Abstract
One embodiment provides a storage management system. During operation, the system identifies a data file of a user. The system obtains an encrypted client registry from a primary cloud provider in a plurality of cloud providers that provide cloud storage to the user and retrieves a key associated with a device of the user by decrypting the encrypted client registry using a hash of a password associated with the user. The system obtains credentials of the plurality of cloud providers by decrypting a locally stored cloud configuration using the key and generates a plurality of coded fragments from the data file based on a generator matrix of erasure encoding. The number of coded fragments is determined based on a number of the cloud providers associated with the user. The system selects a respective coded fragment for uploading to a corresponding cloud provider in the plurality of cloud providers.
