Explanation of Responses:

1. The filing of this Form 3 shall not be construed as an admission that Whetstone Capital Advisors, LLC ("WCA") or David Atterbury, the manager of WCA, is or was for the purposes of Section 16(a) of the Securities Exchange Act of 1934, as amended, or otherwise the beneficial owner of any of the Common shares, par value of $0.001 per share (the "Common Stock"), of BackBlaze, Inc. (the "Issuer") purchased by certain private investment funds advised by WCA (collectively, the "Whetstone Accounts"). Pursuant to Rule 16a-1, both WCA and Mr. Atterbury disclaim such beneficial ownership.

2. WCA holds indirectly the shares of Common Stock of the Issuer through the Whetstone Accounts, for which WCA is the Investment Manager. David Atterbury reports the Common Stock held indirectly by WCA because, as the manager of WCA at the time of purchase, he controlled the disposition and voting of the securities.

	David A. Atterbury, Manager of Whetstone Capital Advisors, LLC	11/22/2021
