stingle-photos-android VS Duplicacy

Stingle Photos (version 2.11.0): Stingle Photos is a secure, end-to-end encrypted gallery and sync app

Also remembered, you have Stingle Photos too.

It's basically a backend server for Stingle.

c2FmZQ surely has a terrible name but I guess it ticks all of your points otherwise. It is a fork of Stingle. I only see one issue: while the Android app is available with selfhosting patches, you probably would have to update and build the iOS app by yourself.

I used it years ago. Now I use Stingle.

Try Stingle, The most private E2EE cloud storage( photos + vids only) that I have personally known. They even provide 1GB storage for free.

You can use Stingle Photos (Website, App Store), they offer 1GB free backup and unlimited (or limited to device capacity) photo encryption. Their servers are in the US but you don't have to use them if you only encrypt

I have been having great luck with incremental backups with the very similar named Duplicacy https://duplicacy.com/

Pro: No need for a special index database. The chunks are placed in the file system. This explains it in greater detail. Seems to place great emphasis on reliability, which is important for me. Versioning is also supported.

Having all your data in one place isn't wise though, so I am planning on storing encrypted backups on Dropbox and Backblaze B2 using Duplicity so that I am following the 3-2-1 backup rule.

I tried a bunch of different ways but ultimately settled on Duplicacy [0].

It runs inside a Docker container and backs up both my data as well as configurations like my docker compose file and smb.conf.

Off site storage was Backblaze B2, but I moved to Hetzner. Likely will move back just because B2 is cheaper and a bit faster for my region.

Another layer of backup I do is use Duplicacy to backup to a portable hard drive occasionally that I keep off site.
