4 ways to move files to and from Backblaze B2
Whether you need manual transfers, self-service uploads, email-based collection, or fully automated workflows, Couchdrop provides a secure SFTP gateway into your Backblaze B2 environment.
Direct SFTP/FTP access
Create SFTP user accounts that map directly to Backblaze B2 folders. Partners connect using standard FTP clients like FileZilla or WinSCP to upload and download files. You control permissions down to the folder level, while they use the tools they already know.
Web upload portals
Generate secure, branded upload pages where external users can drag-and-drop files directly into Backblaze B2. No accounts or software needed—just send them a link. Perfect for collecting documents from clients, vendors, or anyone who needs to send you files occasionally.
Email inboxes
Create dedicated email addresses that automatically extract attachments and save them to Backblaze B2. Partners just email files like they always have—Couchdrop handles the rest. Set rules to route files based on sender, subject, or attachment type.
Automated transfers
Set up scheduled or triggered file movements between Backblaze B2 and any SFTP endpoint. Monitor Backblaze B2 folders and automatically send new files to partners, or pull files from external servers into Backblaze B2. Build complex workflows with file processing, routing, and notifications—all without writing code.

Common use cases
From vendor invoices to automated reports, here's how some organizations are using Couchdrop with Backblaze B2.
B2B file exchange
Exchange files with partners, suppliers, and customers using their preferred FTP clients. Give each partner their own SFTP account with access to specific your Backblaze B2 folders. They upload purchase orders, you send back confirmations—all automated and tracked.
