SOLVED Sync with Backblaze not deleting files from destination

[Penobscot]

I have a push sync task that transfers files as expected but does not delete them, which I am now doing via the Backblaze UI. I've seen similar threads here but they are old. Is there something else I need to do, or does this feature not work? Thanks

Unfortunately, I used examples from the internet to set up the task rather than RTFM. Per https://www.truenas.com/docs/core/coretutorials/tasks/creatingcloudsynctasks/

Syncing to a Backblaze B2 bucket does not delete files from the bucket, even when you delete those files locally. Instead, Backblaze tags files with a version number or moves them to a hidden state. To automatically delete old or unwanted files from the bucket, adjust the Backblaze B2 Lifecycle Rules.

I set up a rule, and assuming it works I'll call it a day.
