There are many options for creating backups. Some solutions have extensive user interfaces or features such as encryption, compression, deduplication and block level incremental backup. A nice open source example of this is Duplicati.
I chose a simple setup with Rclone because it fits my needs well. Rclone can synchronize files from your computer to any of the common cloud storage providers. It can also perform two way synchronization, allowing you to mirror folders across computers. There are many more features listed on the website.
For storage, Backblaze B2 is reliable and secure while still being cheap. Anything under 10GB is free, and 100GB costs 50 cents per month. B2 has a native ability to keep old versions of files, and the retention policy for old versions is highly configurable.
You can turn on transparent encryption in the bucket settings.
The third piece of the puzzle is a way to run Rclone on a schedule. There are two great options for this, cron jobs and systemd timers. A systemd timer is a more modern solution that can be configured to run periodically based on the time that the last backup job finished.
These services make setup and usage simple while still having all the features I want:
- Low cost
- Ability to browse backup files from any phone or computer
First, install Rclone. It can be found in most package managers. Then you'll have to configure your remote. If you choose Backblaze B2, create a bucket and generate a new application key to use with Rclone. Add the remote with rclone config.
Next, create a backup script that runs Rclone and specifies the folders you want to back up. I placed my script at
Give the script executable permissions with
chmod +x. Don't forget to test your script when you think it's ready.
Finally, you'll need to set up systemd. Create a systemd service file at
Then create a timer at
/etc/systemd/system/rclone.timer. Further documentation can be found here.
After saving these files, you may need to run:
sudo systemctl daemon-reload
Make the timer start on boot by enabling the timer:
sudo systemctl enable rclone.timer
Start the timer now with:
sudo systemctl start rclone.timer
The backup script should run once and the timer will trigger it again in 15 minutes. You can check the timer status with:
sudo systemctl status rclone.timer

You can also check the status of the service with:
sudo systemctl status rclone.service
rclone.service - RClone Backup Loaded: loaded (/etc/systemd/system/rclone.service; static) Active: inactive (dead) since Wed 2021-06-16 13:41:10 PDT; 6min ago TriggeredBy: rclone.timer Process: 51857 ExecStart=/usr/local/bin/rclone-backup.sh (code=exited, status=0/SUCCESS) Main PID: 51857 (code=exited, status=0/SUCCESS) CPU: 1.248s rclone-backup.sh: INFO: There was nothing to transfer rclone-backup.sh: Checks: 476 / 476, 100% systemd: rclone.service: Deactivated successfully. systemd: rclone.service: Consumed 1.248s CPU time
If you want to manually run a backup at any time, just start the service manually:
sudo systemctl start rclone.service
