Daily 'forgejo dump' (tar.zst) to /opt/backups/forgejo with 14-day retention, via a oneshot service + timer. Maintenance section now documents both backup layers (Codeberg push-mirror for git, dump timer for full state). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# forgejo-backup.sh — dump the live Forgejo instance and copy the archive to
|
|
# the host. Run on the VPS via forgejo-backup.timer (see this dir).
|
|
#
|
|
# `forgejo dump` produces a single archive of the database, repositories,
|
|
# config, and the data dir (attachments + the container registry blobs). It is
|
|
# safe to run against a live instance.
|
|

|
|
# Install:
|
|
# sudo install -m 0755 forgejo-backup.sh /usr/local/bin/forgejo-backup.sh
