+# Standardized data backup helpers for update_script(). They replace the
+# hand-rolled "cp/mv to a sibling dir, update, copy back, rm" dance that is
+# duplicated across the ct/*.sh update functions.
+#
+# create_backup <path> [<path> ...]
+#   - Copies each given file/directory into a persistent store at
+#     /opt/<NSAPP>.backup, mirroring its absolute path inside the store, and
+#     records it in a manifest so restore_backup needs no arguments.
+#   - Idempotent: if a store from a previous (failed) run already exists, it is
+#     left untouched and no new backup is taken. This keeps the last-known-good
+#     data instead of overwriting it with now-partially-updated data on retry.
+#   - Missing source paths are skipped with a warning (not fatal).
+#   - Aborts the update on copy failure: if any file/dir cannot be backed up,
+#     the half-written store is removed and the script exits, so the update
+#     never runs against unprotected data (and a retry re-attempts a clean
+#     backup rather than skipping it).
+#
+# restore_backup
+#   - Copies every path recorded in the manifest back to its origin (replacing
+#     whatever the update left there), then deletes the store.
