+# `gitea dump` doesn't currently back up LFS data as well, only git repos
+# It primarily backs up the SQL DB, and also the config / logs
+# We'll backup like this:
+#   * "gitea dump" to backup the DB and config etc
+#   * tar / bzip all the repos since they will be skipped
+#     * Not rotated because git data is immutable (normally) so has all data
+#   * rsync LFS data directly from /volume/docker/gitea/git/lfs
+#     * No need for rotation since all files are immutable
+# 
+# This means our backup folder will contain:
+#   * /gitea_data.zip - containing the gitea data
+#   * /repositories/ - containing the bundles, structured owner/name.bundle
+#   * /lfs/ - containing all the direct LFS data
