OK, so sounds like there is no problem here, right? You were taking snapshots every 4 hours, which took up no more space than was needed, but more than you would like (and more than daily snapshots). Using daily snapshots the space usage is in line with daily snapshots on NetApp. > For various reasons, I can't post the zfs list type results as yet. > I'll need to get the ok for that first..

It sounds like there is no problem here so no need to post the output. --matt _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
