# Cleanup Backups Service

## Description
|
|

|
|
- Creates a directory for storing cleanup scripts.
|
|
- Deploys a Python script that deletes old backup directories when disk usage is too high.
|
|
- Configures a systemd service to run the cleanup script, with notifications via [sys-ctl-alm-compose](../sys-ctl-alm-compose/README.md).
