+# Docker Volume Backup Cleanup Role
+
+## Description
+
+This role cleans up failed Docker backups by pulling a [Git repository](https://github.com/kevinveenbirkenbach/sys-ctl-cln-faild-bkps) that contains cleanup scripts and configuring a systemd service to execute them. It ensures that failed or incomplete backups are removed to free up disk space and maintain a healthy backup environment.
+
+## Overview
+
+Optimized for backup maintenance, this role:
+- Clones the sys-ctl-cln-faild-bkps repository.
+- Configures a systemd service to run the cleanup script.
+- Integrates with the [sys-timer](../sys-timer/README.md) role to schedule periodic cleanup.
+- Works in conjunction with the sys-svc-directory-validator role for additional verification.
+
+## Purpose
+
+The primary purpose of this role is to remove failed Docker backups automatically, thereby freeing disk space and preventing backup storage from becoming cluttered with incomplete data.
+
+## Features
+
+- **Repository Cloning:** Retrieves the latest cleanup scripts from a Git repository.
+- **Service Configuration:** Sets up a systemd service to run the cleanup tasks.
+- **Timer Integration:** Schedules periodic cleanup through a systemd timer.
