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 A great option for managing the cleanup of outdated file versions to save on storage costs.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
