-## Supported Engines
-
-This image is developed and tested against the Docker CE engine and Kubernetes exclusively.
-While it may work against different implementations, there are no guarantees about support for non-Docker engines.
-
 ## References
 
-We decided to publish this image as a simpler and more lightweight alternative because of the following requirements:
+We created this image as a simpler and more lightweight alternative to existing solutions. Here’s why:
 
-- The original image is based on `ubuntu` and requires additional tools, making it heavy.
-- This image is written in Go.
-- `arm64` and `arm/v7` architectures are supported.
-- Docker in Swarm mode is supported.
-- Kubernetes is supported.
+- **Lightweight:** Written in Go, the image is optimized for performance and minimal resource usage.
+- **Multi-Architecture Support:** Supports `arm64` and `arm/v7` architectures.
+- **Docker Swarm Support:** Fully compatible with Docker in Swarm mode.
+- **Kubernetes Support:** Designed to work seamlessly with Kubernetes.

+# Backup to Azure Blob Storage
+
+To store your backups on Azure Blob Storage, you can configure the backup process to use the `--storage azure` option.
+
+This section explains how to set up and configure Azure Blob-based backups.
+
+---
+
+## Configuration Steps
+
+1. **Specify the Storage Type**  
+   Add the `--storage azure` flag to your backup command.
+
+2. **Set the Blob Path**  
+   Optionally, specify a custom folder within your Azure Blob container where backups will be stored using the `--path` flag.  
+   Example: `--path my-custom-path`.
+
+3. **Required Environment Variables**  
+   The following environment variables are mandatory for Azure Blob-based backups:
+
+    - `AZURE_STORAGE_CONTAINER_NAME`: The name of the Azure Blob container where backups will be stored.
+    - `AZURE_STORAGE_ACCOUNT_NAME`: The name of your Azure Storage account.
+    - `AZURE_STORAGE_ACCOUNT_KEY`: The access key for your Azure Storage account.
+
+---
+
+## Example Configuration
+
+Below is an example `docker-compose.yml` configuration for backing up to Azure Blob Storage:
+
+```yaml
+services:
+  mysql-bkup:
+    # In production, lock your image tag to a specific release version
+    # instead of using `latest`. Check https://github.com/jkaninda/mysqlbkup/releases
+    # for available releases.
+    image: jkaninda/mysql-bkup
+    container_name: mysql-bkup
+    command: backup --storage azure -d database --path my-custom-path
+    environment:
+      - DB_PORT=3306
+      - DB_HOST=mysql
+      - DB_NAME=database
+      - DB_USERNAME=username
+      - DB_PASSWORD=password
+      ## Azure Blob Configuration
+      - AZURE_STORAGE_CONTAINER_NAME=backup-container
+      - AZURE_STORAGE_ACCOUNT_NAME=account-name
+      - AZURE_STORAGE_ACCOUNT_KEY=Ppby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==
+
+    # Ensure the mysql-bkup container is connected to the same network as your database
+    networks:
+      - web
+
+networks:
+  web:
+```
+
+---
+
+## Key Notes
+
+- **Custom Path**: Use the `--path` flag to specify a folder within your Azure Blob container for organizing backups.
+- **Security**: Ensure your `AZURE_STORAGE_ACCOUNT_KEY` is kept secure and not exposed in public repositories.
+- **Compatibility**: This configuration works with Azure Blob Storage and other compatible storage solutions.

+# Backup to FTP Remote Server
+
+To store your backups on an FTP remote server, you can configure the backup process to use the `--storage ftp` option. 
+
+This section explains how to set up and configure FTP-based backups.
+
+---
+
+## Configuration Steps
+
+1. **Specify the Storage Type**  
+   Add the `--storage ftp` flag to your backup command.
+
+2. **Set the Remote Path**  
+   Define the full remote path where backups will be stored using the `--path` flag or the `REMOTE_PATH` environment variable.  
+   Example: `--path /home/jkaninda/backups`.
+
+3. **Required Environment Variables**  
+   The following environment variables are mandatory for FTP-based backups:
+
+    - `FTP_HOST`: The hostname or IP address of the FTP server.
+    - `FTP_PORT`: The FTP port (default is `21`).
+    - `FTP_USER`: The username for FTP authentication.
+    - `FTP_PASSWORD`: The password for FTP authentication.
+    - `REMOTE_PATH`: The directory on the FTP server where backups will be stored.
+
+---
+
+## Example Configuration
+
+Below is an example `docker-compose.yml` configuration for backing up to an FTP remote server:
+
+```yaml
+services:
+  mysql-bkup:
+    # In production, lock your image tag to a specific release version
+    # instead of using `latest`. Check https://github.com/jkaninda/mysql-bkup/releases
+    # for available releases.

