## Installation Steps
|
||||
|
||||
### Current Step: Configure and Test Backup
|
||||
|
||||
1. **Install backup scripts** ✅ Done
|
||||
```bash
|
||||
# Scripts installed to /usr/local/bin/
|
||||
# backup-setup, backup-full, backup-home, backup-incremental, backup-configs
|
||||
```
|
||||
|
||||
2. **Configure NAS connection** ⚠️ **DO THIS NOW**
|
||||
```bash
|
||||
sudo nvim /etc/backup.conf
|
||||
|
||||
# Edit these values:
|
||||
# NAS_HOST="your-nas-hostname"
|
||||
# NAS_USER="your-backup-user"
|
||||
# NAS_PATH="/path/to/backup/dir"
|
||||
```
|
||||
|
||||
3. **Set up SSH key authentication** ⚠️ **REQUIRED**
|
||||
```bash
|
||||
# Generate SSH key if you don't have one
|
||||
ssh-keygen -t ed25519 -C "backup@gentoo-workstation"
|
||||
|
||||
# Copy to NAS
|
||||
ssh-copy-id -p 22 backup-user@nas-hostname
|
||||
```
|
||||
|
||||
4. **Test connection**
|
||||
```bash
|
||||
backup-setup test
|
||||
```
|
||||
|
||||
5. **Test backup (configs - lightweight)**
|
||||
```bash
|
||||
backup-setup backup configs
|
||||
```
|
||||
|
||||
6. **Check backup status**
|
||||
```bash
|
||||
backup-setup status
|
||||
backup-setup list
|
||||
backup-setup logs
|
||||
```
|
||||
|
||||
### Next Steps
|
||||
|
||||
After successful backup test:
|
||||
|
||||
1. **Create ZSH completion** - For backup-setup autocompletion
|
||||
2. **Create network trigger** - Automated backups when NAS detected
|
||||
3. **Implement firewall** - nftables configuration
|
||||
4. **Set up fail2ban** - SSH protection
|
||||
5. **Create documentation** - Complete guides

## Testing Checklist
|
||||
|
||||
### Backup System Testing
|
||||
|
||||
- [ ] Configuration file created (`/etc/backup.conf`)
|
||||

|
||||
- [ ] SSH key authentication set up
|
||||
- [ ] Connection test passes (`backup-setup test`)
|
||||

|
||||
|
||||
### Security Testing (Future)
|
||||

## Notes
|
||||
|
||||
- Backup system is functional and ready for testing
|
||||
- Security hardening will begin after backup system is confirmed working
|
||||
- Network trigger will be implemented using OpenRC service (not systemd)
|
||||
- All scripts are POSIX sh compatible
|
||||
- Follows same pattern as existing scripts (wifi-setup, audio-setup, etc.)
