Hello everyone.
I want to share with you Syncthing
https://syncthing.net/
Title is probably misleading, as Syncthing is not a "cloud" like owncloud or
nextcloud.
It is a program that is way more easy to install and configure. It has
clients for GNU/Linux and F-Droid.
Think of Syncthing as your private torrents, which no one can see and get
synchronized automatically.
You don't need an http domain or do port forwarding on your router, like
owncloud and nextcloud require.
You just install, and you use the generated number for your device to sync
with your other devices.
The connection between devices is peer-to-peer.
For example, your phone and your laptop can sync, even if your work pc is
off.
The same way, your work pc and your phone can sync, even if your laptop is
off.
There is no need for a server.
Connections have encryption, authenticated and private, so no need to worry
about a third party looking at your data.
It is also really easy to use, and choose what directories you want to sync,
with what device.
You can also save versions of your data, so even if you delete something or
change it by accident, you can easily find an older version.
I hope this is useful for you :)
