-# JARVIS backup — DB dump as tar.gz, admin-panel compatible
+# JARVIS backup — DB dump + all files needed to actually restore JARVIS, as tar.gz
+# Fixed 2026-07-07: this only ever backed up the MySQL database. If this VM were
+# lost, the DB alone is useless without the application code, the reactor daemon,
+# its systemd unit, and the nginx site config — none of which were captured. Also
+# fixed a typo ($SIYE -> $SIZE) that silently broke the size line in the log.
