The ZFS automatic snapshot tools have the ability to execute any command after a snapshot has taken place, such as ZFS send. However, I ran into some issues, as it wasn't strictly designed for that and didn't handle errors very well. I have since modified some scripts out there, and rolled them into my own, you can see it here at pastebin.com: http://pastebin.com/m3871e478 Inspiration: http://blogs.sun.com/constantin/entry/zfs_replicator_script_new_edition http://blogs.sun.com/timf/en_IE/entry/zfs_automatic_snapshots_in_nv Those are some good resources, from that, you can make something work that is tailored to your environment. -- Brent Jones br...@servuhome.net _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