+      - DB_HOST=mysql
+      - DB_NAME=database
+      - DB_USERNAME=username

+    networks:
+      - web
+
+networks:
+  web:
+```
+
+---
+
+## Key Notes
+
+- **Security**: FTP transmits data, including passwords, in plaintext. For better security, consider using SFTP (SSH File Transfer Protocol) or FTPS (FTP Secure) if supported by your server.
+- **Remote Path**: Ensure the `REMOTE_PATH` directory exists on the FTP server and is writable by the specified `FTP_USER`.

+  web:
+```
+
+---
+
+## Key Notes
+
+- **Cron Expression**: Use the `--cron-expression` flag or `BACKUP_CRON_EXPRESSION` environment variable to define the backup schedule. For example, `0 1 * * *` runs the backup daily at 1:00 AM.
+- **Backup Retention**: Optionally, use the `BACKUP_RETENTION_DAYS` environment variable to automatically delete backups older than a specified number of days.
+- **S3 Alternatives**: If using an S3 alternative like Minio, set `AWS_DISABLE_SSL="true"` and `AWS_FORCE_PATH_STYLE="true"` as needed.

-# Backup to SSH remote server
+# Backup to SFTP or SSH Remote Server
 
+To store your backups on an `SFTP` or `SSH` remote server instead of the default storage, you can configure the backup process to use the `--storage ssh` or `--storage remote` option.
+This section explains how to set up and configure SSH-based backups.
 
-As described for s3 backup section, to change the storage of your backup and use SSH Remote server as storage. You need to add `--storage ssh` or `--storage remote`.
-You need to add the full remote path by adding `--path /home/jkaninda/backups` flag or using `SSH_REMOTE_PATH` environment variable.
+---
+
+## Configuration Steps
+
+1. **Specify the Storage Type**  
+   Add the `--storage ssh` or `--storage remote` flag to your backup command.
+
+2. **Set the Remote Path**  
+   Define the full remote path where backups will be stored using the `--path` flag or the `REMOTE_PATH` environment variable.  
+   Example: `--path /home/jkaninda/backups`.
+
+3. **Required Environment Variables**  
+   The following environment variables are mandatory for SSH-based backups:
+
+    - `SSH_HOST`: The hostname or IP address of the remote server.
+    - `SSH_USER`: The username for SSH authentication.
+    - `REMOTE_PATH`: The directory on the remote server where backups will be stored.
+    - `SSH_IDENTIFY_FILE`: The path to the private key file for SSH authentication.
+    - `SSH_PORT`: The SSH port (default is `22`).
+    - `SSH_PASSWORD`: (Optional) Use this only if you are not using a private key for authentication.
 
    {: .note }
-These environment variables are required for SSH backup `SSH_HOST_NAME`, `SSH_USER`, `SSH_REMOTE_PATH`, `SSH_IDENTIFY_FILE`, `SSH_PORT` or `SSH_PASSWORD` if you dont use a private key to access to your server.
-Accessing the remote server using password is not recommended, use private key instead.
+   **Security Recommendation**: Using a private key (`SSH_IDENTIFY_FILE`) is strongly recommended over password-based authentication (`SSH_PASSWORD`) for better security.

-## Deploy on Kubernetes
+---
 
-For Kubernetes, you don't need to run it in scheduled mode.
-You can deploy it as CronJob.
+## Recurring Backups to SSH Remote Server
 
-Simple Kubernetes CronJob usage:
+To schedule recurring backups, you can use the `--cron-expression` flag or the `BACKUP_CRON_EXPRESSION` environment variable. 
+This allows you to define a cron schedule for automated backups.
+
+### Example: Recurring Backup Configuration

+## Key Notes
+
+- **Cron Expression**: Use the `--cron-expression` flag or `BACKUP_CRON_EXPRESSION` environment variable to define the backup schedule. For example, `0 1 * * *` runs the backup daily at 1:00 AM.
+- **Backup Retention**: Optionally, use the `BACKUP_RETENTION_DAYS` environment variable to automatically delete backups older than a specified number of days.
+- **Security**: Always prefer private key authentication (`SSH_IDENTIFY_FILE`) over password-based authentication (`SSH_PASSWORD`) for enhanced security.

