f/backup: backup folders

f/backup (and its free version: f/backup Lite) is a backup software that lets you select a source folder and make a copy/mirror of its content to a destination folder, with optional filters to exclude unwanted files. These backups can handle data located on:

- Your device
- An external storage (MicroSD for example)
- A network share
- An FTP or FTPS server (without TLS session reuse)
- An SFTP server
- A WebDAV server

As the name implies, f/backup is a backup only software and does NOT do synchronization. Your backups will never modify their source folders, keeping the app as easy to use and understand as possible and preventing unexpected data loss.

Initially developed as a personal backup project for my family, relatives, and I, f/backup progressively evolved for the last year and a half to a point where I thought it could potentially fill other people’s needs.

Cloud subscription cost and privacy concerns were the deciding factors that motivated me to start this project. As consequence, your private information/data are none of my business and f/backup will never try to spy on you.

In terms of security, your server address, login, and password are encrypted with a random AES-256 key within the database. You can also lock backup edition behind a biometric security prompt to prevent unauthorized users to check/change your settings.

f/backup is designed to be fully automated if you desire so with the ability to schedule your backups. For battery consumption concerns, it won’t wake-up your device from deep sleep and can delay your scheduled backup until your device is ready if necessary.

As for performance, it is a multithreaded app. It can handle up to 5 files in parallel per backup and run an unlimited number of backups at once.

I’m unfortunately unable to try every combination of device/server and even though I didn’t encounter issue during my testing and daily usage, incompatibilities may occur. Feel free to contact me if you notice something wrong, I’ll do my best to resolve the problem.
