+# NAS Mount Setup Guide for Fedora 42
+
+## Quick Setup Instructions
+
+Your NAS IP: `192.168.68.51`
+Mount Point: `/mnt/share/media`
+
+### Prerequisites (Already Installed)
+- `cifs-utils` - for SMB/CIFS mounting
+- `nfs-utils` - for NFS mounting
+
+### Option 1: Automated Setup (Recommended)
+
+Run the interactive setup script:
+```bash
+./setup-nas-mount.sh
+```
+
+This script will:
+- Test both SMB and NFS connectivity
+- Guide you through the setup process
+- Create persistent mount configuration
+- Set up systemd mount units for reliable boot mounting
+
+### Option 2: Manual SMB/CIFS Setup
+
+1. **Test SMB shares first:**
+   ```bash
+   # List available shares (you'll need NAS credentials)
+   smbclient -L 192.168.68.51 -U your_username
+   ```
+
+2. **Create credentials file (if using authentication):**
+   ```bash
+   sudo tee /etc/nas-credentials << EOF
+   username=your_nas_username
+   password=your_nas_password
+   domain=WORKGROUP
+   EOF
+   sudo chmod 600 /etc/nas-credentials
+   ```
+
+3. **Test mount:**
+   ```bash
+   # With credentials
+   sudo mount -t cifs //192.168.68.51/share_name /mnt/share/media -o credentials=/etc/nas-credentials,uid=$(id -u),gid=$(id -g),iocharset=utf8
+
+   # Or for guest access
+   sudo mount -t cifs //192.168.68.51/share_name /mnt/share/media -o guest,uid=$(id -u),gid=$(id -g),iocharset=utf8
+   ```
+
+4. **Add to /etc/fstab for persistence:**
+   ```bash
+   # Backup fstab first
+   sudo cp /etc/fstab /etc/fstab.backup
+
+   # Add entry (with credentials)
+   echo "//192.168.68.51/share_name /mnt/share/media cifs credentials=/etc/nas-credentials,uid=$(id -u),gid=$(id -g),iocharset=utf8,noauto,user 0 0" | sudo tee -a /etc/fstab
+
+   # Or for guest access
+   echo "//192.168.68.51/share_name /mnt/share/media cifs guest,uid=$(id -u),gid=$(id -g),iocharset=utf8,noauto,user 0 0" | sudo tee -a /etc/fstab
+   ```
+
+### Option 3: Manual NFS Setup
+
+1. **Check available NFS exports:**
+   ```bash
+   showmount -e 192.168.68.51
+   ```
+
+2. **Test mount:**
+   ```bash
+   sudo mount -t nfs 192.168.68.51:/path/to/export /mnt/share/media -o rw,hard,intr
+   ```
+
+3. **Add to /etc/fstab:**
+   ```bash
+   echo "192.168.68.51:/path/to/export /mnt/share/media nfs rw,hard,intr,rsize=8192,wsize=8192,timeo=14,noauto,user 0 0" | sudo tee -a /etc/fstab
+   ```
+
+### Systemd Mount Unit (For Reliable Boot Mounting)
+
+Create `/etc/systemd/system/mnt-share-media.mount`:
+
+```ini
+[Unit]
+Description=Mount NAS Media Share
+After=network-online.target
+Wants=network-online.target
+
+[Mount]
+What=//192.168.68.51/share_name
+Where=/mnt/share/media
+Type=cifs
+Options=credentials=/etc/nas-credentials,uid=1000,gid=1000,iocharset=utf8
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Enable it:
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable mnt-share-media.mount
+sudo systemctl start mnt-share-media.mount
+```
+
+### Common Commands
+
+- **Mount manually:** `sudo mount /mnt/share/media`
+- **Unmount:** `sudo umount /mnt/share/media`
+- **Check mount status:** `df -h /mnt/share/media`
+- **Test systemd mount:** `sudo systemctl start mnt-share-media.mount`
+
+### Troubleshooting
+
+1. **Check connectivity:**
+   ```bash
+   ping 192.168.68.51
+   ```
+
+2. **Test SMB connection:**
+   ```bash
+   nc -zv 192.168.68.51 445
+   ```
+
+3. **Test NFS connection:**
+   ```bash
+   nc -zv 192.168.68.51 2049
+   ```
+
+4. **Check mount logs:**
+   ```bash
+   journalctl -u mnt-share-media.mount
+   ```
+
+5. **Verify fstab syntax:**
+   ```bash
+   sudo mount -a
+   ```
+
+### Security Notes
+
+- Credentials file should have 600 permissions (readable only by root)
+- Consider using NFS over SMB for better performance on Linux
+- Use `noauto` in fstab to prevent boot delays if NAS is unavailable
+- The `user` option allows regular users to mount/unmount
+
+### Integration with Your Backup Scripts
+
+Your `backup-media.sh` script already references `/mnt/share/media/backups`, so once the NAS is mounted, your backups will automatically work with the NAS storage.
+
+Make sure your backup script has proper error handling for when the NAS is not mounted:
+
+```bash
+# Add this check to your backup scripts
+if ! mountpoint -q /mnt/share/media; then
+    log_error "NAS not mounted at /mnt/share/media"
+    exit 1
+fi
+```