-# Backup database
+# Backup Database
 
-To backup the database, you need to add `backup` command.
+To back up your database, use the `backup` command.
+
+This section explains how to configure and run backups, including recurring backups, using Docker or Kubernetes.
+
+---
+
+## Default Configuration
+
+- **Storage**: By default, backups are stored locally in the `/backup` directory.
+- **Compression**: Backups are compressed using `gzip` by default. Use the `--disable-compression` flag to disable compression.
+- **Security**: It is recommended to create a dedicated user with read-only access for backup tasks.
 
 {: .note }
-The default storage is local storage mounted to __/backup__. The backup is compressed by default using gzip. The flag __`disable-compression`__ can be used when you need to disable backup compression.
+The backup process supports recurring backups on Docker or Docker Swarm. On Kubernetes, it can be deployed as a CronJob.
 
-{: .warning }
-Creating a user for backup tasks who has read-only access is recommended!
+---
 
-The backup process can be run in scheduled mode for the recurring backups.
-It handles __recurring__ backups of mysql database on Docker and can be deployed as __CronJob on Kubernetes__ using local, AWS S3 or SSH compatible storage.

+            value: "3306"
+          - name: DB_NAME
+            value: "dbname"
+          - name: DB_USERNAME
+            value: "username"
+          - name: DB_PASSWORD
+            value: "password"
+          ## Target Database
+          - name: TARGET_DB_HOST
+            value: "target-postgres"
+          - name: TARGET_DB_PORT

+## Key Notes
+
+- **Security**: Always use Kubernetes Secrets for sensitive data like passwords and access keys.
+- **Resource Limits**: Adjust resource limits (`memory` and `cpu`) based on your workload requirements.
+- **Cron Schedule**: Use standard cron expressions for scheduling recurring backups.
+- **Rootless Deployment**: The image supports running in rootless environments, making it suitable for platforms like OpenShift.

-# Migrate database
+# Migrate Database
 
-To migrate the database, you need to add `migrate` command.
+To migrate a MySQL database from a source to a target database, you can use the `migrate` command. This feature simplifies the process by combining the backup and restore operations into a single step.
 
 {: .note }
-The Mysql backup has another great feature: migrating your database from a source database to a target.
-
-As you know, to restore a database from a source to a target database, you need 2 operations: which is to start by backing up the source database and then restoring the source backed database to the target database.
-Instead of proceeding like that, you can use the integrated feature `(migrate)`, which will help you migrate your database by doing only one operation.
+The `migrate` command eliminates the need for separate backup and restore operations. It directly transfers data from the source database to the target database.
 
 {: .warning }
-The `migrate` operation is irreversible, please backup your target database before this action.
+The `migrate` operation is **irreversible**. Always back up your target database before performing this action.
 
-### Docker compose
-```yml

+
+## Configuration Steps
+
+1. **Source Database**: Provide connection details for the source database.
+2. **Target Database**: Provide connection details for the target database.
+3. **Run the Migration**: Use the `migrate` command to initiate the migration.

+
+# Multiple Backup Schedules
+
+This tool supports running multiple database backup schedules within the same container.
+You can configure these schedules with different settings using a **configuration file**. This flexibility allows you to manage backups for multiple databases efficiently.
+
+---
+
+## Configuration File Setup
+
+The configuration file can be mounted into the container at `/config/config.yaml`, `/config/config.yml`, or specified via the `BACKUP_CONFIG_FILE` environment variable.
+
+### Key Features:
+- **Global Environment Variables**: Use these for databases that share the same configuration.
+- **Database-Specific Overrides**: Override global settings for individual databases by specifying them in the configuration file or using the database name as a suffix in the variable name (e.g., `DB_HOST_DATABASE1`).
+- **Global Cron Expression**: Define a global `cronExpression` in the configuration file to schedule backups for all databases. If omitted, backups will run immediately.
+- **Configuration File Path**: Specify the configuration file path using:
+    - The `BACKUP_CONFIG_FILE` environment variable.
+    - The `--config` or `-c` flag for the backup command.
+
+---
+
+## Configuration File Example
+
+Below is an example configuration file (`config.yaml`) that defines multiple databases and their respective backup settings:
+
+```yaml
+# Optional: Define a global cron expression for scheduled backups.
+# Example: "@every 20m" (runs every 20 minutes). If omitted, backups run immediately.
+cronExpression: ""
+
+databases:
+  - host: mysql1       # Optional: Overrides DB_HOST or uses DB_HOST_DATABASE1.

