400955fdb5 In the updated version of the script (V2), we've added a critical feature that checks the available storage on the Home Assistant server. If the available storage falls below 2GB, the script will automatically remove a defined number of days' worth of old backups, ensuring that the system doesn't run out of space. This storage threshold is configurable, and you can adjust the number of days' worth of backups to be retained according to your needs. This feature is designed to help manage storage effectively—because, as we all know, storage isn't infinite! 😄 Additionally, both V1 and V2 of the scripts now include much more detailed and comprehensive README.md files, offering users a clearer understanding of the setup, configuration, and usage. The documentation includes step-by-step instructions, explanations of configurable options, and tips for maintaining a reliable backup routine for your Home Assistant server. 2025-01-05 18:16:51 +00:00

# Home-Assistant-Backup-Script
# Home Assistant Backup Automation Scripts
These scripts automate the backup process for **Home Assistant** servers, enabling you to create, transfer, and manage backups. The backups are securely transferred from the Home Assistant server to your local machine, with options for cleaning up old backups based on configurable retention periods.
## Overview
### Features:
- **Backup Creation**: Automates the process of creating backups on your Home Assistant server.
- **Backup Transfer**: Transfers the generated backups to a local machine for safekeeping.
- **Old Backup Cleanup**: Automatically cleans up old backups on both the Home Assistant server and local machine after a specified retention period.
- **Notification Support** (Optional): Configure **ntfy** or **Discord** notifications to alert you about the backup status (available in the first script version).
### Two Versions of the Script:
1. **Version 1: Simple Backup with Cleanup**
A simpler version that creates a backup, copies it to your local machine, and performs a basic cleanup of old backups locally. No notification system is included in this version.
2. **Version 2: Full Backup and Cleanup with Notifications**
This version includes backup creation, local and remote cleanup of old backups, and optional notifications via **ntfy** and **Discord**. It also checks for available disk space before cleaning up old backups.
## Requirements
Both scripts require the following to function correctly:
- **Bash shell** (on your local machine and Home Assistant server)
- **SSH** access to the Home Assistant server
- **`scp`** and **`ssh`** tools
- **Home Assistant** installed on the server with the `ha` CLI tool
- **Optional**: Access to a notification service (for Version 2)
## Configuration
Before running either script, you need to set up a few configuration parameters. These include SSH credentials, backup destination paths, and notification settings.
- **HA_SSH_KEY**: Path to your private SSH key for accessing the Home Assistant server.
- **HA_SSH_USER**: The SSH username (default is `root`).
- **HA_SSH_HOST**: The IP address or hostname of your Home Assistant server.
- **BACKUP_DEST**: Path to the directory where backups will be saved locally.
- **Retention Settings**: You can configure how long old backups are kept before they are deleted (default is 30 days for local and remote backups).
- **Optional**: Set up **ntfy** or **Discord** notifications to receive alerts when backups are created or when errors occur.
## How to Use
### Step 1: Configure the Script
Open the script file in a text editor and set the following variables:
- **SSH credentials** (`HA_SSH_KEY`, `HA_SSH_USER`, `HA_SSH_HOST`)
- **Backup destination path** (`BACKUP_DEST`)
- **Notification settings** (optional)
### Step 2: Make the Script Executable
After configuring the script, make it executable by running:
```
chmod +x home_assistant_backup.sh
```

