Duplicity Backblaze B2

Posted : admin On 1/29/2022

Amazon S3 has been around for more than ten years now and I have been happily using it for offsite backups of my servers for a long time.

Backblaze offers B2 cloud storage which is similar to and compatible with Amazon S3.

The first 10 GB of storage is free as is the first 1 GB of daily downloads. For my small server backup requirements this sounds perfect.

My backup tool of choice is duplicity, a command line backup tool that supports encrypted archives and a whole load of different storage services, including S3 and B2. It was a simple matter to create a new bucket on B2 and update my backup script to send the data to Backblaze instead of Amazon.
