# Backup expiration logic
The script automatically deletes old backups using the following logic:
- Within the last 24 hours, all the backups are kept.
- Within the last 31 days, the most recent backup of each day is kept.
- After 31 days, only the most recent backup of each month is kept.
- Additionally, if the backup destination directory is full, the oldest backups are deleted until enough space is available.
