Obsidian GitHub Sync

Automated synchronization of Obsidian vault with GitHub repository using git with conflict detection.

Features

  • Automatic sync: git pull --rebase → commit → push
  • Conflict detection: Detects and flags merge conflicts
  • Configurable: Environment variable based configuration
  • Notification: Optional conflict notifications
  • Safe: Uses rebase to maintain clean history

Quick Start

1. Set Environment Variables

export OBSIDIAN_VAULT_DIR="/path/to/your/obsidian-vault"
export GITHUB_REMOTE_URL="git@github.com:username/repo.git"

2. Run Initial Sync

./scripts/obsidian-sync.sh

3. Setup Auto-sync (Cron)

# Daily at 3 AM
0 3 * * * /path/to/scripts/obsidian-sync.sh

# Check conflicts at 9 AM
0 9 * * * /path/to/scripts/check-conflict.sh

Scripts

obsidian-sync.sh

Main synchronization script. Located at scripts/obsidian-sync.sh.

What it does:

  1. Checks for uncommitted changes and commits them
  2. Pulls from GitHub with --rebase
  3. Pushes to GitHub
  4. Creates conflict flag if rebase fails

Environment Variables:

  • OBSIDIAN_VAULT_DIR (required): Path to Obsidian vault
  • GITHUB_REMOTE_URL (required): GitHub repository URL
  • GIT_USER_NAME (optional): Git user name
  • GIT_USER_EMAIL (optional): Git user email
  • SYNC_LOG_FILE (optional): Log file path (default: /tmp/obsidian-sync.log)
  • CONFLICT_FLAG_FILE (optional): Conflict flag path (default: /tmp/obsidian-sync-conflict.flag)

check-conflict.sh

Conflict checking script. Located at scripts/check-conflict.sh.

What it does:

  • Checks if conflict flag file exists
  • Outputs conflict details if found
  • Returns exit code 1 on conflict, 0 on clean state

Workflow

Normal Sync Flow

User modifies notes in Obsidian
        ↓
Cron runs obsidian-sync.sh at 3 AM
        ↓
Auto-commit local changes
        ↓
git pull --rebase origin master
        ↓
git push origin master
        ↓
Sync complete ✓

Conflict Flow

Sync runs
    ↓
pull --rebase fails (remote has divergent changes)
    ↓
Create conflict flag file
    ↓
Exit with error
    ↓
Morning check-conflict.sh detects flag
    ↓
Notify user
    ↓
User resolves conflicts manually
    ↓
Re-run sync

Handling Conflicts

When conflicts occur:

  1. Check conflict flag file location (default: /tmp/obsidian-sync-conflict.flag)
  2. Navigate to vault directory
  3. Resolve conflicts using standard git workflow:
cd $OBSIDIAN_VAULT_DIR
git status                    # See conflicted files
# Edit files to resolve conflicts
git add -A                    # Stage resolved files
git rebase --continue         # Complete rebase
git push origin master        # Push resolved state

Configuration Reference

See references/setup-guide.md for detailed setup instructions including:

  • SSH key configuration
  • Multi-device sync best practices
  • Troubleshooting guide
  • Cron setup examples

Integration Examples

With OpenClaw

# Add sync cron job
openclaw cron add --name "obsidian-sync" \
  --cron "0 3 * * *" \
  --command "/path/to/obsidian-sync.sh"

# Add conflict check
openclaw cron add --name "obsidian-check" \
  --cron "0 9 * * *" \
  --command "/path/to/check-conflict.sh"

With Systemd (Linux)

Create ~/.config/systemd/user/obsidian-sync.service:

[Unit]
Description=Obsidian Vault Git Sync

[Service]
Type=oneshot
Environment="OBSIDIAN_VAULT_DIR=/path/to/vault"
Environment="GITHUB_REMOTE_URL=git@github.com:user/repo.git"
ExecStart=/path/to/obsidian-sync.sh

Create ~/.config/systemd/user/obsidian-sync.timer:

[Unit]
Description=Run Obsidian sync daily at 3 AM

[Timer]
OnCalendar=*-*-* 03:00:00
Persistent=true

[Install]
WantedBy=timers.target

Enable:

systemctl --user daemon-reload
systemctl --user enable obsidian-sync.timer
systemctl --user start obsidian-sync.timer

Best Practices

  1. Close Obsidian during sync to avoid file lock issues
  2. Commit regularly in Obsidian to reduce conflict chances
  3. Sync before switching devices
  4. Use .gitignore to exclude Obsidian's cache files:
# Obsidian
.obsidian/workspace.json
.obsidian/workspace-mobile.json
.obsidian/plugins/*/data.json
.trash/