-## Quickstart
+## Available Image Registries
 
-### Simple backup using Docker CLI
+The Docker image is published to both **Docker Hub** and the **GitHub Container Registry**. You can use either of the following:
 
-To run a one time backup, bind your local volume to `/backup` in the container and run the `backup` command:
-
-```shell
- docker run --rm --network your_network_name \
- -v $PWD/backup:/backup/ \
- -e "DB_HOST=dbhost" \
- -e "DB_USERNAME=username" \
- -e "DB_PASSWORD=password" \
- jkaninda/mysql-bkup backup -d database_name
-```
-
-Alternatively, pass a `--env-file` in order to use a full config as described below.
-
-```yaml
- docker run --rm --network your_network_name \
- --env-file your-env-file \
- -v $PWD/backup:/backup/ \
- jkaninda/mysql-bkup backup -d database_name
-```

+While the documentation references Docker Hub, all examples work seamlessly with `ghcr.io`.
 
-## Supported Engines
-
-This image is developed and tested against the Docker CE engine and Kubernetes exclusively.
-While it may work against different implementations, there are no guarantees about support for non-Docker engines.

 ## References
 
-We decided to publish this image as a simpler and more lightweight alternative because of the following requirements:
+We created this image as a simpler and more lightweight alternative to existing solutions. Here’s why:
 
-- The original image is based on `ubuntu` and requires additional tools, making it heavy.
-- This image is written in Go.
-- `arm64` and `arm/v7` architectures are supported.
-- Docker in Swarm mode is supported.
-- Kubernetes is supported.
+- **Lightweight:** Written in Go, the image is optimized for performance and minimal resource usage.
+- **Multi-Architecture Support:** Supports `arm64` and `arm/v7` architectures.
+- **Docker Swarm Support:** Fully compatible with Docker in Swarm mode.

+# Quickstart
+
+This guide provides quick examples for running backups using Docker CLI, Docker Compose, and Kubernetes.
+
+---
+
+## Simple Backup Using Docker CLI
+
+To run a one-time backup, bind your local volume to `/backup` in the container and execute the `backup` command:
+
+```bash
+docker run --rm --network your_network_name \
+  -v $PWD/backup:/backup/ \
+  -e "DB_HOST=dbhost" \
+  -e "DB_USERNAME=username" \
+  -e "DB_PASSWORD=password" \
+  jkaninda/mysql-bkup backup -d database_name
+```
+
+### Using an Environment File
+
+Alternatively, you can use an `--env-file` to pass a full configuration:
+
+```bash
+docker run --rm --network your_network_name \
+  --env-file your-env-file \
+  -v $PWD/backup:/backup/ \
+  jkaninda/mysql-bkup backup -d database_name
+```
+
+---
+
+## Simple Backup Using Docker Compose
+
+Below is an example `docker-compose.yml` configuration for running a backup:
+
+```yaml
+services:
+  mysql-bkup:
+    # In production, lock the image tag to a specific release version.
+    # Check https://github.com/jkaninda/mysql-bkup/releases for available releases.
+    image: jkaninda/mysql-bkup
+    container_name: mysql-bkup
+    command: backup
+    volumes:
+      - ./backup:/backup
+    environment:
+      - DB_PORT=3306
+      - DB_HOST=mysql
+      - DB_NAME=foo
+      - DB_USERNAME=bar
+      - DB_PASSWORD=password
+      - TZ=Europe/Paris
+    # Ensure the mysql-bkup container is connected to the same network as your database.
+    networks:
+      - web
+
+networks:
+  web:
+```
+
+---
+
+## Recurring Backup with Docker
+
+To schedule recurring backups, use the `--cron-expression` flag:
+
+```bash
+docker run --rm --network network_name \
+  -v $PWD/backup:/backup/ \
+  -e "DB_HOST=hostname" \
+  -e "DB_USERNAME=user" \
+  -e "DB_PASSWORD=password" \
+  jkaninda/mysql-bkup backup -d dbName --cron-expression "@every 15m"
+```
+
+For predefined schedules, refer to the [documentation](https://jkaninda.github.io/mysql-bkup/reference/#predefined-schedules).
+
+---
+
+## Backup Using Kubernetes
+
+Below is an example Kubernetes `Job` configuration for running a backup:
+
+```yaml
+apiVersion: batch/v1
+kind: Job
+metadata:
+  name: backup-job
+spec:
+  ttlSecondsAfterFinished: 100
+  template:
+    spec:
+      containers:
+        - name: mysql-bkup
+          # In production, lock the image tag to a specific release version.
+          # Check https://github.com/jkaninda/mysql-bkup/releases for available releases.
+          image: jkaninda/mysql-bkup
+          command:
+            - /bin/sh
+            - -c
+            - backup -d dbname
+          resources:
+            limits:
+              memory: "128Mi"
+              cpu: "500m"
+          env:
+            - name: DB_HOST
+              value: "mysql"
+            - name: DB_USERNAME
+              value: "postgres"
+            - name: DB_PASSWORD
+              value: "password"
+          volumeMounts:
+            - mountPath: /backup
+              name: backup
+      volumes:
+        - name: backup
+          hostPath:
+            path: /home/toto/backup  # Directory location on the host
+            type: Directory  # Optional field
+      restartPolicy: Never
+```
+
+---
+
+## Key Notes
+
+- **Volume Binding**: Ensure the `/backup` directory is mounted to persist backup files.
+- **Environment Variables**: Use environment variables or an `--env-file` to pass database credentials and other configurations.
+- **Cron Expressions**: Use standard cron expressions or predefined schedules for recurring backups.
+- **Kubernetes Jobs**: Use Kubernetes `Job` or `CronJob` for running backups in a Kubernetes cluster.

