Theoretically yes, but in practice it is a different case. I have hope.

Syncthing is fine but battery drain

I used to use it, but my phone model isn't famous because of it battery, sadly.

Remotely-save with S3 (minio or the like) seems pretty good so far.

LiveSyn can use S3 too insead of Couchdb but I will give a look to remotely-save.

I have been rethinking about what you said. But, I have some questions:
Do LiveSync handles version control (Like Obsidian-Git or the official sync)?
If not, Do you use or know about a compatible tool or something?

Could I use Git for backups and version control (In one device) and LiveSync for synching with my other devices?
(I know you said,
> but ok with not having git

But I still wonder if there is a way to do it. Where do they fail working togheter? )

EDIT:
Can we use github plugin to backup our vault along with livesync plugin? #232

I've been watching it since it launch, but Git version control and hosting is better for my use case.

Can it merge files in conflict?
