What's New With B2

Backblaze B2 continues to grow in popularity as developers, IT personnel and more realize the benefits of affordable cloud storage. Our B2 engineering team continues to add features and capabilities to B2 that our users identify as being helpful in getting their job done. Here’s a collection of recent updates to B2 you may find useful.

5 MB Large File part size – When working with large files, the minimum file part size can now be set as low as 5 MB versus the previous low setting of 100 MB. The range of a file part when working with large files can be from 5 MB to 5GB. We recommend using the default of 100 MB, but in cases where RAM is limited a smaller size can be useful.

SHA-1 at the end – This feature allows you to compute the SHA-1 checksum and append it to the end of the request body versus doing the computation before sending the file. This is especially useful for those applications which stream data to B2.

Cache-Control – When data is downloaded from B2 into a browser, the length of time the file remains in the browser cache can be set using the following syntax:

{“cache-control” : “max-age-NNN”}
where NNN is the number of seconds to cache the file.

Cache-Control policies are set at the bucket level using the b2_create_bucket and b2_update_bucket API calls. Setting this policy is optional.

Life Cycle Rules – Create rules that allow you to manage the length of time deleted files will remain in your B2 bucket before deletion. A great option for managing the cleanup of outdated file versions to save on storage costs.

Time Machine backup – You may know that you can use your Synology NAS as the destination for your Time Machine backup. With B2 you can also sync your Synology NAS to B2 for a true 3-2-1 backup solution.

B2 user Groups – Backblaze B2 users can now use Backblaze B2 along with the new Backblaze Groups Management functionality. Group Management allows administrators to pay for their team’s B2 usage and Managed Groups even allow administrators to share access to B2-enabled Backblaze accounts.

B2 Integrations

Here are a couple of recently completed B2 integrations:

Retrospect – A proven backup and archive service for servers, virtual machines and more. Now you can choose Backblaze B2 as a cloud storage destination.

Cantemo – A media asset management system that allows you to create sophisticated rules to automatically route, archive and restore an asset or collection to and from B2 Cloud Storage.

Odds-and-Ends

If you’re new to B2, check out our recent B2 Demo webinar (registration required). The demo will introduce you to B2 and show you how you can use B2 to backup, archive, and sync your data to the B2 cloud.

If you have suggestion for a B2 feature or enhancement, let us know by contacting Backblaze B2 support. Thanks.

    i need a solution that can be used as an external file server through ftp.

    Why is the user friendliness of this site so bad? I can’t figure out even WHAT exactly I can do here, how to see pricing to buy anything, how to do anything at all. I am lost.

    How do I rename a file or folder?

  • Kristian

    What missing now is some sort of “append only” access for backup scripts. For backup purpose B2 isn’t worth much, if the hacker can just delete all the backups.

  • Justin Winokur

    I was just wondering, is there a plan for Backblaze to release an official API wrapper in some languages such as Python? Your documentation is great but still sets a high learning curve.

    Also, is there a plan to support renaming files once they are in Backblaze? Or, reseting some extra meta-data which can be used as an alternative name?

    Thanks!

  • I still see authorize_account returning “minimumPartSize”: 100000000. Will this be updated to 5 MB?

    • Sorry, I now see that absoluteMinimumPartSize and recommendedPartSize replace this field.

  • Joe Elliott

    Can you update header options on files already uploaded? Like cache-control, or or other?
