# Backup NexusOS to the router. All modes rsync into the canonical nexus-core
|

# folder over the normal SSH daemon (host: router, port 9001) — the SAME folder
|

# restore.sh pulls from, so backup and restore stay in sync.

# Backup NexusOS via git → Gitea (enderofwings/NexusOS). Replaces the old
|
||||
# rsync-to-router backup. Commits the tracked tree (source, config, playbooks,
|
||||
# branding, docs) plus a SQL dump of the memory DB, then pushes to the remote —
|
||||
# so a fresh clone + restore.sh fully rebuilds the machine.
|
||||
#
|
||||
# backup.sh Fast incremental backup.
|
||||
# backup.sh full Same, but first snapshots the live desktop wiring
|
||||
# and retains runtime/ (minus logs) for a fuller copy.
|
||||
# backup.sh -c | --claude Dry-run: show what a backup WOULD push (content-
|
||||
# level), change nothing. For deciding whether an
|
||||
# actual backup is needed.
|
||||
# backup.sh Commit changed files + push.
|
||||
# backup.sh full | -f Also snapshot live desktop wiring + Claude notes first.
|
||||
# backup.sh -c | --claude Dry-run: show what a backup WOULD commit/push. No changes.

#
|
||||
# The regenerable heavies (Promethean venv, ollama binary, models/, node_modules,
|

# dist, runtime logs) are intentionally NOT backed up — restore.sh rebuilds them
|

# from requirements-*.txt / package-lock.json / `ollama pull`.
