"""
The phone's files backup, as the page runs it (docs/MESHBAY_DESIGN.md §9.13).
Run under Node against the real `drive-sync.js`, which is the photo backup's
own runner (`createBackup` in photo-sync.js) over the files bridge: the same
promises hold, once a day, on an unmetered network, each file under a slot
and read from the phone a range at a time, nothing removed from the node,
and only into a group the account owns alone.
