 Exhibit 10.28 

SECOND AMENDMENT 
 TO LOAN AND
SECURITY AGREEMENT 
 This Second Amendment to Loan and Security Agreement (this “Amendment”) is entered into as of
August 30, 2013, by and between COMERICA BANK (“Bank”) and CARBONITE, INC., a Delaware corporation (“Borrower”). 

RECITALS 
 Borrower and
Bank are parties to that certain Loan and Security Agreement dated as of May 11, 2011, as amended, modified, supplemented, extended or restated from time to time, including by that certain First Amendment to Loan and Security Agreement dated as
of August 30, 2012 (collectively, the “Agreement”). The parties desire to amend the Agreement in accordance with the terms of this Amendment. 

NOW, THEREFORE, for good and valuable consideration, the receipt of which is hereby acknowledged, the parties agree as follows: 

1. Exhibit A to the Agreement is hereby amended by amending and restating the following defined term to read as follows: 

“Revolving Maturity Date” means September 30, 2013. 

2. No course of dealing on the part of Bank or its officers, nor any failure or delay in the exercise of any right by Bank, shall operate as a
waiver thereof, and any single or partial exercise of any such right shall not preclude any later exercise of any such right. Bank’s failure at any time to require strict performance by Borrower of any provision shall not affect any right of
Bank thereafter to demand strict compliance and performance. Any suspension or waiver of a right must be in writing signed by an officer of Bank. 

3. Unless otherwise defined, all initially capitalized terms in this Amendment shall be as defined in the Agreement (as amended by this
Amendment). The Agreement, as amended hereby, shall be and remain in full force and effect in accordance with its terms and hereby is ratified and confirmed in all respects. Except as expressly set forth herein, the execution, delivery, and
performance of this Amendment shall not operate as a waiver of, or as an amendment of, any right, power, or remedy of Bank under the Agreement, as in effect prior to the date hereof. Borrower ratifies and reaffirms the continuing effectiveness of
all promissory notes, guaranties, security agreements, mortgages, deeds of trust, environmental agreements, and all other instruments, documents and agreements entered into in connection with the Agreement. Borrower hereby further affirms its
absolute and unconditional promise to pay to Bank the Advances, all other Credit Extensions and all other amounts due under the Letters of Credit and the other Loan Documents (including, without limitation, the Obligations), at the times and in the
amounts provided for therein. Borrower confirms and agrees that the obligations of Borrower to Bank under the Agreement as supplemented hereby are secured by and entitled to the benefits of the Loan Documents. The parties agree that this Amendment
shall be deemed to be one of the Loan Documents under the Agreement. Nothing in this Amendment shall constitute a satisfaction of any of Borrower’s Obligations. 

4. In order to induce Bank to enter into this Amendment, Borrower hereby represents and warrants to Bank as follows: 

4.1 The representations and warranties contained in the Agreement and the other Loan Documents were true and correct in all material respects
when made and continue to be true and correct in all material respects as of the date of this Amendment. 
 4.2 Both before and immediately
after giving effect to this Amendment and the other transactions contemplated hereby, no Event of Default, or other event or circumstance that with the giving of notice or the passage of time could become an Event of Default, has occurred and is
continuing.

 4.3 The execution, delivery, and performance by Borrower of this Amendment and the other
documents, instruments and agreements to which Borrower is a party delivered or to be delivered to Bank in connection herewith (i) are within the corporate powers of Borrower and have been duly authorized by all necessary corporate action on
the part of Borrower, (ii) do not require any governmental or third party consents, except those which have been duly obtained and are in full force and effect, (iii) do not and will not conflict with any requirement of law, Borrower’s or
any Guarantor’s articles or certificate of incorporation, bylaws, operating agreement, partnership agreement, minutes or resolutions, (iv) after giving effect to this Amendment, do not result in any breach of or constitute a default under
any agreement or instrument to which Borrower, any Guarantor or any of their respective Subsidiaries is a party or by which they or any of their respective properties are bound, and (v) do not result in or require the creation or imposition of
any mortgage, deed of trust, pledge, lien, security interest or other charge or encumbrance of any nature upon any of the assets or properties of Borrower or any Guarantor, other than those in favor of Bank. 

4.4 This Amendment and the other instruments and agreements delivered or to be delivered to Bank in connection herewith have been duly
executed and delivered by Borrower and constitutes the legal, valid, and binding obligation of Borrower, enforceable against Borrower in accordance with their respective terms, except to the extent that (i) enforcement may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws of general application affecting the rights and remedies of creditors, (ii) enforcement may be subject to general principles of equity, and (iii) the
availability of the remedies of specific performance and injunctive relief may be subject to the discretion of the court before which any proceedings for such remedies may be brought. 

4.5 Borrower does not have any right of offset, defense, counterclaim, dispute or disagreement of any kind or nature whatsoever with respect
to any of its liabilities, obligations or indebtedness arising under or in connection with any Loan Document. 
 5. As a condition to the
effectiveness of this Amendment, Bank shall have received, in form and substance satisfactory to Bank, the following: 
 (a) this
Amendment, duly executed by Borrower; 
 (b) an Affirmation and Amendment of Guaranties and Security Agreement, duly executed by each
Guarantor; 
 (c) corporate resolutions and incumbency certifications, duly executed by Borrower and each Guarantor; 

(d) an amount equal to all Bank Expenses incurred through the date of this Amendment, which amounts may be debited from any of
Borrower’s accounts with Bank; and 
 (e) such other documents, instruments and certificates and completion of such other matters, as
Bank may reasonably deem necessary or appropriate. 
 6. This Amendment may be executed in two or more counterparts, each of which shall be
deemed an original, but all of which together shall constitute one instrument.
