θ = atan2(sin(Δlong).cos(lat2), | |
cos(lat1).sin(lat2) − sin(lat1).cos(lat2).cos(Δlong)) |

# `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 |
