Nefarius.Backblaze.NativeApi

.NET Requirements Nuget Nuget

Small wrapper for Backblaze B2 Native API using Refit.

This project is still evolving, so API-breaking changes might occur each update!

About

A thin .NET wrapper around the Backblaze B2 Native API designed to fit into modern dependency injection setups.

Current features

  • Registration helper AddBackblazeUploader to wire up typed HTTP clients and configuration in DI containers.
  • IBackblazeUploader for uploading files or streams with automatic SHA1 calculation and upload URL negotiation.
  • IBackblazeBucketClient for listing file names and file versions in a bucket.
  • Backed by strongly typed Refit clients for authorization, bucket, and upload endpoints.

Usage examples

Dependency injection registration

using Microsoft.Extensions.DependencyInjection;
using Nefarius.Backblaze.NativeApi;

var builder = Host.CreateApplicationBuilder(args);

builder.Services.AddBackblazeUploader(options =>
{
    options.KeyId = builder.Configuration["Backblaze:KeyId"];
    options.ApplicationKey = builder.Configuration["Backblaze:ApplicationKey"];
    options.BucketId = builder.Configuration["Backblaze:BucketId"];
});

Upload a file

using Nefarius.Backblaze.NativeApi;

public class UploaderService(IBackblazeUploader uploader)
{
    public async Task UploadAsync(CancellationToken cancellationToken)
    {
        await uploader.UploadAsync("/path/to/local/file.zip", "backups/file.zip", cancellationToken);
    }
}

List files in a bucket

using Nefarius.Backblaze.NativeApi;
using Nefarius.Backblaze.NativeApi.WebApi.Models;

public class ListingService(IBackblazeBucketClient client, ILogger<ListingService> logger)
{
    public async Task LogFileNamesAsync(CancellationToken cancellationToken)
    {
        B2ListFileNamesResponse files = await client.ListFileNamesAsync(cancellationToken: cancellationToken);

        foreach (B2StorageFile file in files.Files)
        {
            logger.LogInformation("Found remote file: {FileName}", file.FileName);
        }
    }
}
