The first step will be to initialize the duplicacy backups at the directory to be backed up ( repository in duplicacy terminology). (Your results will reflect the amount of data contained under your current directory, which is likely to be different than this sample amount.) Setup local storage and repository Let’s see how much data is to be backed up: data]# du -s -h Identify the directory to be backed up: ~]# cd data]# pwd The current download costs are $0.01/GB past 1 GB per day, so the download caps may also need to be adjusted when restoring data, for instance. Assuming 30 days/month, this amounts to $0.1667/TB/day, so a cap of $2 per day in storage cost allows for up to 12 TB. As of this writing (2018-Jun) the pricing for Backblaze B2 storage is $0.005/GB/month. (Backblaze B2 buckets only allow alphanumeric characters and hyphens.)Īnd last, if you’re going to be backing up more than the free amount of B2 storage (10 GB as of this writing), then on Backblaze’s website you will need to go to B2 Cloud Storage -> Caps and Alerts, and adjust the maximum daily storage cap. Substitute this bucket name for the placeholder MY-B2-BUCKET-NAME in this wiki.

The name for the bucket must be unique across all buckets by all Backblaze B2 users. Next, from Backblaze’s website, create a B2 bucket. You will receive a B2 Account ID and a B2 Application Key from Backblaze. The first step is to create a Backblaze account, and sign up for B2 storage.

This wiki describes how to take a large amount of data and back it up to both a local backup, such as an external hard drive or NAS, and a Backblaze B2 account using the CLI on Linux. Backblaze B2 has become a popular cost-effective online storage mechanism, and is typically less expensive than competing services such as Amazon S3.
