Repliqate

Repliqate is a modular backup solution for Docker environments that manages container and volume backups using label-based configuration. It coordinates container states during backup operations to produce consistent snapshots and applies retention rules to stored backups.

Key Features

• Label-based configuration: define backup rules on containers and volumes via Docker labels.
• Container-safe backups: automatically manages container state (pause/stop) to ensure data consistency during backups.
• Flexible scheduling: supports simple schedules (e.g., "@daily 3am") and cron expressions for backup triggers.
• Retention management: per-backup retention settings to automatically prune old backups.
• Runs as a Docker container: designed to operate alongside existing Docker stacks with mounted Docker socket and backup storage path.
• Integrates with established backup tooling: designed to work with backup backends (topics indicate restic integration) and store snapshot data under a configurable host path.

Use Cases

• Regularly scheduled container and volume backups for Docker-based applications to meet recovery SLAs.
• Homelab or small production environments that want label-based, declarative backup rules stored alongside containers.
• Automated retention and pruning of historical backups to limit storage usage.

Limitations and Considerations

• Requires direct access to the Docker socket and host volume paths, which has security implications and requires careful privilege management.
• Built specifically for Docker environments; not targeted at orchestrators like Kubernetes.
• Operates via container/host mounts and labels; advanced storage backends or cloud integration may require additional configuration.

Repliqate provides a pragmatic, label-driven approach to backing up Docker containers and volumes, focusing on consistency and automation through scheduling and retention policies. It is suited for users who prefer declarative backup rules that live with container configuration.
