Friends' Backup

version 0.23 - 2017-01-01 (needs Java 1.8+)

This is absolute beta. It works but protocols and storage format could change in new versions


This software is a free alternative to commercial online backups. Make backup onto your friends computer. You can also choose to do backup on computers in your home network.

It is a real backup, not just a file copy, meaning you can recover from any point in time. E.g. find a file you deleted 1 year ago. Dropbox (free edition) only stores deleted files and version history 30 days back.

All files are encrypted (128 bit AES) before leaving the computer so destination could be anywhere. Add multiple friends to gain redundant backup. Each endpoint decides how much disk space a friend may use.

The program is both a client and a server so connections will be attempted in both directions. The backup will transfer files compressed, de-duplicated and encrypted to your friend's location. If the connection is dropped or your friend is offline it will continue when connected again.

Quick Start

First, you link with your friend (your friend will do the same). You'll have to exchange access keys.

Create a backup. Choose friend, add folders and pick a password for encryption
