Your requirement for a mobile iOS app makes it harder so I’ll go non-free software with my suggestion: Tap Forms. Offline first, iCloud sync, macOS and iOS apps. But no Android or Windows apps.

If you wanna keep it self-hosted, these services need an internet connection anyway, even Airtable. Just go with a Web based one that has good mobile layout.

If you have an offsite copy of your files (and not in a sync service like Dropbox) you are already in a better position than most.

Restoring from offsite takes time, even with Backblaze’s option of shipping a hard disk. You may also have data corruption troubles, companies may close all of sudden. It’s just not as convenient as local copies.

A further copy that is locally available is simply a better strategy. Adding more copies after these two is not a bad idea but you start getting hit by the law of diminishing returns.

You can actually read more about the 3-2-1 rule in a Backblaze post: https://www.backblaze.com/blog/the-3-2-1-backup-strategy/

hoppy.network seems like a very expensive Wireguard provider ($8/month for 1TB@100mbit). For that purpose one can spend half that for a VPS with gigabit speeds, even a quarter that during promotions. That provides the same services plus whatever else you can fit to it. What am I missing that they provide?

In case nginx does not work out for you, you can opt for more generic reverse proxies. frp is my favorite one: https://github.com/fatedier/frp

Same, I would actually be curious to listen to a right wing tech podcast as the two concepts clash so hard in my brain.

I have self-hosted my own emails many times. Up to having three SMTP servers with failsafe option at DNS.

It’s super nice, but I would never self-host SMTP again. It’s a nightmare. I had to email or open a ticket at most ISPs despite my clean IPs. Most ISPs simply blacklist all IPs unless they are major email providers already.

My advice is go for it but let SMTP be handled by who will deal with these frustrations. MXroute is a great choice and it’s cheap.

I use https://github.com/bastienwirtz/homer because it is dead simple to configure, and I protect it with HTTP auth at the reverse proxy level.

The development never stalled and the app has already improved. You need to access a new TestFlight link. See their latest post: https://lemmy.ml/post/1550828

In some cases outbound only, in other cases inbound, too, with redirect somewhere else. I’m not using them to store emails right now.

MXroute. First, because Jar is stupid (hope someone will get the reference). Second, because they are awesome and cheap at the same time. You can go from full-fledged hosting with them to using them as relay, and for pizza money for a year.
