# Backblaze Backup Tool

This is a tool to backup files and directories to Backblaze.

## Prerequisites

- Go 1.16 or higher
- Backblaze account with a bucket created
- Environment variables `BB_ID` and `BB_KEY` set with your Backblaze account ID and application key respectively

## Building the Application

You can build the application using the provided Makefile. 

### On Linux:

```bash
make rebuild
```

### On Windows:

You will need to have make installed. If you don't have it, you can install it through Chocolatey:
```bash
choco install make
```

Then you can run the same command as on Linux:
```bash
make rebuild
```

This will create a binary in the bin directory.


## Running the Application

You can run the application directly from the command line. Here's how to do it:
```bash
./bin/backblaze-backup sync --bucket "your-bucket-name" --dir "/path/to/directory"
```

Or if you want to upload a single file:
```bash
./bin/backblaze-backup sync --bucket "your-bucket-name" --file "/path/to/file"
```

You can also use the **`local_run`** command in the Makefile to run the application with a test directory and bucket:

```bash
make local_run DIR="/home/user/test-upload" BUCKET="my-test-bucket"
```

This will run the application with the directory **/home/user/test-upload** and the bucket **my-test-bucket**.

## Flags

    --bucket: The name of your Backblaze bucket
    --dir: The absolute path of the directory you want to upload to Backblaze
    --file: The absolute path of the file you want to upload to Backblaze

Note: You must select just one option, dir or file.

Please replace `"your-bucket-name"`, `"/path/to/directory"`, and `"/path/to/file"` with your actual bucket name and paths.


## Environment Variables
The application uses the following environment variables:

- **BB_ID:** Your Backblaze account ID
- **BB_KEY:** Your Backblaze application key

You can set these variables in your environment, or you can use a **.env** file in the root directory of the project. If the **BACKBLAZE_ENV** environment variable is set to dev, the application will load the **.env** file.

## Syncing with Backblaze
The application uses the Sync method of the BackBlaze service to sync files or directories to Backblaze. If there's an error during the sync, the application will log the error and exit.

```bash
./bin/backblaze-backup sync
```


## Checking for Duplicate Versions
The application can also check for duplicate versions of files in your Backblaze buckets. To do this, run the following command:

```bash
./bin/backblaze-backup versions
```
If there are any duplicate versions, the application will log them and exit.

## Cleaning Up Duplicate Versions
The application can also clean up duplicate versions of files in your Backblaze buckets. To do this, run the following command:

```bash
./bin/backblaze-backup cleanup
```
If there are any errors during the cleanup, the application will log them and exit.
