Might have messed this up. Clone of Snapshot creating dependency

[BrettSamuel]

Hi,

Assumption is the ,,,,, right? I think I've messed this up, trying to work out how to recover.

I wanted to split a filesystem into recent and old for backup purposes. So I cloned a snapshot called CameraArchive called it CamerArchiveLegacy and then deleted all but the new data with the intention of creating a separate dataset for vaulted images.

The assumption was that clones were not dependent on snapshots like it works in big storage arrays. But it seems not to be the case with ZFS, after the fact I can logically understand why. I don't understand why I am unable to delete the snapshot even after promoting the dataset.

Question:
I want to retain the data but have it as an independent dataset. Is there a smarter way than creating a new dataset and copying the data? I don't have enough free space for that.

Thank you
Brett

I think what you're looking to do is promote the clone to its own dataset.
