restic
Install, configure, operate, secure, automate, tune, troubleshoot, and recover restic backups across local, SFTP, S3-compatible, cloud, and REST backends. Use when creating or managing a restic repository, designing backup or retention policy, validating restores, handling repository health or locks, moving repositories, or building safe scheduled backup jobs. Do not use for a generic file-copy task that does not need encrypted, deduplicated snapshots.

What this skill does
Restic Restic is a backup CLI, not a daemon. Treat a scheduled job or service manager as the execution layer. Every usable backup design proves four things: the source was captured, the repository is readable, retention is intentional, and a restore works in a separate target. Operating contract 1. Discover before changing anything: restic version, backend type, repository format, source paths, credentials mechanism, schedule, retention policy, and recovery objective. 2. Keep repository passwords and backend credentials out of command history, logs, templates, and chat. Prefer a root/user-readable password file or a secret manager command over inline values. 3. Before any mutation, confirm target repository, source scope, exclusions, retention groups, schedule, maintenance window, and rollback/recovery path. Read-only discovery may proceed without confirmation. 4. Back up with stable host and tag conventions. Inspect the resulting snapshot, then test a restore into an empty, separate target. A successful backup exit code is not recovery evidence. 5. Treat forget, prune, key remove, rebuild-index, repair, migrate, and backend lifecycle rules as consequential operations. Preview where possible and keep a known-good recovery path. First read-only discovery Set repository location and password source through the environment or command flags before commands that open a repository. Do not export a literal password into a shared shell history. See repository and backend setup. When not to use Do not load this for a one-time unencrypted file copy, a database backup format that restic cannot create, or provider-specific object-storage administration without a restic repository. Use the relevant application backup procedure for consistency, then use this skill to protect its resulting artifacts. …
