Backblaze Backup Tool
This is a tool to backup files and directories to Backblaze.
- Go 1.16 or higher
- Backblaze account with a bucket created
- Environment variables
BB_KEYset with your Backblaze account ID and application key respectively
Building the Application
You can build the application using the provided Makefile.
You will need to have make installed. If you don't have it, you can install it through Chocolatey:
choco install make
Then you can run the same command as on Linux:
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:
./bin/backblaze-backup sync --bucket "your-bucket-name" --dir "/path/to/directory"
Or if you want to upload a single file:
./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:
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.
--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.
"/path/to/file" with your actual bucket name and paths.
The application uses the following environment variables:
- BB_ID: Your Backblaze account ID
- BB_KEY: Your Backblaze application key
- LOG_LEVEL: Sets the log level (DEBUG, INFO, WARN, ERROR). Default is INFO.
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.
The application supports configurable logging levels. Set the LOG_LEVEL environment variable to one of the following values:
- DEBUG: Detailed debug information
- INFO: Informational messages
- WARN: Warnings
- ERROR: Errors only
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.
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:
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:
If there are any errors during the cleanup, the application will log them and exit.
Check discrepancy between local backup and B2
The application can also check that all local files has been backed up into B2 cloud. To do this, run the following command:
./bin/backblaze-backup check --dir "/var/tmp/test-upload" --bucket "b2-bucket"
If there are any errors during the check, the application will log them and exit.
