Docker containers backup

Back up databases running inside Docker containers without exposing them to external ports.

SimpleBackups can connect directly to Docker containers on your server to back up MySQL, PostgreSQL, MongoDB, or Redis databases. You do not need to map container ports to the host — SimpleBackups detects running containers and connects to the database inside them.

Connect your server

Before creating a backup, connect the server running your Docker containers to SimpleBackups. See Connect your server for instructions.

Create the backup

1. Go to Create Backup and select your server from the Own Server section

2. Click Select a Docker Container. SimpleBackups will fetch your running containers — select the one containing the database you want to back up

3. Click Save and fill in your database connection parameters. The default host inside the container is 127.0.0.1 or localhost

4. Complete your backup options (name, schedule, retention, storage) and click Create Backup

+Tip

If your Docker database is on a private network and you want to avoid using a bastion host, you can use Tailscale to establish a secure connection. See Connecting a private database for details.
