package backup

// This file bridges the backup package to internal/appbackup, where the
// self-contained app-data backup primitives (DB dump, Docker-volume archive
// discovery, keep-side path helpers) now live. The backup package keeps these
// names available — via type/const aliases and thin function forwarders — so
// the (still present) delete-side code and the both-side consumers (web, api,
// report) compile unchanged. Behaviour is identical: the forwarders call
// straight through to appbackup.
//
// Go has no function aliasing, so the functions are one-line forwarders while
// the types/consts use real aliases.
