@△ TRiANG-ouL's avatar ▽ @ @menherahair :redeyeorb: bro, check zfs-auto-snapshot(1)
it will install the scripts on your /etc/periodic for you. here's the daily script:
#!/bin/sh
# Only call zfs-auto-snapshot if it's available
which zfs-auto-snapshot > /dev/null || exit 0
exec zfs-auto-snapshot --quiet --syslog --label=daily --keep=31 //
its been runnin just fine. why would this one work and not the other?
