By default, ONCE pauses the application container when taking a backup. This guarantees a consistent snapshot of the data, but for a large installation and/or a slow destination path (like a network mount), that pause could be a bit disruptive to live traffic. But ONCE also support a pause-free path: if a `pre-backup` hook is present in the container, ONCE will run that and skip the pause. So by supplying necessary hooks, we can avoid any disruption from backups. - `pre-backup` runs the existing script/admin/prepare-backup, which uses SQLite's online backup API to get a consistent snapshop. - `post-restore` moves our snaphotted file back into place, and removes the orphaned sidecar files
