Mozy is an online backup service for both Windows and Mac users. Linux is currently not supported. The cloud service allows users to back up data continuously, manually, or schedule updates. Mozy offers backup storage space for home and business users. Originally released as a consumer product for end-users (MozyHome), Mozy later released a remote backup utility for businesses called MozyPro, with additional functionality and an administrative portal. In 2007 Mozy was acquired by EMC, and in 2013 Mozy was included in the EMC Backup Recovery Systems division's solution portfolio.
Founded in 2005, Mozy was originally created by Berkeley Data Systems of American Fork, Utah.
In October 2007, EMC acquired Berkeley Data Systems, along with the Mozy product line for $76 million. In November 2008, EMC Corporation created Decho Corporation, formed from the assets of Berkeley Data Systems and PI corporation. Mozy is headquartered in Seattle, Washington, though the majority of its employees are in its Pleasant Grove, Utah offices.
Mozy produces three products: MozyHome, MozyPro, and MozyEnterprise.
MozyHome is the consumer version of the Mozy backup service. It is available to buy on a monthly subscription, or on various other plans. In January 2012 Mozy opened the public beta of its cloud storage / synchronization feature called Mozy Stash, for free. MozyHome previously offered users an unlimited amount of storage space. In February 2011 they closed the unlimited service and are charging according to how much space is used. 
MozyPro is the business class version of the Mozy backup service. Originally launched in 2007  MozyPro pricing was updated in 2012 for businesses to back up any number of computers for one price. For server backup, a business purchases the Server Pass for an additional monthly charge and back up as many servers as they like.
MozyEnterprise is for larger organizations and includes support for Active Directory, user groups (in a company), and more administrator control over user rights. For Mozy administrators, the company detailed its keyless activation and pooled storage features in a 2013 EMC blog post. Mozy has more than 800 enterprise customers. With all Mozy products, after the initial backup, Mozy only backs up new or changed portions of files. Backups can take place when the computer is not in use, either automatically, and at scheduled times. All user data is encrypted locally with strong encryption prior to transfer via a 128-bit SSL connection. Users can choose a managed encryption key or choose a personal key for added security. Mozy's security does not let end-users shortcut the data deletion process. Data is stored in world-class data centers and Mozy is both SSAE 16 Type 2 and ISO 27001 certified. In June 2011, SSAE 16 replaced SAS 70. Any organization that provides a service for a publically traded company that has an impact on its financial statement will need an SSAE 16 report.
In May 2010, Mozy launched MozyHome 2.0 and MozyPro 2.0, adding support for local backup, increased performance and a new user interface for consumers and small businesses.
In 2011, Mozy launched "restore manager" - a software tool to simplify the process of retrieving files from the Mozy cloud. It is also possible to restore through the Mozy client, in the Windows file tree or by ordering DVD disks from Mozy. Users can restore either the last version of any file backed up or any previous iteration backed up in the preceding thirty days or ninety days depending on the product.
