Ok, this seems like an NMV bug. If I make the auto-snap in NMC it works (snapshotting every minute). The problem is it's no longer "Keep X snapshots", it's KeepDays (days of snapshots). The NMV seems to still be trying to write keep-up-to into the snapshot service and is not reading the proper variable (keepdays) now.

Retention policy revised

Auto-snap: keep_days parameter defines number of days to keep snapshots on appliance.

Auto-tier: keep_days parameter defines number of days to keep snapshots on local appliance. Local appliance is the source appliance if service is local-to-remote. If service is remote-to-local, local appliance is destination.

Auto-sync: keep_days parameter defines number of days to keep snapshots on both ZFS systems.

If service is already created by previous versions of appliance, 'keep_days' property will be calculated during first run of upgraded service. New 'keep_days' value is based on old 'keep' value. For second, minute, hourly services new 'keep_days' value will be equal to 1 day. For daily, monthly services new 'keep_days' property will be translated by multiplication of 'keep' and 7 and 30 accordingly. Please check that new 'keep_days' value fits your needs by issuing command: nmc$ setup auto- : property keep_days

The problem is, if you look at my snap-logs that even with a "keep_days" value of 1, it's deleting my minute snapshots every 1 minute. It should, by all intensive purposes allow me to keep 1440 snapshots if I take 1 per minute for 1 full day.

Also, the GUI verbage needs to change from "keep up to" to "keep for days" as to not confuse the end user.
