We were snapping every hour with send/receive times on the order of 25 minutes. I do not believe there will be time to experiment with other combinations. > Is it catastrophic if a second zfs send launches, while an older one > is still being run > I use a semaphore property to help avoid this, by design. That said, I have not tried to see if there is a lurking bug with ZFS receive that would need to be fixed if it cannot handle concurrent receives. My send/receive script will incrementally copy from the latest, common snapshot to the latest snapshot. For rsync, it will sync from the epoch to the latest snapshot. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
