Managing multipe boot environments w/ snapshots on Solaris 10 and 11

I want to make a snapshot of the boot environment once a week. I want to keep three weeks worth. It looks like I can do this with the auto-snapshot service with Solaris 11, but I can't find it on 10. Does anyone have something similar already set up? I would like to do it with a cron job and ksh script if the service won't run on Solaris 10.

Thanks in advance,
David

In Solaris 10, there is a command called "fssnap", please see this link for example:

Will that work for ZFS though? It says that's for UFS.

Sorry, I probably wasn't clear. I can do the snapshots, I was wondering if anyone had devised a script or process for managing the snapshots. Something that would make a snapshot of the rpool once a week and keep a running 3 copies. So it would delete the oldest one, and make a new one, not necessarily in that order. I know Solaris 11 has the auto-snapshot package, but I don't think I can get it on 10 so it looks like I'll be scripting it unless someone has already invented the wheel.

Ganjos, I'm going to end up using time-slider and auto-snapshot. Your link gave me some good info though. Thanks.
