SOLVED Odd snapshot

[blueether]

I changed from daily to hourly and got this odd snapshot with 0 Bytes used:

Code:

SATA_Z2/FreeNAS@auto-20190718.2016-12m / 7.41 MiB / 807.88 GiB / Thu Jul 18 8:16 2019
SATA_Z2/FreeNAS@auto-20190719.1941-8w  / 0 B      / 811.17 GiB / Fri Jul 19 7:41 2019

I deleted and re ran with the same results - should I worry about this?

A snapshot has no size if the data on disk is the same as in the snapshot, eg if you didn’t do any changes after taking the snapshot there wouldn’t be any size reported

of the ~50 auto snapshots these are the only 0B ones, and I know I put ~4 gig of photos on that dataset today

<edit>I have Replicated the snapshot to the other freenas box and the 4 gig of photos turned up so I guess nothing is amiss

I wonder if this is the snapshot on the source or on the replication target? I find all snapshots on my source show some size, but after replication, on the target the latest one always shows 0 B. Then, after the next replication, the previous snapshot on target shows some size. I feear I will never understand zfs, snapshots, and replication!
