I've just been looking into this and have seen Synology Note Station, which is apparently quite a competent Evernote clone has an 'archive' feature. I haven't tested this yet as my own Synology NAS is currently in storage whilst I move house but as soon as it's back up and running I'm going to be looking into this. Also has an Evernote migration feature.
Please note, I have no connection to Synology and am not receiving any kind of incentive for this post, I am just a very avid Synology NAS user.
