The Automatic Backup Cleanup option located in Settings > ShortPixel > Processing tab helps save disk space by automatically deleting old image backups after a selected period.
To use it:
- Enable Automatic backup cleanup.
- Under Delete backups older than, choose a retention period.
- Save your settings.
Backups older than the selected period will be permanently removed. Once deleted, they cannot be restored through the plugin, so keep a separate copy of any originals you may need later.
