# Git Auto-Sync Setup for Second Brain
|
||||
|
||||
Automatically sync vault changes between server, desktop, and phone using Git.
|
||||
|
||||
## How It Works
|
||||
|
||||
```
|
||||
Desktop/Phone Changes → Git Repo ← Server Auto-Commits
|
||||
↓
|
||||
All devices sync
|
||||
```
|
||||
|
||||
## Server Setup
|
||||
|
||||
### 1. Install Auto-Sync Service
|
||||
|
||||
```bash
|
||||
sudo cp /workspace/second-brain/git-auto-sync.service /etc/systemd/system/
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl enable git-auto-sync.service
|
||||
sudo systemctl start git-auto-sync.service
|
||||
|
||||
# Verify
|
||||
sudo systemctl status git-auto-sync.service
|
||||
```
|
||||
|
||||
### 2. Watch Auto-Commits
|
||||
|
||||
```bash
|
||||
# View logs
|
||||
sudo journalctl -fu git-sync
|
||||
|
||||
# Example output:
|
||||
# [2026-04-26 07:45:30] Changes detected:
|
||||
# M 03-learnings/architecture.md
|
||||
# A 00-inbox/new-idea.md
|
||||
# ✓ Committed
|
||||
# ✓ Pushed to remote
|
||||
```
|
||||
|
||||
## Desktop Setup
|
||||
|
||||
### 1. Clone the Vault
|
||||
|
||||
```bash
|
||||
# First time
|
||||
git clone ssh://user@server:/workspace/second-brain ~/Obsidian/second-brain
|
||||
|
||||
# Or if using Local Sync, configure it to pull from this git repo
|
||||
```
|
||||
|
||||
### 2. Pull Latest Changes
|
||||
|
||||
```bash
|
||||
cd ~/Obsidian/second-brain
|
||||
git pull
|
||||
```
|
||||
|
||||
### 3. Auto-Pull (Optional)
|
||||
|
||||
**macOS/Linux:**
|
||||
```bash
|
||||
# Add to crontab (every 5 minutes)
|
||||
crontab -e
|
||||
*/5 * * * * cd ~/Obsidian/second-brain && git pull -q 2>/dev/null
|
||||
```
|
||||
|
||||
**Or use a Git hook:**
|
||||
```bash
|
||||
cat > .git/hooks/post-merge << 'EOF'
|
||||
#!/bin/bash
|
||||
# Auto-sync after merge
|
||||
echo "✓ Vault synced"
|
||||
EOF
|
||||
chmod +x .git/hooks/post-merge
|
||||
```
|
||||
|
||||
## Phone Setup
|
||||
|
||||
### With Obsidian + Local Sync Plugin
|
||||
|
||||
1. **On Server:**
|
||||
- Make sure git repo is accessible (or use Gitea)
|
||||
|
||||
2. **On Phone:**
|
||||
- Install "Local Sync" plugin in Obsidian
|
||||
- Configure it to sync with: `ssh://user@server:/workspace/second-brain`
|
||||
- Or configure with Gitea URL
|
||||
|
||||
3. **On Desktop:**
|
||||
- Same setup, pull regularly
|
||||

|
||||
## Sync Strategies
|
||||
|
||||
### Strategy 1: Git-Only (Recommended)
|
||||
|
||||
- Server auto-commits all changes
|
||||
- Desktop: `git pull` manually or via cron
|
||||
- Phone: Local Sync pulls from server git
|
||||
|
||||
```bash
|
||||
# Desktop cron (every 5 min)
|
||||
*/5 * * * * cd ~/Obsidian/second-brain && git pull -q
|
||||
```
|
||||
|
||||
### Strategy 2: Obsidian + Local Sync
|
||||
|
||||
- Desktop + Phone: Use Obsidian's Local Sync plugin
|
||||
- Server: Git auto-sync mirrors changes
|
||||
|
||||
**Advantage:** Real-time sync on devices, server keeps git history
|
||||
|
||||
### Strategy 3: Git + SSH Pull
|
||||
|
||||
- Desktop/Phone: SSH git clone
|
||||
- Pull before opening Obsidian
|
||||
- Push changes after editing
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# pre-open-obsidian.sh
|
||||
cd ~/Obsidian/second-brain
|
||||
git pull
|
||||
open ~/Obsidian/second-brain # macOS
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Remote Repository (Gitea / GitHub)
|
||||
|
||||
### Configure Remote Push
|
||||
|
||||
**If using Gitea on your server:**
|
||||
|
||||
```bash
|
||||
# On server
|
||||
cd /workspace/second-brain
|
||||
git remote add gitea ssh://git@gitea-server/your-repo.git
|
||||
|
||||
# Verify
|
||||
git remote -v
|
||||
|
||||
# Push existing commits
|
||||
git push -u gitea master
|
||||
```
|
||||
|
||||
**Then on desktop/phone:**
|
||||
|
||||
```bash
|
||||
git clone ssh://git@gitea-server/your-repo.git
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Monitoring Syncs
|
||||
|
||||
### View Recent Commits
|
||||
|
||||
```bash
|
||||
cd /workspace/second-brain
|
||||
git log --oneline -10
|
||||
```
|
||||
|
||||
### Check Sync Status
|
||||
|
||||
```bash
|
||||
# See what's staged but not committed
|
||||
git status
|
||||
|
||||
# See changes in last hour
|
||||
git log --since="1 hour ago" --oneline
|
||||
```
|
||||
|
||||
### Manual Sync Test
|
||||
|
||||
```bash
|
||||
# On desktop: make a change
|
||||
echo "test" >> 00-inbox/test.md
|
||||
git add .
|
||||
git commit -m "Test sync"
|
||||
git push
|
||||
|
||||
# On server: should auto-pull (if configured)
|
||||
cd /workspace/second-brain
|
||||
git log --oneline -1
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Conflict Resolution
|
||||
|
||||
If both server and desktop edit the same file:
|
||||
|
||||
```bash
|
||||
# Server (auto-sync) will get it first
|
||||
# Desktop pulls and sees conflict marker:
|
||||
|
||||
<<<<<<< HEAD
|
||||
desktop version
|
||||
=======
|
||||
server version
|
||||
>>>>>>> origin/master
|
||||
|
||||
# Manually resolve, then:
|
||||
git add .
|
||||
git commit -m "Resolved conflict"
|
||||
git push
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Disable Auto-Sync (if needed)
|
||||
|
||||
```bash
|
||||
sudo systemctl stop git-auto-sync.service
|
||||
sudo systemctl disable git-auto-sync.service
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Performance Notes
|
||||
|
||||
- **Poll interval:** 30 seconds (adjustable)
|
||||
- **Commit overhead:** ~50ms per check
|
||||
- **Memory:** ~64MB (limited)
|
||||
- **CPU:** ~10% max
