I use it in a cron job and want to use the snapshots for the zxfer tool. I now use this line: /usr/local/sbin/zxfer -dFkPv -g 376 -R zroot backup01/pools I would like to have some snapshots on my system that are usable with this zxfer line. I once did create snapshots every ten minutes but the system got loaded with snapshots and transferring them (incremental) tot the backup system froze my kernel (vm.kmem_size too low) I have 2G ram and use a vm.kmem_size=512M Maybe this _is_ too small?
