RepositoryExportDestination / RepositoryImportSource implement the public OCP\UserMigration interfaces on top of the repository, so user_migration's migrators (calendar, contacts, trashbin, account, files) export straight into the encrypted repository. Spike E (NC34): export 0.8s, unchanged second export stores nothing; after deleting the user, import restores account, files (bit-identical), calendar event and contact. Findings: calendars/address books come back as 'migrated-*' with new object URIs; importing over an existing user duplicates contacts and adds a migrated birthday calendar; creating the user on import needs >128 MB (password_policy word list).
NG Backup
Encrypted, incremental backups of Nextcloud with restore from the web interface. Works without shell access: no external programs, no extra PHP extensions beyond sodium.
Status: phase 0 (prototype). Not usable yet. See PLAN.md for the design.
