# `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
|
|
#
|

# Stop on errors
