So when I upload an image remotely, its back at home within seconds.

The two devices have a bi-directional sync using CloudStation ShareSync. Having two means that when I am at home, I can backup directly to the local NAS, but when I am outside of my home I can upload directly to the off-site NAS which has a much better internet connection. Both have redundant storage, BTRFS filesystems snapshots, frequent backups, and are fully encrypted. One at home, and one off-site on my colocated server (Read about it here). Lets start from the bottom and work our way up Storage Backend storage: Two Synology NAS devices (But could be replaced with anything).Servers: Two Docker containers running OpenSSH.It may seem complicated, but its just building on systems and infrastructure I already have in place, and when you break it down its quite simple. It's very simple to set up, it has strong encryption, and its not some weird proprietary protocol that will disappear or become unsupported any time soon. I tested it to a local SMB share and it seemed to work well enough, so I had to figure out what transfer protocol to use next. I could sync pictures to just about anywhere, and pretty much however I wanted to. I hesitantly (I like free.) bought it, and was surprised at the number of options available. So I looked for a solution, and quite a few people suggested the iOS app PhotoSync ( Link). Others - I think there were other too, I will add them when I remember, but none of them really worked.I also just didn't like Seafile, and I didn't want to the data to be stored within it It seems all of these applications have issues with seeing new pictures. Seafile - I tried the Seafile app together with Seafile, and this too didn't work too well.I tried them anyway, and they all got confused too easily I then would need to keep a Synology NAS for my solution to keep working, which I didn't like. It also means I would need to connect to a VPN all the time while out, or expose my Synology NAS to the internet (Which is a TERRIBLE idea). It also seems like the tools I would use for this seem to change and get replaced over the years. Synology Apps - I tried many of the different Synology solutions, but all of their apps seem quite poorly made, and not very well supported.I did try the app, but it would frequently get confused if I took pictures in quick succession and then deleted them at the destination. It doesn't feel like something that is going to be there forever, and I didn't want to rely on something that may stop working. NextCloud - While I run NextCloud, I don't really like it all too much.There were plenty, but they all had issues too Without using extra software, the pictures would end up on a computer, not my NAS which is backed up.Even with my 26GB of space from referrals, it would get low after taking a long trip and taking a lot of video Even if I am already at home, it relies on my Internets upload speed.I just don't trust cloud storage unless I am the only one holding and controlling the keys. Every single image I would ever take with my phone would be on the internet ready for Dropbox to have a data breach, or for some over-reaching government agency to collect.I had several issues with using Dropbox for this: I used to use Dropbox for getting images from my iPhone, to a computer, but I wanted a better solution. This solution will transfer photos photos from my iPhone to my home NAS automatically (Or manually) based on location, and its all self-hosted and encrypted.
