The administrator's page backs up, downloads, uploads and restores

Browse Source 
/clientapi/admin/backups (owner decision 2026-10-07, approving these endpoints in production): the list with what runs,
the restore waiting and the last restore's report; back up now; delete; a download for the password, through a ticket
good for ten minutes in the link's path, as one tar whose length is known first and which honours Range (BackupTar);
an upload in pieces of at most 32 MB, each at the offset already received or refused with it, so a broken upload
resumes, read into a backup only when it holds nothing but plain files under one backup's folder; and a restore for
the password and the host typed out. Every call checks the administrator against the database. nginx streams downloads
for an hour and takes upload pieces unbuffered, rate-limited.
