//! Implements the `manta backup vcluster` command.
//!
//! Drives `POST /api/v1/migrate/backup` to dump a cluster's BOS / CFS
//! / HSM / IMS state to a destination folder on the server. Runs an
//! optional pre-hook before the POST and a post-hook after. The hook
//! perms are validated up-front so a misconfigured hook never blocks
//! mid-backup. Inverse of [`super::super::restore::vcluster`].
