+# Encrypted Hermes Backup Pipeline
+
+Issue: `timmy-home#693`
+
+This pipeline creates a nightly encrypted archive of `~/.hermes`, stores a local encrypted copy, uploads it to remote storage, and supports restore verification.
+
+## What gets backed up
+
+By default the pipeline archives:
+
+- `~/.hermes/config.yaml`
+- `~/.hermes/state.db`
+- `~/.hermes/sessions/`
+- `~/.hermes/cron/`
+- any other files under `~/.hermes`
+
+Override the source with `BACKUP_SOURCE_DIR=/path/to/.hermes`.
+
+## Backup command
+
+```bash
+BACKUP_PASSPHRASE_FILE=~/.config/timmy/backup.passphrase \
+BACKUP_NAS_TARGET=/Volumes/timmy-nas/hermes-backups \
+bash scripts/backup_pipeline.sh
+```
+
+The script writes:
+
+- local encrypted copy: `~/.timmy-backups/hermes/<timestamp>/hermes-backup-<timestamp>.tar.gz.enc`
+- local manifest: `~/.timmy-backups/hermes/<timestamp>/hermes-backup-<timestamp>.json`
+- log file: `~/.timmy-backups/hermes/logs/backup_pipeline.log`
+
+## Nightly schedule
+
+Run every night at 03:00:
+
+```cron
+0 3 * * * cd /Users/apayne/.timmy/timmy-home && BACKUP_PASSPHRASE_FILE=/Users/apayne/.config/timmy/backup.passphrase BACKUP_NAS_TARGET=/Volumes/timmy-nas/hermes-backups bash scripts/backup_pipeline.sh >> /Users/apayne/.timmy-backups/hermes/logs/cron.log 2>&1
+```
+
+## Remote targets
+
+At least one remote target must be configured.
+
+### Local NAS
+
+Use a mounted path:
+
+```bash
+BACKUP_NAS_TARGET=/Volumes/timmy-nas/hermes-backups
+```
+
+The pipeline copies the encrypted archive and manifest into `<BACKUP_NAS_TARGET>/<timestamp>/`.
+
+### S3-compatible storage
+
+```bash
+BACKUP_PASSPHRASE_FILE=~/.config/timmy/backup.passphrase \
+BACKUP_S3_URI=s3://timmy-backups/hermes \
+AWS_ENDPOINT_URL=https://minio.example.com \
+bash scripts/backup_pipeline.sh
+```
+
+Notes:
+
+- `aws` CLI must be installed if `BACKUP_S3_URI` is set.
+- `AWS_ENDPOINT_URL` is optional and is used for MinIO, R2, and other S3-compatible endpoints.
+
+## Restore playbook
+
+Restore an encrypted archive into a clean target root:
+
+```bash
+BACKUP_PASSPHRASE_FILE=~/.config/timmy/backup.passphrase \
+bash scripts/restore_backup.sh \
+  /Volumes/timmy-nas/hermes-backups/20260415-030000/hermes-backup-20260415-030000.tar.gz.enc \
+  /tmp/hermes-restore
+```
+
+Result:
+
+- restored tree lands at `/tmp/hermes-restore/.hermes`
+- if a sibling manifest exists, the restore script verifies the archive SHA256 before decrypting
+
+## End-to-end verification
+
+Run the regression suite:
+
+```bash
+python3 -m unittest discover -s tests -p 'test_backup_pipeline.py' -v
+```
+
+This proves:
+
+1. the backup output is encrypted
+2. plaintext archives do not leak into the backup destinations
+3. the restore script recreates the original `.hermes` tree end-to-end
+4. the pipeline refuses to run without a remote target
