Automate Backups with Duplicati and Docker

Cech Tech Reviews

Set up automated, encrypted backups of your important files to cloud storage or a local NAS. Never lose data again.

1. 1

   Run Duplicati in Docker

   docker run -d \
     --name duplicati \
     --restart unless-stopped \
     -p 8200:8200 \
     -v ~/duplicati/config:/config \
     -v ~/duplicati/backups:/backups \
     -v /path/to/your/data:/source:ro \
     lscr.io/linuxserver/duplicati:latest

2. 2

   Open the web interface

   Go to /:8200. The setup wizard walks you through creating your first backup job.

3. 3

   Choose your backup destination

   Duplicati supports local folders, network drives, S3, Google Drive, Backblaze B2, OneDrive, and more. Pick what works for your setup.

4. 4

   Set a schedule and encryption

   Configure daily backups at a time your computer is on. Enable AES-256 encryption with a strong passphrase. Your data is encrypted before it leaves your machine.

5. 5

   Test a restore

   A backup you have never tested is not a backup. After the first run, try restoring a single file to verify everything works.
