rustcopy-flow

Use this Skill to plan the rustcopy command, run it with --dry-run first, and review the JSON report before confirming real execution. The agent never adds --force-purge or skips the dry-run on its own, so destructive options like --mirror always require your explicit approval.

The Skill builds a rustcopy command with --backup-type full, incremental, or differential plus --keep-generations N. Retention rotates by cycle (a full plus its dependents), and the Skill shows exactly which old cycles would be deleted and asks for confirmation before any purge.

The rustcopy binary compiles on Linux and macOS for comparison, reporting, and verification logic, but real transfers require robocopy.exe, which exists only on Windows. On non-Windows systems the Skill limits itself to planning, dry-runs, and report reading and tells you so explicitly.

The Skill installs a Task Scheduler entry via --install-schedule using specs like daily@HH:MM, hourly@N, or weekly@DAY@HH:MM. It shows the exact command that will run at each trigger before installing, and notes that the Windows service option is idle infrastructure, not a scheduler.

Exit code 3 means the mirror safety check aborted the purge because unexpected differences were found between source and destination. The Skill will not retry with --force-purge automatically; it shows you what would be deleted and asks for explicit confirmation first.

Add --webhook-url to the backup command to post a notification to an HTTP endpoint you own. For multi-channel fan-out, the optional feature-gated notify-server binary supports ntfy and generic webhooks, and the Skill verifies end-to-end delivery with a small real test backup.
