I have a synology NAS where I backup my photos to. What would be the most cost effective way to encrypt and back up this data without having to purchase another NAS and install it at a family member’s house. It would be about 5 TB and would not touch the data unless my NAS completely takes a crap.
Azure Blob Storage at their Archive tier level is 99c/TB/month, but it’s definitely spendy when you try to extract data from it.
