Nautical itself does not have the ability to map network shares. However, it can use a network share for either the source or destination.

Commonly, we run containers on our host machine, then use an NFS share as the backup destination location. This page will give a brief overview of how to do that.

Connect to an NFS Share On Container Host (Linux)

Create the NFS destination directories.
```
# Create mount point (1)
mkdir -p /mnt/nfs/docker_backups
```
1. The destination directories must exist before a mount can be created

Setup NFS mount points:

nano /etc/fstab

This will open a file, and here you can insert your NFS configuration:

# | ------------- Source -------------- | ---- Destination ---- | -------- Options ---------- |
192.168.1.10:/mnt/backups/docker_volumes /mnt/nfs/docker_backups nfs _netdev,auto,rw,async 0 0

Tip: 192.168.1.10 is just an example IP address

Apply and mount the NFS shares
```
mount -a
```
!!! success "A successful mount -a will return nothing in the console"

Verify read and write access

cd /mnt/nfs/docker_backups
touch test.txt && rm test.txt

Add Nautical Backup

The above example created a local directory of /mnt/nfs/docker_backups which is an NFS share pointing to 192.168.1.10:/mnt/backups/docker_volumes.

Here is how we can use this new mount withing Nautical: === "Docker Compose" ```yaml hl_lines="9" ------8<------ "docker-compose-example.yml:0:9" - /mnt/nfs/docker_backups:/app/destination #(3) <-- NFS Share

```

------8<------ "docker-example-tooltips.md"

=== "Docker Run" bash hl_lines="5" ------8<------ "docker-run-example.sh:0:5" -v /mnt/nfs/docker_backups:/app/destination \ #(2)! ------8<------ "docker-run-example.sh:10:"

------8<------ "docker-example-tooltips.md"
