This backup skill is purpose-aligned and has no network behavior, but it needs Review because it can duplicate private files and metadata into a fixed workspace backup area rather than the destination users provide.
Install only if you are comfortable with a local tool recursively reading and copying the directories you point it at. Use dry-run first, verify the actual backup directory with --status, and avoid broad sensitive paths unless you have checked where backups and manifests will be stored. Treat restore and sync as potentially destructive operations and use --force only after reviewing the listed changes.
