Backblaze, the cloud-based backup service, introduced a 2.0 release this week. CEO Gleb Budman describes 2.0 as “unlimiting unlimited” in a blog post.

With Backblaze, you can back up your entire Mac’s contents to a secure online repository, for safe offsite storage and recovery in the event of a catastrophic failure.

The service hasn’t put limits on the maximum archive size or the bandwidth customers could use to back up content, but 2.0 improves performance and is “more unlimited” than before. Specific enhancements include:

• Unlimited single file size, removing a previous 9GB maximum.
• Unlimited file types, with support for backing up VMware, Parallels and other virtual machines, ISO images and every other file type as well.
• Maximum performance – an “automatic throttle” has been added that helps users configure Backblaze to use its Internet connection more efficiently. File batching speeds the transfer of small files, hardware acceleration has been added, RAM use has been optimized, and more.

New customers get 2.0 right away; existing users will be transitioned to the new service “over the next few weeks,” according to Budman.

Pricing starts at $5 per month, with discounts available if you go on annual or biennial plans.
