Replicate to an encrypted data set

TrueNAS General

I must be doing something wrong, but don’t know what and what the consequences may be…

I have a main backup machine (let’s call it “A”), the dataset I backup is not encrypted. I use a replication task to backup the backup to another machine (“B”) where the parent dataset of the destination dataset is encrypted.

The replication seems to have worked but I do get a warning in the webui:

Warning

The following datasets are not encrypted but are within an encrypted dataset:

'bpool0/enc_vault/backup_from_main' which is not supported behaviour and may lead to various issues.

I thought it’s fine to encrypt the parent data set and every child will be encrypted too. What did I do wrong and what would be the recommended setup?

TIA, Florian

How did you configure the Replication Task?

If you enabled “Full Filesystem Replication” or “Include Dataset Properties”, then an unencrypted dataset will be sent as it is on the source: unencrypted. It will not inherit the properties of the parent on the destination.

Hi,

thanks for your quick reply.

I think that’s what I did wrong. I now created a new (encrypted) dataset on the destination machine and set up the replication as followed:

Better?
Let’s see what happens.

OK, that made the trick. It’s required to check Encryption in the replication process…
