Depending how important your data is, you may want to consider still backing some of it up to the cloud. You're not going to get the same level of protection with a NAS that you will on the cloud.

I have a decently sized NAS which stores my Plex media and Nextcloud data and will backup Nextcloud daily to Backblaze B2. This way if anything happens to my NAS, I still have my irreplaceable data protected.
