Cleanup Backups Service¶
Description¶
This role automates the cleanup of old backups by executing a Python script that deletes outdated backup versions based on disk usage thresholds. It ensures that backup storage does not exceed a defined usage percentage.
Overview¶
Optimized for effective disk space management, this role:
Installs required packages (e.g. lsof and psutil) using pacman.
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.
