Backblaze vs WeTransfer

Backblaze is a publicly traded storage company from San Mateo, California, founded in 2007, that runs its own data centers and sells two products. Computer Backup continuously backs up an entire Mac or Windows PC, including attached external drives, for a flat monthly price with no data cap. B2 Cloud Storage is S3-compatible object storage priced per terabyte, positioned as a much cheaper alternative to Amazon S3, Google Cloud Storage and Azure Blob Storage.

Computer Backup offers version history, restores through the web and the app, and the option to have data shipped on a USB drive. B2 includes free egress up to three times the data stored each month, free transfer through partners such as Cloudflare, object lock for immutable, ransomware-resistant backups, and integrations with tools like Veeam, Synology, QNAP, rclone and media asset managers. The first 10 GB of B2 storage is free, and billing beyond that is simple and predictable.

Backblaze suits individuals and creatives who want set-and-forget workstation backup, and developers or IT teams storing backups, media archives and app uploads cheaply. It is not a sync or collaboration tool like Dropbox, it offers far fewer regions and services than AWS, and very large Computer Backup restores can be slow. Against Wasabi it competes on egress terms and ecosystem, and against IDrive on simplicity. The company is also known for publishing quarterly hard drive reliability statistics from its own fleet.

WeTransfer is a file transfer service founded in Amsterdam in 2009 that became the standard way for creative professionals to send large files. You upload files, enter recipients' email addresses or create a link, and the recipient downloads them without needing an account. The company was acquired by Bending Spoons, the Italian app developer, in 2024.

The free plan lets you send files up to a size limit per transfer with a cap on monthly transfers, and transfers expire after a short period. Paid plans raise the size limit, keep files available longer, and add password protection, custom expiry dates, download tracking, branded backgrounds and pages, and storage for files you want to keep. Teams plans add shared administration and collaboration. Over the years WeTransfer has also added tools for collecting feedback on files, though the core product remains simple, fast transfer.

WeTransfer fits photographers, designers, video editors and agencies that need to deliver large files to clients quickly. It is not a cloud storage or sync service, so ongoing collaboration on shared folders is better in Dropbox, Google Drive or OneDrive. Free limits have tightened since the acquisition, and in 2025 a change to its terms of service raised concerns about AI training on user files, which the company then clarified and rewrote. Smash is a French alternative with no size limit on free transfers, and Filemail is another option for very large files.
