Backblaze B2 encryption software for all your cloud data

Backblaze B2 Cloud Storage works the same way as Amazon S3 or Microsoft Azure - it offers unlimited data storage in the cloud. The Backblaze B2 cloud storage solution is reliable and scalable - developers can work on new apps, corporate workers can store important data, and regular users can keep data of various importance online. For the better Backblaze security we recommend using CloudMounter. This Backblaze B2 client for Mac offers encryption for cloud files, and even if someone somehow obtains the access to your B2 storage account from a different device, they will only see a confusing nonsense.

Mount B2 as drive

Use Backblaze as network drive with CloudMounter. And you actually won't need to synchronize data between computer and cloud, which helps save your valuable hard drive space.

Online files within easy reach

Thanks to mounting B2 cloud storage as a local drive you get to access your cloud files as easily as if they were stored on a local disk.

Why users prefer CloudMounter

Being a "youngster" in the software world, CloudMounter impresses with the set of features it has to offer and with the amount of supported cloud storages and web servers.

Finder Integration

To offer you a great level of convenience, CloudMounter smoothly integrates its features with Finder. You won't even feel the difference between working with local and cloud files.

Top standards of privacy

CloudMounter respects your privacy and never stores your login data. Everything is kept in Mac OS Keychain and is only used to log in to a specific account when you are working with it. Everything is performed through encrypted channels.

Other cloud services

Additionally to what CloudMounter already supports, we are constantly working on new clouds and web servers. This way even if you feel like changing the storage, you won't have to change the cloud manager!

Encrypt other cloud storages and web servers

With CloudMounter it’s also possible to encrypt Dropbox, Google Drive, OneDrive, Amazon S3, OpenStack Swift, pCloud data as well as the files on FTP/SFTP, WebDAV servers.
