Just wanted to voice another request for this feature. I was forced on a previous Solaris10/ZFS system to rsync whole filesystems, and snapshot the backup copy to prevent the snapshots from negatively impacting users. This obviously has the effect of reducing available space on the system by over half. It also robs you of lots of I/O bandwidth while all that data is rsyncing, and means that users can't see their snapshots, only a sysadmin with access to the backup copy can.
We've got a new system that isn't doing the rsync, and users very quickly discovered over-quota problems when their directories appeared empty, and deleting files didn't help. They required sysadmin intervention to increase their filesystem quotas to accomodate the snapshots and their real data. Trying to anticipate the space required for the snapshots and giving them that as a quota is more or less hopeless, plus it gives them that much more rope with which to hang themselves with massive snapshots. I hate to start rsyncing again, but may be forced to; policing the snapshot space consumption is getting painful, but the online snapshot feature is too valuable to discard altogether. or if there are other creative solutions, I'm all ears...
