## 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
|

## 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.)
