Confusion regarding Replication Tasks

[steve.long]

I'm attempting to set up my replication tasks on FreeNAS1. The Snapshots run between 0630 and 1830 then stop. Then my replication task starts at 2030 and I end it at 0530.

So on FreeNAS2 I get ALL these 15 minute interval snapshots. But since FreeNAS2 is my offsite, I really have no use for that frequency. I'd prefer to have a single snapshot from the end of the day.

Do replication tasks replicate ALL snapshots for a single dataset?

Do replication tasks replicate ALL snapshots for a single dataset?

This is how the default FreeNAS replication task works.

Now, each snapshot only captures the changed blocks. Unless you are writing and deleting a ton of data with each snapshot, the margin data transferred with each additional snapshot is trivial. My guess is (again, unless you are writing and deleting a ton of data in that window), the total amount of data transferred for each of the 15 min snapshots is not much more, if any more, than what you'd get with only a daily snapshot.
