What's the best way to backup a zfs filesystem to tape, where the size

ufsdump handles this quite nicely. Is there a similar backup program
for zfs? Or a general tape management program that can take data from
Previously it was suggested on this list to use a special version of
tar called 'star' (ftp://ftp.berlios.de/pub/star).
Suggested by the rather biased (and extremely opinionated) author of
'star'. Who, by the way, never out-and-out admitted that star does _not_
support ZFS ACLs (which it doesn't).
Sadly I don't now of any non-commercial backup solution for ZFS that
supports ACLs.
That is simply not true. Legato (EMC) Networker 7.4 does a perfect job
of capturing the ZFS ACL's Just to make sure, I just performed a test
recover of a directory where we use a complicated set of NFS4 style
ACL's, and they were preserved exactly.
Even rsync doesn't support them, due to Sun's choice to
use their own unique ACL API.
I commend Sun's choice of NFS v4 ACLs. This is the only way to ensure
CIFS compatibility, and it is the way the industry will be moving.
