The snapshots taken by the package zfstools depends on this property: $ zfs get all zroot/usr/home|grep auto-snapshot zroot/usr/home com.sun:auto-snapshot true local It turns out that when I sent my snapshots to my backup machine, I never turned off this property, the backup machine also had zfstools installed, and so was taking snapshots of my backupsnaphots. Hence the holes. I've since cleaned this up, and will let backups run for a few days and see if this fixes the problem. Alex
