Re: Cloud Sync, TrueNAS (scale/bluefin) seems not to allow you to specify an existing Bucket (all are greyed out). But it DID let me add a new bucket. And it shows success syncing with the new Bucket.
Apparently, when you set up the S3 credentials in Storj, you will specify a passphrase. That is the passphrase that the new bucket will be encrypted with. But buckets not created with those credentials are not accessible, even if you use the same encryption passphrase.
Or maybe I'm just missing something.
Regardless, this is a very different and interesting paradigm.
