Backup Types

docker-backup supports multiple backup types, each designed for specific applications. The backup type is specified using the docker-backup.<name>.type label.

Type Description Output

volume Docker volume backup .tar.zst

How Backup Types Work

Each backup type:

  1. Validates the container configuration (required environment variables, etc.)
  2. Executes the appropriate backup command inside the container
  3. Streams the output to storage (with optional compression)
  4. Supports restoration from backup files

Choosing a Backup Type

Select the backup type that matches your application:

Application Backup Type
PostgreSQL postgres
MySQL mysql
MariaDB mysql
Generic file data volume
