Mozy (by Dell) was a cloud backup service owned by Dell EMC that targeted customers ranging from consumers through to the enterprise. After series of acquisitions, the Mozy line was acquired from Dell and subsumed by Carbonite.Content Continues Below
Launched in 2005, Mozy has headquarters in Seattle. As of late 2017, Mozy claimed an international base of more than 6 million users and 100,000 businesses.
In 2007, EMC paid $76 million for Mozy's parent, Berkeley Data Systems, which included the Mozy online backup service. In 2008, EMC launched a subsidiary named Decho, which included Mozy.
In 2011, EMC-owned VMware bought Mozy. At the time, analysts said it was part of VMware's strategy to move customer workloads to the cloud. In 2012, EMC brought Mozy back under the EMC banner.
In 2013, EMC unveiled new enterprise features for Mozy, including mobile device backup and file sync. When EMC acquired Mozy, it was mostly for home and prosumer users, but these new features brought Mozy more into the enterprise cloud backup world. MozyEnterprise became available as a cloud backup option in EMC's Data Protection Suite.
Dell acquired EMC in 2016. As of 2017, Mozy is part of the Dell security suite.
In 2018, Carbonite acquired Mozy from Dell and began shepherding its customers from the Mozy service and support to Carbonite.
Mozy had three major products: MozyEnterprise for enterprises, MozyPro for smaller businesses and MozyHome for consumers.
MozyEnterprise protected endpoint devices and remote offices. The product was for large companies with full-time IT staff and thousands of endpoints. It backed up desktops, laptops and servers, and also features network drive support.
MozyPro enabled smaller businesses to schedule daily, weekly or monthly backups. It offered automatic backup protection and the possibility to run continuous data backups throughout the day. A business could determine the amount of bandwidth used.
Consumers would install MozyHome on a computer and then selects the files they wanted to automatically back up. Through Mozy Sync, Mozy could automatically sync files between devices -- computers, iOS and Android -- for instant access.
MozyEnterprise, MozyPro and MozyHome offered what the vendor called "enterprise-grade security." Mozy encrypted data before it was sent over the wire, during transit and at rest in Mozy's data centers. Encrypted files were sent through a secure SSL connection. In 2017, MozyEnterprise launched support for KMIP, which automatically generates per-user encryption keys that can be managed through a key management server.
Mozy cloud backup had several competitors in the market, including Carbonite. Remaining competitors include Backblaze, Acronis and Druva.
Backblaze offers personal and business cloud backup, as well as cloud storage. Backblaze stores data on its open source hardware platform Storage Pods and its cloud-based Backblaze Vault file system. Backblaze claims the dense architecture of Storage Pods allows it to offer backup at a lower price than competitors. In 2015, Backblaze introduced its B2 Cloud Storage platform, which was designed to compete with public clouds from large companies such as Amazon, Microsoft and Google, but at a lower cost.
Druva provides cloud backup and is making a move into the data management market. The enterprise-level Druva inSync product is designed for endpoints and backs up data across physical and public cloud storage. Druva Phoenix is a software agent used to back up and restore data sets in the cloud for distributed physical and virtual servers.
Acronis offers on-premise and cloud-based backup software, disaster recovery and secure data access to consumers, small-medium businesses and enterprises. The Swiss-based company claimed 5 million customers by mid-2019.
For any cloud backup product, users should note the service's limitations: It is available only over the internet, and performance depends heavily on bandwidth and connectivity.
