This is a good idea, one that we've had in the back of our minds for a long time, but apparently never put into a bug report. I've filed RFE 6453726 "want snapshot every txg". As a workaround, you could write a script to simply take a snapshot every N seconds. It could clean out snapshots that are not different from their neighbors (although this may be difficult to determine with 100% reliability), and old snapshots that are using too much space. --matt _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
