major advantage over tar and I really would consider it a major drawback if that would be the only way to backup data in such a way where it can be more easily restored.