# Home Assistant Backup Script
This script automates the process of creating and copying backups from a Home Assistant server to a local machine. It includes functionality for:
- Creating a new backup on the Home Assistant server.
- Copying the backup file to a specified local destination.
- Cleaning up old backups based on a specified retention period.
## Requirements
- Bash shell
- SSH access to your Home Assistant server
- `scp` and `ssh` tools
- Access to a Home Assistant server with the `ha` command line tool installed
## Configuration
Before using the script, you need to configure the following variables:
### Global Settings
- **HA_SSH_KEY**: Path to your SSH private key for accessing the Home Assistant server.
- **HA_SSH_USER**: The SSH username to use for connecting to the Home Assistant server (usually `root`).
- **HA_SSH_HOST**: The IP address or hostname of your Home Assistant server.
- **BACKUP_DEST**: The destination directory on your local machine where the backup file will be stored.
### Backup Retention
- The script will automatically clean up backup files on the local machine that are older than 30 days. You can adjust this retention period by modifying the `-mtime +30` argument in the `find` command to a different number of days.
## Script Flow
1. **Backup Creation**: The script connects to the Home Assistant server via SSH and creates a new backup using the `ha backup new` command. It generates a timestamped name for the backup.
2. **Backup Transfer**: The backup file is copied from the Home Assistant server to your local machine using `scp`.
3. **Local Backup Cleanup**: The script will automatically remove local backups that are older than the configured retention period (default is 30 days).
4. **Completion Message**: A success message is displayed after the backup process is complete.
## Usage
1. **Clone or Download the Script**:
- Clone the repository or download the script file.
2. **Make the Script Executable**:
```
chmod +x home_assistant_backup.sh
```

# Home Assistant Backup Script
This script automates the process of creating, copying, and cleaning up backups for a Home Assistant server. It supports the ability to:
- Create a backup on the Home Assistant server.
- Copy the backup file to a local machine.
- Clean up old backups on both the local machine and Home Assistant server.

- ntfy.sh server (if using ntfy.sh notifications) (https://ntfy.sh/)
## Configuration
Before using the script, you need to set up the following environment variables in the script:
### Global Settings
- **HA_SSH_KEY**: Path to your SSH private key for Home Assistant.
- **HA_SSH_USER**: Username for SSH login (usually `root`).
- **HA_SSH_HOST**: IP address or hostname of your Home Assistant server.
- **HA_SSH_PORT**: SSH port (default is 22).
- **BACKUP_DEST**: Destination directory for storing local backups.
- **BACKUP_FILE_LOCATION**: Location of the backups on the Home Assistant server (default is `/backup`).
- **LOCAL_BACKUP_CLEANUP**: Number of days to keep local backups (default is 90 days).
- **REMOTE_BACKUP_CLEANUP**: Number of days to keep backups on the Home Assistant server (default is 30 days).
- **NTFY_ENABLED**: Set to `true` to enable `ntfy` notifications.
- **NTFY_SERVER**: The FQDN of your `ntfy` server.
- **NTFY_TOPIC**: The topic for your `ntfy` notifications.
- **DISCORD_ENABLED**: Set to `true` to enable Discord notifications.
- **DISCORD_WEBHOOK_URL**: Your Discord webhook URL.
- **STORAGE_THRESHOLD_KB**: The disk space threshold in KB for triggering cleanup (default is 2GB).
### Notifications
- **ntfy**: Notifications are sent via HTTP POST to your `ntfy` server.
- **Discord**: Notifications are sent via a Discord webhook.
Set `NTFY_ENABLED` and `DISCORD_ENABLED` to `true` to enable notifications for respective services. Replace the relevant URLs and topics.
## Script Flow
1. **Backup Creation**: The script first creates a backup on the Home Assistant server.
2. **Disk Space Check**: It checks available disk space on the Home Assistant server. If it is less than the specified threshold, it will clean up old backups on the Home Assistant server.
3. **Backup Transfer**: The backup file is then copied from the Home Assistant server to the local backup destination.
4. **Local Cleanup**: Old backups are removed from the local machine if they exceed the specified retention period.
5. **Notification**: Notifications are sent at each major step (e.g., start of backup, successful backup, cleanup actions) via `ntfy` and Discord if enabled.
6. **Backup File Size and Script Runtime**: The script reports the backup file size and runtime after completing the backup process.
## Usage
1. **Clone or Download the Script**:
- Clone the repository or download the script file.
2. **Make the Script Executable**:
