# Backing Things Up
|
||
|
||
> [!NOTE]
|
||
> To back up 99% of your configuration, back up at least the `/data/config` folder.
|
||
> Database definitions can change between releases, so the safest method is to restore backups using the **same app version** they were taken from, then upgrade incrementally.

|
||
## What to Back Up
|
||
|
||
There are four key artifacts you can use to back up your NetAlertX configuration:
|
||
|
||
| File | Description | Limitations |
|
||
| ------------------------ | ----------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||
| `/db/app.db` | The application database | Might be in an uncommitted state or corrupted |
|
||
| `/config/app.conf` | Configuration file | Can be overridden using the [`APP_CONF_OVERRIDE`](https://github.com/jokob-sk/NetAlertX/tree/main/dockerfiles#docker-environment-variables) variable |
|
||
| `/config/devices.csv` | CSV file containing device data | Does not include historical data |
|
||
| `/config/workflows.json` | JSON file containing your workflows | N/A |
|
||
|
||
---
|
||
|
||
## Where the Data Lives
|
||
|
||
Understanding where your data is stored helps you plan your backup strategy.
|
||
|
||
### Core Configuration
|
||
|
||
Stored in `/data/config/app.conf`.
|
||
This includes settings for:
|
||
|
||
* Notifications
|
||
* Scanning
|
||
* Scheduled maintenance
|
||
* UI preferences
|
||
|
||
(See [Settings System](./SETTINGS_SYSTEM.md) for details.)
|
||
|
||
### Device Data
|
||
|
||
Stored in `/data/config/devices_<timestamp>.csv` or `/data/config/devices.csv`, created by the [CSV Backup `CSVBCKP` Plugin](https://github.com/jokob-sk/NetAlertX/tree/main/front/plugins/csv_backup).
|
||
Contains:
|
||
|
||
* Device names, icons, and categories
|
||
* Network configuration
|
||
* Custom properties
|
||
|
||
### Historical Data
|
||
|
||
Stored in `/data/db/app.db` (see [Database Overview](./DATABASE.md)).
|
||
Contains:
|
||
|
||
* Plugin data and historical entries
|
||
* Event and notification history
|
||
* Device presence history
|
||
|

||
## Backup Strategies
|
||
|
||
The safest approach is to back up **both** the `/db` and `/config` folders regularly. Tools like [Kopia](https://github.com/kopia/kopia) make this simple and efficient.
|
||
|
||
If you can only keep a few files, prioritize:
|
||
|
||
1. The latest `devices_<timestamp>.csv` or `devices.csv`
|
||
2. `app.conf`
|
||
3. `workflows.json`
|
||
|
||
You can also download the `app.conf` and `devices.csv` files from the **Maintenance** section:
|
||
|
||
|
||

|
||
|
||
## Scenario 1: Full Backup and Restore
|
||
|
||
**Goal:** Full recovery of your configuration and data.
|
||
|
||
### 💾 What to Back Up
|
||
|
||
* `/data/db/app.db` (uncorrupted)
|
||
* `/data/config/app.conf`
|
||
* `/data/config/workflows.json`
|
||
|
||
### 📥 How to Restore
|
||
|
||
Map these files into your container as described in the [Setup documentation](https://github.com/jokob-sk/NetAlertX/blob/main/dockerfiles/README.md#docker-paths).
|
||
|
||
---
|
||
|
||
## Scenario 2: Corrupted Database
|
||
|
||
**Goal:** Recover configuration and device data when the database is lost or corrupted.
|
||
|
||
### 💾 What to Back Up
|
||
|
||
* `/data/config/app.conf`
|
||
* `/data/config/workflows.json`
|
||
* `/data/config/devices_<timestamp>.csv` (rename to `devices.csv` during restore)
|
||
|
||
### 📥 How to Restore
|
||
|
||
1. Copy `app.conf` and `workflows.json` into `/data/config/`
|
||
2. Rename and place `devices_<timestamp>.csv` → `/data/config/devices.csv`
|
||
3. Restore via the **Maintenance** section under *Devices → Bulk Editing*
|
||
|
||
This recovers nearly all configuration, workflows, and device metadata.

||
## Docker-Based Backup and Restore
|
||
|
||
For users running NetAlertX via Docker, you can back up or restore directly from your host system — a convenient and scriptable option.
|
||
|
||
### Full Backup (File-Level)
|
||
|
||
1. **Stop the container:**
|
||
|
||
```bash
|
||
docker stop netalertx
|
||
```
|
||
|
||
2. **Create a compressed archive** of your configuration and database volumes:
|
||
|
||
```bash
|
||
docker run --rm -v local_path/config:/config -v local_path/db:/db alpine tar -cz /config /db > netalertx-backup.tar.gz
|
||
```
|
||
|
||
3. **Restart the container:**
|
||
|
||
```bash
|
||
docker start netalertx
|
||
```
|
||
|
||
### Restore from Backup
|
||
|
||
1. **Stop the container:**
|
||
|
||
```bash
|
||
docker stop netalertx
|
||
```
|
||
|
||
2. **Restore from your backup file:**
|
||
|
||
```bash
|
||
docker run --rm -i -v local_path/config:/config -v local_path/db:/db alpine tar -C / -xz < netalertx-backup.tar.gz
|
||
```
|
||
|
||
3. **Restart the container:**
|
||
|
||
```bash
|
||
docker start netalertx
|
||
```
|
||
|
||
> This approach uses a temporary, minimal `alpine` container to access Docker-managed volumes. The `tar` command creates or extracts an archive directly from your host’s filesystem, making it fast, clean, and reliable for both automation and manual recovery.

||
## Summary
|
||
|
||
* Back up `/data/config` for configuration and devices; `/data/db` for history
|
||
* Keep regular backups, especially before upgrades
|
||
* For Docker setups, use the lightweight `alpine`-based backup method for consistency and portability
