# backup/backup_primary.sh — Create a full Gitea backup (dump) and store on Fedora
|
|
# Depends on: Phase 1 complete (Gitea running on Unraid)
|
|
#
|
|
# What's in the dump:
|
|
# - SQLite database (users, tokens, SSH keys, OAuth, webhooks, org/team, issues)
|
|
# - All git repositories
|
|
# - app.ini config
|
|
#
|
|
# Steps:
|
|
# 1. Run `gitea dump` inside the container to create a zip archive
|
|
# 2. SCP the dump from Unraid to Fedora (offsite storage)
|
|
# 3. Clean up the dump from Unraid /tmp
|
|
# 4. Prune old backups beyond retention count
|
|
# 5. Print backup summary
|

# Step 1: Run gitea dump inside the container
|
|
# The -u git flag is important — gitea dump must run as the git user who
|
|
# owns the repository files. The dump is created in /tmp inside the container
|
|
# which maps to /tmp on the host via the default Docker tmpfs mount.

|
|
# a relay is more reliable with our existing SSH config.
