A system comprising:

• memory;
• and
• one or more processing devices configured to:
• receive information about an electronic file stored on a primary cloud drive of a user,
• receive one or more user-defined attributes associated with the electronic file, the one or more user-defined attributes indicative of a home network associated with the electronic file,
• generate, based on the one or more user-defined attributes, a security token that is configured to control access to the electronic file based on whether the access is from within or outside of the home network, and
• store a copy of the electronic file on a secondary cloud drive separate from the primary cloud drive, wherein the copy of the electronic file is stored on the secondary cloud drive in association with the security token.

One or more machine-readable storage devices storing instructions that are executable by one or more processing devices to perform operations comprising:

• obtaining information about an electronic file stored on a primary cloud drive of a user;
• obtaining one or more user-defined attributes associated with the electronic file, the one or more user-defined attributes indicative of a home network associated with the electronic file;
• generating, based on the one or more user-defined attributes, a security token that is configured to control access to the electronic file based on whether the access is from within or outside of the home network;
• and
• storing a copy of the electronic file on a secondary cloud drive separate from the primary cloud drive, wherein the copy of the electronic file is stored on the secondary cloud drive in association with the security token.