-## Run in Scheduled mode
 
-This image can be run as CronJob in Kubernetes for a regular backup which makes deployment on Kubernetes easy as Kubernetes has CronJob resources.
-For Docker, you need to run it in scheduled mode by adding `--mode scheduled` flag and specify the periodical backup time by adding `--period "0 1 * * *"` flag.
+## Scheduled Backups
 
-## Syntax of crontab (field description)
+### Running in Scheduled Mode
 
-The syntax is:
+- **Docker**: Use the `--cron-expression` flag or the `BACKUP_CRON_EXPRESSION` environment variable to schedule backups.
+- **Kubernetes**: Use a `CronJob` resource for scheduled backups.
 
-- 1: Minute (0-59)
-- 2: Hours (0-23)
-- 3: Day (0-31)
-- 4: Month (0-12 [12 == December])
-- 5: Day of the week(0-7 [7 or 0 == sunday])
+### Cron Syntax
 
-Easy to remember format:
+The cron syntax consists of five fields:
 
 ```conf
-* * * * * command to be executed
+* * * * * command
 ```
 
+| Field         | Description                  | Values         |
+|---------------|------------------------------|----------------|
+| Minute        | Minute of the hour           | `0-59`         |
+| Hour          | Hour of the day              | `0-23`         |
+| Day of Month  | Day of the month             | `1-31`         |
+| Month         | Month of the year            | `1-12`         |
+| Day of Week   | Day of the week (0 = Sunday) | `0-7`          |
+
+#### Examples
+
+- **Every 30 minutes**: `*/30 * * * *`
+- **Every hour at minute 0**: `0 * * * *`
+- **Every day at 1:00 AM**: `0 1 * * *`
+
+### Predefined Schedules
+
+| Entry                      | Description                                | Equivalent To |
+|----------------------------|--------------------------------------------|---------------|
+| `@yearly` (or `@annually`) | Run once a year, midnight, Jan. 1st        | `0 0 1 1 *`   |
+| `@monthly`                 | Run once a month, midnight, first of month | `0 0 1 * *`   |
+| `@weekly`                  | Run once a week, midnight between Sat/Sun  | `0 0 * * 0`   |
+| `@daily` (or `@midnight`)  | Run once a day, midnight                   | `0 0 * * *`   |
+| `@hourly`                  | Run once an hour, beginning of hour        | `0 * * * *`   |
+
+### Intervals
+
+You can also schedule backups at fixed intervals using the format:
+
 ```conf
-- - - - -
-| | | | |
-| | | | ----- Day of week (0 - 7) (Sunday=0 or 7)
-| | | ------- Month (1 - 12)
-| | --------- Day of month (1 - 31)
-| ----------- Hour (0 - 23)
-------------- Minute (0 - 59)
+@every <duration>
 ```
 
-> At every 30th minute
-
-```conf
-*/30 * * * *
-```
-> “At minute 0.” every hour
-```conf
-0 * * * *
-```
-
-> “At 01:00.” every day
-
-```conf
-0 1 * * *
-```
+- Example: `@every 1h30m10s` runs the backup every 1 hour, 30 minutes, and 10 seconds.
